A lot of work has 253 been done, but a good amount remains to achieve 2.8.0 goals. 254 Please read the UPGRADING notes. 255 256 - Added support for SSL via the Mozilla NSS library, in addition to the 257 existing OpenSSL support. 258 259 - Added a new driver, nutdrv_qx, for Megatec/Qx devices. This driver will 260 eventually replace the blazer_ser and blazer_usb drivers. In particular, it 261 adds support for Voltronic Power devices. 262 263 - Increased USB_TIMEOUT to standards-compliant 5.000 seconds in most drivers. 264 This should reduce the number of timeouts on low-speed USB 1.1 devices. 265 266 - The jNut Java source has been split into a separate GitHub repository. 267 268 - Added many devices to the HCL. Of particular note are many Tripp Lite USB 269 HID PDC models which were tested against NUT by Tripp Lite. 270 271 - Reworked some visual elements of the HCL. The output is better tailored for 272 graphical and text-only browsers, but suggestions are welcome for additional 273 accessibility enhancements. 274 275 - Also increased timeouts and added redundant commands to improve reliability 276 of mge-utalk driver. 277 278 - Added the apcupsd-ups driver to interoperate with apcupsd installations. 279 280 - Added documentation on creating subdrivers for snmp-ups and nutdrv_qx. 281 282 - Added new drivers for the Riello UPS product line (riello_ser/riello_usb). 283 284 - Many improvements to the BCM/XCP drivers have been merged in. This includes 285 an improved data reception loop, and additional mappings. 286 287 - Added a few variables to the Powercom HID mappings. 288 289 - Updated the apcsmart driver, and renamed the previous driver to apcsmart-old. 290 291 - Fixed the battery percentage calculation in the bestfcom driver. 292 293 - libnutclient has been added as a C++ alternative to libupsclient. 294 295 - Packaging files for Solaris and HP-UX (sponsored by Eaton) 296 297 - Fix shutdown of Eaton HID, using usbhid-ups and mge-shut 298 299 - usbhid-ups: final fix for APC Back UPS ES. APC Back UPS ES devices have 300 buggy firmware, and this version does not cause a regression. The max_report 301 variable should be set automatically based on the USB identification values. 302 303 - nut-scanner: fix crash 304 305 - IPMI support can handle more different versions of FreeIPMI 306 307 - Support power supplies scan over the network 308 nut-scanner can now scan for power supplies with IPMI over LAN. 309 This is currently limited to IPMI 1.5 only 310 311 - Implement a framework to spell check documentation source files, 312 using Aspell. This includes an interactive build target (make 313 spellcheck-interactive), and an automated one (make spellcheck), 314 mainly for QA / Buildbot purpose. Note that a base NUT dictionary 315 is also available (docs/nut.dict), providing a glossary of terms 316 related to power devices and management 317 318 - Improve systemd integration 319 320 - snmp-ups: Fixed a crash on outlet management, and added delta_ups MIB 321 support. Also fixed mappings for upsBypassVoltage, upsBypassCurrent, and 322 upsBypassPower in three-phase IETF MIB. 323 324--------------------------------------------------------------------------- 325Release notes for NUT 2.6.5 - what's new since 2.6.4: 326 327 - This release fixes an important regression in upssched: 328 any upssched.conf command that takes a second argument resulted in 329 a defective frame sent to the parent process. Thus, the command was 330 not executed (report and patch from Oliver Schonefeld) 331 332 - Website hosting: free NUT from Eaton website hosting 333 NUT website (http://www.networkupstools.org) is no longer hosted by Eaton. 334 Arnaud Quette (NUT project leader) has taken over NUT hosting on his own, 335 to give NUT back some independence. 336 This effort is also part of a logic to stop crediting Eaton for 337 contributions from others (especially Arnaud Quette, as an individual). 338 The new hosting service is located, as for Arnaud's blog 339 (http://arnaud.quette.fr) on Gandi servers, using PaaS. This will allow 340 more flexibility and automation of the release process 341 342 - macosx-ups: new OS X Power Sources meta-driver 343 Mac OS X provides UPS status information in a format similar to 344 what is shown for laptop batteries. This driver will convert that 345 information into a format compatible with NUT (Charles Lepple). 346 347 - support for new devices: 348 Eaton ePDU Switched 349 Online Zinto A (USB ID 0x06da:0x0601) 350 REDi Blazer 400VA / 600VA / 800VA 351 UNITEK Alpha650ipF and Alpha650ipE (USB ID 0x0f03:0x0001) 352 353 - mge-shut driver has been replaced by a new implementation (newmge-shut). 354 In case of issue with this new version, users can revert to oldmge-shut. 355 356 - First NUT virtualization package: NUT now supports integration with 357 VMware ESXI 5.0, through a native VIB package. This is, for the time 358 being, an external effort from René Garcia (refer to the Download section 359 on NUT website). But work is underway to improve this integration, and 360 include it in the NUT source tree 361 362 - IPMI support (nut-ipmipsu driver and nut-scanner): prepare for supporting 363 API changes in upcoming FreeIPMI versions 1.1.x and 1.2.x. 364 365 - snmp-ups now supports high precision values for APC, and more variables 366 367 - the NUT variables and commands namespace has been fixed and 368 completed, with the known and used variables that were missing. 369 370 - more bugfixes, cleanup and improvements, on both source code and 371 documentation. 372 373--------------------------------------------------------------------------- 374Release notes for NUT 2.6.4 - what's new since 2.6.3: 375 376 - This release Fix an important vulnerability in upsd 377 (CVE-2012-2944: upsd can be remotely crashed) 378 379 NUT server (upsd), from versions 2.4.0 to 2.6.3, are exposed to 380 crashes when receiving random data from the network. 381 This issue is related to the way NUT parses characters, 382 especially from the network. Non printable characters were missed 383 from strings operation (such as strlen), but still copied to the 384 buffer, causing an overflow. 385 Thus, fix NUT parser, to only allow the subset of ASCII charset from 386 Space to ~ 387 (Reported by Sebastian Pohle, Alioth bug #313636, CVE-2012-2944) 388 389 A separate patch, which applies to any faulty version, is also available: 390 http://trac.networkupstools.org/projects/nut/changeset/3633 391 392 For more information, refer to the Common Vulnerabilities and Exposures: 393 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2944 394 395 - A static source code analysis has been done by Michal Hlavinka from RedHat, 396 using Coverity (12 issues fixed). 397 398 - Add new "LIST CLIENTS" and "NETVER" commands to NUT network protocol. 399 "NETVER" allows to retrieve the Network protocol version, while 400 "LIST CLIENTS" provides the list of clients connected to a device. 401 Refer to the developer guide, "Network protocol information" section for 402 more information. 403 404 - Support of ranges of values for writable variables has been added, to 405 complete the existing enumerated values mechanism. This will start to 406 appear in some drivers soon, beginning with Eaton. Refer to the developer 407 guide, "Creating a new driver..." section for more information. 408 409 - PyNUT.py has been updated to version 1.2.2, adding support for 410 LIST CLIENTS, FSD, HELP and VER (Rene Martín Rodríguez) 411 412 - support for new devices: 413 AEG Power Solutions PROTECT HOME 414 more APC SNMP cards 415 ATEK Defensor range 416 all Borri models 417 all COVER ENERGY SA 418 CyberPower OR700LCDRM1U, PR6000LCDRTXL5U and CP1000PFCLCD 419 Dell UPS Network Management Card 420 Dynamix 1000VA USB 421 Eaton Management Card Contact (ref 66104) 422 EVER POWERLINE RT / 11 / 31 and DUO II Pro 423 GE Digital Energy GT Series 1000-3000 VA 424 Gtec models 425 all recent HP serial / USB UPS (G2, G3 and R/T models, ) and HP UPS 426 Management Module 427 Ippon INNOVA RT 428 KOLFF BLACK NOVA 429 Lexis X-power Tigra 1kVA 430 Microline C-Lion Innova 431 Online Yunto YQ450 432 PowerShield Defender 1200VA 433 PowerWalker Online VFI LCD, Line-Interactive VI LCD and Line-Interactive VI 434 Riello Netman Plus 102 SNMP Card 435 Tripp-Lite OMNISMART500 436 437 - apcsmart has received some fixes to work better on Mac OS X, and in general 438 439 - bcmxcp has improved support for battery status, and better supports 440 PW9120 units 441 442 - bestfortress has improved Best Fortress LI675VA support 443 444 - blazer_ser and blazer_usb now try to automatically estimate high and low 445 voltages, to be able to calculate battery charge ; support for online 446 Innova UPS (T, RT and 3/1 T) has been added ; Best UPS support has been 447 improved, to prepare for superseding bestups driver 448 449 - bestups has also received some care, though users are encouraged to switch 450 to blazer_ser, since bestups will soon be deprecated. 451 452 - newmge-shut has been heavily improved. However, replacement of the 453 current mge-shut has been postponed to the next release, due to the CVE 454 issue. 455 456 - oneac 0.80 improves support for all families of Oneac (EG, ON, OZ and OB), 457 including more data and instant commands (Bill Elliot). 458 459 - usbhid-ups: for Eaton devices, ups.start.auto is now automatically adjusted 460 for shutdown.{return,stayoff} to behave as expected ; Liebert firmwares with 461 incorrect exponents have also been addressed. 462 463 - snmp-ups now provides support for UPS shutdown, based on usbhid-ups 464 mechanisms (composite commands and fallback). Composite commands are also 465 supported now. This means, for example, that if 'shutdown.return' is not 466 supported, a combination of 'load.off' + 'load.on' may be used ; 467 Actual validity of instant commands is now tested before commands addition ; 468 Eaton/MGE MIB has been cleaned and completed ; 3-phases support has been 469 added to Socomec Netvision MIB ; HP/Compaq MIB has been completed, with 470 thresholds, nominal values and more commands. 471 472 - nut-scanner now also has libupsclient has a weak runtime dependency ; more 473 docs and bugfixes have also happened. 474 475 - Provide an Uncomplicated Firewall (UFW) profile (nut.ufw.profile) 476 477 - Riello protocols have been officially published in NUT protocols library: 478 http://www.networkupstools.org/ups-protocols.html#_riello 479 480 - Duplicate instances of upsd / upsmon are now detected upon startup 481 482 - NUT variables namespace has been completed with missing variables and 483 commands that are already known and standard 484 485 - upslog now comes with a companion file, for logrotate configuration 486 487 - more devices embed NUT for power protection, now including Thecus NAS range 488 489 - more bugfixes, cleanup and improvements, on both source code and 490 documentation, with a good bunch from Greg A. Woods. 491 492--------------------------------------------------------------------------- 493Release notes for NUT 2.6.3 - what's new since 2.6.2: 494 495 - nut-scanner is now more portable, and provides more coherent option names. 496 IPMI support has also been added, to discover local power supplies. 497 This version brings weak runtime dependencies in libnutscan, which allows to 498 compile nut-scanner with all options and to run according to the available 499 dependencies (USB, SNMP, IPMI, ...). 500 501 - libnutscan now provides pkg-config support and the needed header files are 502 distributed. Some documentation is also available in the developer guide and 503 manual pages have been updated and completed. 504 505 - support for new devices: Cyber Power Systems with SNMP RMCARD (100, 201, 506 202 and 301) ; Dynamix 650VA USB ; LDLC UPS-1200D ; Tecnoware UPS ERA LCD 507 0.65 ; Powercom BNT-xxxAP (USB ID 0d9f:0004) ; Various USB devices using 508 UPSilon 2000 software. 509 510 - apcsmart has received minor correction. 511 512 - bcmxcp_usb now handles disconnection issues and reconnection mechanism. 513 514 - blazer_usb enables again inclusion of buggy USB Device and Vendor IDs in 515 udev rules file ; language ID support has been added for USB units from 516 LDLC, Dynamix and other no names. 517 518 - nut-ipmipsu has also received some improvements. 519 520 - snmp-ups has fixed outlets reported current in aphel_genesisII MIB ; 521 MGE 3 phases handles better low battery condition ; support for Cyber Power 522 Systems with SNMP RMCARD has been added ; support of the newer Eaton ePDUs 523 has been improved. 524 525 - upsd doesn't anymore fail to start if at least one of the listening 526 interface is available. This is needed on systems where either IPv4 or IPv6 527 is disabled, and no explicit LISTEN directive has been specified. 528 529 - Avahi support is now automatically enabled, upon detection 530 531 - jNut (NUT Java interface) adds device discovery support, through a 532 nut-scanner wrapper ; jNutWebAPI, a HTTP/JSON web service interface, has 533 also been added to interact with upsd and nut-scanner. 534 535 - Base files for HPUX packaging have been added. This is still a work in 536 progress. 537 538 - Compilation on IBM AIX has been fixed (namespace conflict with ctypes). 539 540 - more bugfixes, cleanup and improvements, on both source code and 541 documentation. 542 543--------------------------------------------------------------------------- 544Release notes for NUT 2.6.2 - what's new since 2.6.1: 545 546 - NUT can now monitor power supply units (PSU) in servers, through IPMI, using 547 the new experimental 'nut-ipmipsu' driver. Users are encouraged to test it, 548 and send feedback and debug output to the development mailing list. 549 This requires GNU FreeIPMI (0.8.5 or higher) development package or files. 550 Thanks goes to Al Chu, FreeIPMI project leader, for his help during this 551 development. 552 553 - NUT now provides a tool, called 'nut-scanner', to discover supported devices, 554 both local and remote. nut-scanner will help to ease the configuration step, 555 and power infrastructure discovery. 556 This development, sponsored by Eaton, supports the following methods: 557 * USB, 558 * SNMP, 559 * XML/HTTP (from Eaton), 560 * NUT servers, using the classic connect or Avahi / mDNS methods. 561 562 IPMI support will be added in the next release. 563 A separate library, called 'libnutscan', is also available to provide these 564 feature. Future NUT releases will provides binding for the supported 565 languages (Perl, Python and Java). 566 567 - NUT now provides a Java interface called 'jNut'. 568 This development, sponsored by Eaton, is currently limited to the client 569 interface.

Magalhaes] 1109 1110 - The apcsmart driver has fixed APC600 support. 1111 1112 - The etapro driver fixes brokenness due to ser_get_line use 1113 [Marek Michalkiewicz] 1114 1115 - The new upscode2 driver supports Fiskars, Compaq and Powerware 1116 devices. 1117 [Niels Baggesen, Havard Lygre] 1118 1119 - The tripplite driver has fixed a battery charge bug 1120 [Cedric Tefft] 1121 1122--------------------------------------------------------------------------- 1123Release notes for NUT 2.0.1 - what's new since 2.0.0: 1124 1125 - The bestuferrups driver has been forked into the new bestfcom driver 1126 which has better handling of the inverter status alarm messages and 1127 more. 1128 [Kent Hill] 1129 1130 - Mustek UPS support returns with two drivers which have overlapping 1131 coverage: mustek and powermust. 1132 [powermust: Carlos Rodrigues, mustek: Martin Hajduch] 1133 1134 - Additional CyberPower Systems hardware is supported with the new 1135 cpsups driver. Three recognized models are the CPS1500AVR, 1136 CPS1100VA, and OP500TE. 1137 [Walt Holman, Brad Sawatzky] 1138 1139 - The genericups driver can now generate staleness warnings in 1140 specific cases where the UPS provides a way to test for its 1141 presence. See the "CON" setting in ups.conf for more details. 1142 [stan / saticed.me.uk] 1143 1144 - Documentation for monitoring a Back-UPS RS 500 on a system without 1145 USB ports has been added to the cables directory. 1146 [Martin Edlman] 1147 1148 - The everups driver now supports types 73-76 (NET 700/1000/1400/500-DPC) 1149 [hunter] 1150 1151 - The new metasys driver supports Meta System models: Line, 1152 HF Millennium, HF Top Line, ECO Network, ECO, Ally HF, Megaline 1153 [BlaXwan] 1154 1155 - The ippon driver now allows user-defined settings for the delay 1156 before switching off, and the delay before powering on. 1157 [Yuri Elizarov] 1158 1159 - The victronups driver is now at version 0.1.9, which adds many 1160 instant commands: calibration control, battery and front panel tests, 1161 and bypass control. 1162 [Gert Lynge] 1163 1164 - The tripplite driver has received a major overhaul to bring it up to 1165 working condition for the 2.0 tree, including code cleanups, several 1166 new variables, commands, and user-definable parameters. See 1167 ChangeLog for more. 1168 [Nicholas J Kain] 1169 1170 - The mge-utalk driver has been upgraded to version 0.81, which fixes 1171 the lack of read-write variables and loss of sync on models which 1172 don't support restoring settings. 1173 [Arnaud Quette] 1174 1175 - The Micro Ferrups model RE is now supported by the bestuferrups 1176 driver. The driver will also now read the ambient temperature and 1177 will no longer constantly report the data as stale. 1178 [Tim Thompson] 1179 1180 - The fentonups driver's init sequence has been reworked to work better 1181 with some hardware, including a fix to the parser code. 1182 [MLH] 1183 1184 - A workaround has been added to the hidups driver to avoid variables 1185 which are stuck by calling HIDIOCINITREPORT in every poll. 1186 [Stuart D. Gathman] 1187 1188 - SOLA 610 UPS hardware and others which do not support the ID command 1189 may now be monitored by the bestups driver after forcing ID= in 1190 ups.conf. 1191 [Jason White] 1192 1193 - "pollinterval" is now available via driver.parameter for consistency. 1194 [Arnaud Quette] 1195 1196 - The mge-shut and newhidups drivers, along with the supporting 1197 hidparser/libhid code have received many updates, including lowering 1198 USB bandwidth consumption, driver unbinding (only in Linux), code 1199 cleanups, and more which can be seen in the ChangeLog file. 1200 [Arnaud Quette] 1201 1202 - The fentonups driver now recognizes several more Megatec protocol 1203 units: 1204 1205 SuperPower HP360, Hope-550 [Denis Zaika] 1206 Unitek Alpha 1000is [Antoine Cuvellard] 1207 1208 - Some variables like uc_sigmask were renamed to avoid clashes with 1209 symbols on systems like HP/UX. 1210 1211 - All man pages have been reworked to switch literal "-" characters to 1212 hyphens or "\-" as appropriate. 1213 [Shaul Karl] 1214 1215 - upssched's CANCEL events were broken following the change to 1216 text-based socket messages in 1.5 and have been fixed. 1217 [Steven Schoch] 1218 1219 - Calls to varargs functions with raw strings from the config files 1220 without an intervening "%s" have been fixed in upsmon, upssched, 1221 snmp-ups and upsd. 1222 [Ulf Harnhammar] 1223 1224--------------------------------------------------------------------------- 1225Release notes for NUT 2.0.0 - what's new since 1.4.x: 1226 1227 - The new naming scheme for variables and commands (introduced in 1.4) 1228 is now mandatory. The 1.4 tree supported both the old (STATUS) and 1229 the new (ups.status) as a transitional release, and now that time is 1230 over. 1231 1232 This means that 2.0 is generally smaller than 1.4 code, since the 1233 interim compatibility hacks have been removed. 1234 1235 - New serial handling code has been added, with greatly simplified 1236 operations. The old mess involving repeated calls to sigaction, 1237 alarm, and read has been condensed to a select-read loop. 1238 1239 This change allows drivers which don't do any serial communications 1240 at all (hidups, snmp-ups) to drop that baggage, so they are a bit 1241 smaller when compiled. 1242 1243 - The drivers now recognize "chroot=' and 'user=' in the global section 1244 of ups.conf. This means you don't have to use -r and -u when 1245 starting upsdrvctl. 1246 1247 - upsmon now supports the -K argument to check for the presence of the 1248 POWERDOWNFLAG file. If it exists and contains the magic string, then 1249 upsmon will exit(EXIT_SUCCESS). Otherwise, it will 1250 exit(EXIT_FAILURE). 1251 1252 This feature can be used to simplify shutdown scripts, since now you 1253 don't have to keep the script in sync with the upsmon.conf. 1254 1255 - Many small things like signed value comparisons, int vs. size_t and 1256 proper use of const/struct were fixed throughout the source. These 1257 were mostly for correctness, but a few potential bugs involving very 1258 big or very small numbers were fixed at the same time. 1259 1260 - The access control system in upsd.conf has been reworked and 1261 simplified. Since access levels have become meaningless in recent 1262 releases, the new system is just ACCEPT <acl> or REJECT <acl>. 1263 1264 If you are upgrading from a previous version of the software, you 1265 will have to edit your upsd.conf to use this method. See 1266 the UPGRADING file for more details. 1267 1268 - The build process now halts when make fails in one of the 1269 subdirectories. 1270 [Petter Reinholdtsen, Charles Lepple] 1271 1272 - Helper data for using upsclient via pkgconfig is now created if 1273 pkgconfig is detected when configure runs. 1274 [Arnaud Quette] 1275 1276 - The polling interval in drivers may now be set with 'pollinterval' 1277 in ups.conf. 1278 [Gabriel Faber] 1279 1280 - Blazer UPS equipment is now supported with the blazer driver. 1281 [Phil Hutton] 1282 1283 - Energizer USB UPS hardware is now supported on Linux with a new 1284 experimental driver. 1285 [Viktor T. Toth] 1286 1287 - The newhidups driver has been merged as the first step towards 1288 portable USB UPS support. This will eventually replace the old 1289 Linux-only hidups driver. The newhidups driver is tagged 1290 experimental since it is under active development. 1291 [Arnaud Quette, Charles Lepple] 1292 1293 - The newapc driver has been renamed to apcsmart, replacing the old 1294 driver with that name. If you used the newapc driver, be sure to 1295 delete the old binary and fix your ups.conf. 1296 1297 - The apcsmart driver now supports asynchronous notification data 1298 from the hardware, which means it can wake up as soon as something 1299 happens. This affects the OL/OB/LB/RB data in ups.status, and 1300 generally reduces the latency in dispatching status changes by a few 1301 seconds. 1302 1303 - The apcsmart driver can now support quirky hardware which does not 1304 provide the usual listing of valid command characters. This feature 1305 is necessary to monitor new models like the APC CS 350 and old ones 1306 like the Matrix 5000. It also now has sdtype=4 to handle the strange 1307 shutdown behavior on the CS series. 1308 1309 - The belkin driver now works around broken firmware version 001, 1310 avoiding a lengthy delay at startup. It also implements the shutdown 1311 sequence differently, and should actually work on more hardware now. 1312 1313 - The bestups driver has been slowed down to play nicer with the 1314 hardware, and is much more reliable as a result. Among other things, 1315 it should always detect the UPS on the first try, meaning no more 1316 "dot dot dot" when it starts. 1317 1318 - The cyberpower driver is no longer tagged experimental, and now 1319 supports powering off the load. It also supports battery tests via 1320 instcmds. 1321 1322 - Effekta MT 2000 RM hardware is now supported by the fentonups driver. 1323 [Christoph Moar] 1324 1325 - The new safenet driver supports UPS hardware that uses the protocol 1326 of the same name. This includes models from many manufacturers, 1327 including Fairstone, Fenton, Gemini, Powerwell, Repotec, Soltec and 1328 Sweex. See the README or driver.list for the full details. 1329 [Arjen de Korte] 1330 1331 - The genericups driver now has type 20 to monitor the Powerware 5119 1332 RM. See http://lists.exploits.org/ups/Oct2003/00052.html. 1333 [Daniel Thompson] 1334 1335 - The belkinunv driver has been added to allow monitoring Belkin 1336 Universal UPS hardware. 1337 [Peter Selinger] 1338 1339 - Cyber Power Systems 1100AVR hardware which has a different protocol 1340 than the existing binary type (supported by 'cyberpower') is now 1341 supported by the experimental cyberpower1100 driver. 1342 [Walt Holman] 1343 1344 - upsdrvctl now returns success or failure information in the exit 1345 code. Any failure during a requested operation will result in a 1346 nonzero value (specifically EXIT_FAILURE). 1347 1348--------------------------------------------------------------------------- 1349Release notes for NUT 1.4.0 - what's new since 1.2.x: 1350 1351 - The drivers and upsd now communicate over Unix domain sockets instead 1352 of state files, shared memory, or state files with mmap. This change 1353 makes many things possible, including the new dynamic variable and 1354 command naming scheme described below. 1355 1356 There is a new development tool called sockdebug in the server 1357 directory for debugging driver-server communications on the sockets. 1358 1359 - The old static variable scheme has been replaced by a new dynamic 1360 implementation. Vague names have been turned into meaningful names 1361 that fit into an organized system. UTILITY is now input.voltage. 1362 OUTVOLT is now output.voltage. 1363 1364 This also applies to the names of instant commands. BTEST1 is 1365 test.battery.start, and BTEST0 is test.battery.stop. 1366 1367 The old names are still supported for compatibility with older 1368 clients. This compatibility mode will be maintained throughout 1369 the 1.4 series, and will be gone by the release of 2.0. Users 1370 with older clients are encouraged to upgrade their software 1371 during this time. 1372 1373 - The network protocol has been expanded to handle these new names. 1374 Older functions which only apply to the old names will continue to 1375 be supported through the 1.4 series. 1376 1377 - The drivers and server (upsd) can now change their user ids and 1378 chroot themselves with the new -u and -r arguments. This lets you 1379 create a "chroot jail" with the bare minimum components. 1380 1381 This technique is used to provide a higher degree of security. If 1382 someone exploited upsd to get a shell somehow, they would be stuck 1383 in the jail. 1384 1385 - upssched now explicitly confirms reception of timer commands before 1386 exiting. This was done to avoid a race where one process would 1387 exit right when another one was starting. The second one would 1388 believe its command had been handled when it had been lost. 1389 1390 - upslog has been reworked to use standard getopt parsing to provide 1391 the monitoring settings. The old way of specifying arguments is 1392 still supported for backwards compatibility. 1393 1394 upslog has also been changed to only parse the format string once, 1395 rather than doing it every time through the loop. This should 1396 provide a minuscule drop in CPU utilization. 1397 1398 - Usernames are now required in upsmon and upsd. This means that you 1399 must add a username to your MONITOR lines in upsmon.conf and then 1400 create a matching user in upsd.users. 1401 1402 Installations from the 1.2 era probably already use usernames, so 1403 this mostly affects those from 1.0 and before. 1404 1405 - Drivers are now pinged regularly by upsd when they aren't posting 1406 updates about the UPS status. This provides another check in the 1407 data validation process. If upsd fails to get a response within 1408 a few seconds, the UPS will be marked stale. 1409 1410 - A few minor memory leaks were discovered with valgrind and squashed. 1411 1412 - upsstats now reuses connections to upsd when cycling through multiple 1413 entries in the hosts.conf. This makes things a bit faster and 1414 avoids some of the noise in the syslog. 1415 1416 This only applies to entries that are adjacent. To take advantage 1417 of this feature, you may have to rearrange them. 1418 1419 MONITOR ups-1@host-1 ... 1420 MONITOR ups-1@host-2 ... 1421 MONITOR ups-2@host-2 ... 1422 MONITOR ups-3@host-3 ... 1423 1424 Connection reuse for nonadjacent entries may be considered in the 1425 future. 1426 1427 - upsd now warns about insecure configuration files at startup. 1428 These files (upsd.conf, upsd.users, and the certfile) should 1429 only be readable by upsd. Never make them world-readable. 1430 1431 - The programs no longer print "shutting down" when they are just 1432 exiting. This was changed to avoid confusion about the term, since 1433 "shutting down" has a special meaning in UPS software. 1434 1435 - Signal handlers no longer do any significant amount of work. Some of 1436 the programs used to do numerous things in there, raising concerns 1437 about reentrancy. They now set flags and allow the main loop to do 1438 the actual work from there. 1439 1440 - A bug in upsmon where NOTIFYFLAG settings could be ignored was fixed. 1441 1442 - Group handling has been changed. configure no longer accepts 1443 --with-group, and the programs no longer setgid() to a hardcoded 1444 value. They now setgid() to the primary group of whatever the 1445 user value may be. 1446 1447 This may be compiled in with --with-user as before, and many programs 1448 accept -u to override it at runtime. 1449 1450 - The state path is no longer created during 'make install'. Users 1451 are now expected to create it themselves. This removes a lot of 1452 evil complexity from the build and install sequences. 1453 1454 - upsd no longer implements the DROP access command, as it 1455 could confuse the clients by getting them out of sync. DROP is now 1456 implemented as DENY, which sends an error message. If you use DROP, 1457 you should change it to DENY rather than relying on this 1458 compatibility measure. 1459 1460 - The belkin driver no longer reports OFF and OL at the same time. 1461 1462 - The bestups driver no longer sleeps during polls, which makes it 1463 more responsive to things like instant commands. 1464 1465 - The cyberpower driver now has much better hardware detection code 1466 and no longer freezes at startup under some conditions. It also now 1467 supports the shutdown function. Instant commands for shutdowns and 1468 battery tests were also added. 1469 1470 - The dummyups testing driver has been removed. The dummycons testing 1471 driver can do everything that dummyups once did and much more. 1472 dummycons is also now built by default for easier testing. 1473 1474 - The newapc driver has been reworked to take advantage of the new 1475 internal driver state functions. Some variables without an obvious 1476 purpose were dropped. 1477 1478 - The newapc driver now sends all five bytes when using sdtype 1. 1479 Previously it didn't send the entire string, and it didn't work. 1480 [Don Lewis] 1481 1482 - The hidups driver has been expanded to allow for setting variables, 1483 a shutdown sequence, and more. 1484 [Arnaud Quette] 1485 1486 - The mge-utalk driver had trouble establishing communications in 1487 some cases due to the RTS line being set. This has been fixed. 1488 1489 The mge-shut driver has been added to the tree, and has replaced 1490 the older mge-ellipse driver. 1491 [Arnaud Quette, Philippe Marzouk] 1492 1493 - Outlet-level control has been defined in the variable tree, and will 1494 be added to drivers where the hardware supports it. This can be 1495 used to shut down some components earlier than others to prolong 1496 your runtime on battery. 1497 1498 This is supported in the mge-shut driver now, and may show up in 1499 others before long. 1500 [Arnaud Quette] 1501 1502 - KIN-2200AP hardware is now recognized by the powercom driver. 1503 This change may also support other KIN-xxxxAP equipment. 1504 [Preston A. Elder] 1505 1506 - The 1.1kVA UPS is now supported by the bestuferrups driver. This 1507 driver was also changed to allow easy addition of more models 1508 in the future. 1509 [Bob Apodaca] 1510 1511 - The fentonups driver can now handle devices which implement the 1512 "I" detection differently, and now supports the Giant/WELI 500 1513 as a result. 1514 [Joon Guillen] 1515 1516 - The serial number of the UPS being monitored can now be specified 1517 with serial= in ups.conf in the genericups driver. 1518 [Shaul Karl] 1519 1520 - The newapc driver now sends ESC to break out of menus when the 1521 initial detection fails. Some new APC models have interactive menus 1522 on the serial port, and the driver couldn't handle them before. 1523 1524 - The snmp-ups driver now reports ambient temperature and humidity 1525 data for APC equipment. It also now supports the shutdown.reboot and 1526 shutdown.reboot.graceful commands. 1527 [Dmitry Frolov] 1528 1529 - The list of supported variables and commands in the snmp-ups driver 1530 has been expanded. 1531 [Arnaud Quette, J.W. Hoogervorst] 1532 1533 - Various drivers now report bypass mode with the BYP status word. 1534 [Arnaud Quette] 1535 1536 - Energy Sistem equipment is now supported with the esupssmart driver. 1537 [Antonio Trujillo Coronado] 1538 1539 - The Tripp-Lite SU series (SmartOnline) is supported with the new 1540 tripplitesu driver. 1541 [Allan Hessenflow] 1542 1543 - The HP PowerTrust A2994A is now recognized by the hp driver. 1544 [Jan Sporbeck] 1545 1546 - Many drivers were cleaned up to perform basic sanity checks on the 1547 status data before using it. 1548 1549 - An explicit cleanup function has been added to the driver core to 1550 ensure that all dynamic resources are freed before exiting. This 1551 is part of the larger process to check for memory leaks and other 1552 bad things. 1553 [Arnaud Quette] 1554 1555 - upsd now provides variable descriptions from an auxiliary file. 1556 This file is optional, which allows for a smaller memory footprint. 1557 It can also be edited for localization or other customizations. 1558 1559 - upsimage and upsstats can now render BATTVOLT data. 1560 [Andrew R. Ghali] 1561 1562 - String handling has been cleaned up throughout the tree. Calls to 1563 functions like strcpy and strcat were either replaced with other 1564 (range-checking) functions or were rewritten to avoid it. 1565 1566 - Many compile-time defaults may now be overridden at runtime. In 1567 the environment NUT_CONFPATH and NUT_STATEPATH may be used. 1568 upsdrvctl has been changed to execve to pass these along to the 1569 drivers. ups.conf now supports driverpath=, and upsd.conf supports 1570 DATAPATH. 1571 [Bryan Henderson] 1572 1573 - The configure --with-gd switches now actually do something useful 1574 when gd has been installed outside the default search directories. 1575 [Patrik Schindler] 1576 1577 - The inline keyword is now handled properly on systems which do not 1578 support it or have it specified as another name. This was breaking 1579 compiles on some systems. 1580 [Petter Reinholdtsen] 1581 1582--------------------------------------------------------------------------- 1583Release notes for NUT 1.2.2 - what's new since 1.2.1: 1584 1585 - The snmp-ups driver has been upgraded and expanded. It now supports 1586 multiple MIBs, meaning it can handle RFC 1628, APCC, and MGE 1587 equipment. You can pick the right one with "mibs=" in ups.conf. 1588 1589 Support for setting variable and instant commands is also available. 1590 [Arnaud Quette and Dmitry Frolov] 1591 1592 - The powernet driver has been upgraded. It now supports more 1593 variables, has cleaner logging, and may now be considered stable. 1594 [Dmitry Frolov] 1595 1596 - The hidups driver now supports physical port IDs. This avoids most 1597 of the problems where the hiddev* names can jump around too easily. 1598 It will now stay in the same place as long as you keep it plugged 1599 into the same physical port. See the ChangeLog file for more details. 1600 [David Brownell] 1601 1602 - The hidups driver now also supports the MFR variable on APC 1603 Back-UPS ES equipment. 1604 [Jonathan A. Davis] 1605 1606 - The sms driver has been updated to version 0.70. 1607 [Marcio Gomes] 1608 1609 - The bestups driver now recognizes Best Power Axxium Rackmount 1610 equipment. 1611 [Ales Casar] 1612 1613 - The liebert driver now uses O_NONBLOCK, and should now work 1614 consistently on OpenBSD as a result. 1615 [Alex Cichowski] 1616 1617 - The liebert driver also now uses debouncing logic on the status 1618 lines. It was possible to get false readings that would start a 1619 shutdown or just annoy users with excessive onbatt/online notify 1620 messages. The new code forces the status to settle down for 3 polls 1621 before accepting the new value. 1622 1623 This means that very short power events may not be detected. The 1624 alternative is having your machine shut down just because it decided 1625 to wiggle over to OB LB for a few seconds. 1626 1627 - upsmon has had the disconnect logic fixed so the "communications 1628 lost" (COMMBAD) notify will actually go out when the connection 1629 fails. 1630 [Steve Monett] 1631 1632 - upssched now uses a lock file to prevent a race where two could 1633 start at the same time. The second upssched would "win", and the 1634 first one would be unreachable. This had the side-effect of not 1635 being able to cancel timers on the first one. 1636 1637 If you use upssched, you must define the LOCKFN directive when 1638 upgrading to this version, or it will not work. 1639 [Gaspar Bakos] 1640 1641 - The packaging and scripts for Red Hat systems have been updated. 1642 [Antonino Albanese] 1643 1644 - upsd is now a bit more lenient about access levels in the 1645 'numlogins' check, which is what caused the problem in upsmon 1646 (next item). 1647 1648 - upsmon no longer gets stuck in slavesync() when upsd is configured 1649 to drop certain queries. This usually happened at the worst 1650 possible time: in the middle of a shutdown. 1651 [John David Garza] 1652 1653 - The upsclient functions now do more sanity checking on data from 1654 upsd so a short read won't return garbage to the callers. 1655 1656 - upsset now works properly with ENUM/VARTYPE values for multiple 1657 UPSes on a single upsd. 1658 [Dmitry Frolov] 1659 1660 - Various portability fixes for building on SGI were applied. 1661 [Andrea Suatoni] 1662 1663 - upsd no longer tries to reference a deleted client structure if the 1664 client disconnects at the wrong time. Previously, it tried to use 1665 that pointer after the sendback() function had already failed on 1666 write and deleted the client. This could cause upsd to segfault 1667 depending on what areas were accessed. 1668 [Patrik Schindler] 1669 1670--------------------------------------------------------------------------- 1671 1672Release notes for NUT 1.2.1 - what's new since 1.2.0: 1673 1674 - The sms driver is back, with support for Microlink Manager III 1675 hardware. [Marcio Gomes] 1676 1677 - Fideltronik Ares Series hardware is now supported as genericups type 1678 19. [Tomek Orzechowski and Arkadiusz Mikiewicz] 1679 1680 - The drivers no longer silently drop instant commands or set commands 1681 from upsd that happen to get fragmented in transit. 1682 [linux@horizon.com] 1683 1684 - The old multilink driver is back with a new name: liebert. It 1685 supports Liebert UPStation GXE hardware with the contact-closure 1686 cable. This is currently an experimental driver as there is no 1687 way to power down the load. 1688 1689 - configure now picks up the right flags for gd automatically if gd 1690 2.0.8 or higher is installed. This greatly simplifies the CGI build 1691 process for most users. 1692 1693 - Shutdowns on FreeBSD using the genericups driver should work again. 1694 [Petri Riihikallio] 1695 1696--------------------------------------------------------------------------- 1697
