1Version 2.20 --> 2.21
2
3* Upgraded code from bash to version 4.3 (now uses eaccess).
4* Fixed a bug related to getgroups / sysconfig that caused Which not to see
5  more than 64 groups for a single user (thanks to Dmitry Bakshaev for finding
6  and analyzing this).
7* Build system maintenance.
8
9Version 2.19 --> 2.20
10
11* xmalloc.h included a readline header for no apparent reason. The compilation
12  failed if readline was not installed. The dependency on the readline header
13  was removed. Submitted by Tushar Teredesai.
14
15Version 2.18 --> 2.19
16
17* Upgraded code from bash to version 3.2. This DOES has influence
18  on how Which behaves under certain circumstances.
19* Support for Cygwin: Two leading slashes are now treated as
20  possibly special, because a double leading slash can have an
21  implementation-defined meaning (depending on the Operating
22  System), as is for example the case in Cygwin.
23  See http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap04.html#tag_04_11
24  This means that GNU which no longer collapses two leading slashes
25  of a path into a single slash.
26* When the environment variable HOME is not set, the home directory
27  is now read from /etc/passwd or set to '/' if no home directory
28  could be found (this now matches the tilde lib used in bash).
29* Fixed the function declaration given in README.alias
30* Added a @dircategory and @direntry to which.texi
31* Changed the license to GPLv3.
32
33Version 2.17 --> 2.18
34
35* Fixes regarding cwautomacros (maintainer build system only).
36* Improvement of 'make release' target (maintainer target).
37
38Version 2.16 --> 2.17
39
40* Add support for shells that output '{' on the same line as the
41  function name in the output of 'declare -f' (ie zsh).
42* Added support for Tandem OSS.
43* Build system now uses cwautomacros (mostly just it's autogen.sh).
44
45Version 2.15 --> 2.16
46
47* This release fixes the bug, introduced in 2.15, that files for
48  which the 'other' permission bits apply do NOT need to be readable.
49  (The confusion came from the fact that it needs to be readable
50  when it is a shell script but there is no way to find out if a
51  non-readable file is a shell script or not.)
52  The next release of bash will be using the same algorithm again,
53  and that is the only thing that really matters.  This is also the
54  algorithm that most other shells use.
55
56Version 2.14 --> 2.15
57
58* Upgraded build system to work with automake 1.7.2 and autoconf 2.57.
59* Fixed search routine to skip executables that are not executable.
60  This is NOT done by all versions of bash (which is a bug).
61  The stock bash-2.0.5b thinks it is allowed to execute a file
62  when it has the eXec bit set for our group or other, but that
63  is not the case: when we own the file, the eXec bit of the *owner*
64  must be set and the group/other bits are irrelevant.  And when
65  we don't own the file, but the file is in our group, then only
66  the group bit matters and not the other eXec bit.  And finally,
67  when we do not own the file and the file is not in our group
68  then not only the 'other' eXec bit needs to be set, but the
69  file must be readable as well.  This has been reported to the
70  maintainer of bash.  For the rest, the search routine has been
71  copied/upgraded to that of bash version 2.0.5b.
72
73Version 2.13 --> 2.14
74
75* Upgraded build system to work with automake 1.5 and autoconf 2.53.
76* Upgraded --read-functions functionality to work with bash 2.0.5b.
77
78Version 2.12 --> 2.13
79
80* Support for shell functions.  This version also fixes the
81  problem that the alias for `which' wasn't inherited by subshells.
82  You need to change the alias by a shell function! (The rpm does
83  this automatically).
84* Fixes for the .spec file (merged changes from RedHat 7.1)
85  Now installs the which.info file as well.
86
87Version 2.11 --> 2.12
88
89* Minor man page fix (no reason to upgrade at all thus)
90
91Version 2.10 --> 2.11
92
93* Added a texinfo file (no reason to upgrade at all thus)
94  `info' is the prefered format for documenting GNU tools.
95
96Version 2.9 --> 2.10
97
98* Buildsystem fixes (no reason to upgrade at all thus):
99  Used the correct order of calling the automake/conf utils,
100  fixed my E-mail address and added a Source: line to the rpm spec.
101
102Version 2.8 --> 2.9
103
104* Fixed compile problem in Solaris 5.6 using cc
105* Added a `--help' option
106* RPMs now add a /etc/profile.d script, automatically setting a useful alias
107
108Version 2.7 --> 2.8
109
110* aclocal.m4 was missing from the tar, resulting in
111  a build failure if autoconf isn't installed.
112
113Version 2.6 --> 2.7
114
115* Support for aliases
116* Configure/compile fix in the `tilde' directory.
117
118Version 2.5 --> 2.6
119
120* Doesn't depend on libreadline.a anymore.
121
122Version 2.4 --> 2.5
123
124* Fixed which-2.spec
125* RPMs are now available from http://www.xs4all.nl/~carlo17/which
