1# Please note that **rgdal** will be retired by the end of 2023, plan transition to sf/stars/terra functions using GDAL and PROJ at your earliest convenience. 2 3# Version 1.5-28 (development, rev. 1157-) 4 5* Adapting to R 4.2 Windows UCRT 6 7# Version 1.5-27 (2021-09-16, rev. 1149-1156) 8 9* Correcting logic error in check for MXE UCRT builds (temporary) 10 11# Version 1.5-26 (2021-09-15, rev. 1141-1148) 12 13* Mute use of PROJ CDN for MXE UCRT builds (temporary) 14 15* Run autoupdate on configure.ac to handle obsolete AC_HELP_STRING etc. 16 17# Version 1.5-25 (2021-09-08, rev. 1122-1140) 18 19* Add environment variable access to --with-data-copy by PROJ_GDAL_DATA_COPY (https://github.com/r-spatial/sf/issues/1605) 20 21* Adaptations for PROJ 8. 22 23* Handle mixed 2D/3D in readOGR(): (https://github.com/r-spatial/sf/issues/1683) 24 25* Add tweak for UCRT builds. 26 27* Thin examples for spTransform(). 28 29# Version 1.5-23 (2021-02-03, rev. 1120-1121) 30 31* Further fallout after removing valgrind issues. 32 33# Version 1.5-22 (2021-02-02, rev. 1106-1119) 34 35* Attempt to remove further valgrind leak in proj6.cpp: PROJcopyEPSG() and in ogr_proj.cpp, both wrongly placed object destructors. 36 37* Modified roundtripping all declared projections in ?project examples because some listed projections for PROJ >= 5 provoke valgrind leakages by returning very large out-of-scope values for input coordinates (0, 0); inversion of these is not attempted; some listed projections are not projections. 38 39# Version 1.5-21 (2021-01-27, rev. 1093-1105) 40 41* Suggest **rgeos** to write pre-SFS multipolygon objects to avoid unpleasant workaround. 42 43* Try to eliminate current valgrind leaks, starting from (https://github.com/r-spatial/gstat/issues/82). 44 45* Try to increase robustness to installation with early PROJ 6 versions, which often lack functionality found necessary later (for example visualization order); the code had assumed that this function always was available and behaved as it now does. There are now graceful failures when not available. 46 47# Version 1.5-19 (2021-01-05, rev. 1083-1092) 48 49* Dan Baston: raster speedups 50 51* PROJ 7.2.1 includes a bug-fix for `+proj=ob_tran` cases that required changes in detection and handling of target/source CRS reversal, https://lists.osgeo.org/pipermail/proj/2020-December/009999.html 52 53# Version 1.5-18 (2020-10-13, rev. 1071-1082) 54 55* condition `tests/test_enforce_xy.R` on PROJ >= 6 and GDAL >= 3 (email BDR, I forgot to re-check with PROJ-5.2.0/GDAL-2.2.4). 56 57* Adaptation to EPSG 10 database format started (from PROJ 7.2); choose DB columns by name not number in vignette. 58 59# Version 1.5-17 (2020-10-08, rev. 1051-1070) 60 61* `"CRS"` instantiation now prefers PROJ: use `rgdal::set_prefer_proj(FALSE)` to return to earlier behaviour. It seems that access from C/C++ code to mechanisms in PROJ offers more depth than going through GDAL to PROJ. This `"CRS"` instantiation in **sp** and **raster**; Proj4 and WKT2 strings may differ depending on whether instantiation is straight from PROJ or goes via GDAL. Confirmed with multiple reverse dependency checks over almost 900 CRAN packages. 62 63* By default use PROJ function to extract the source CRS from a `"BOUNDCRS"`. When `+towgs84=` is given, PROJ and GDAL see the apparent source Proj4 string as implicitly implying a coordinate operation transforming to target WGS84, leading to the WKT2 representation being a `"BOUNDCRS"`, not a `"PROJCRS"` or `"GEOGCRS"`, and thus causing misunderstandings later in searching for the most accurate coordinate operation for a transformation. May be controlled by setting the `get_source_if_boundcrs=` in `sp::CRS()` from **sp** 1.4-4 (2020-10-07). Confirmed with multiple reverse dependency checks over almost 900 CRAN packages. 64 65* Add support for instantiating from `"OGC:CRS84"` to provide a guaranteed GIS/visualization axis order WGS84 instantiator (preferred to `"EPSG:4326"`). 66 67* Permit empty string in `SRS_string=` argument to `sp::CRS()` and functions called by it. 68 69* Use GDAL `ORSIsProjected()` instead of simply looking for `"+proj=longlat"` in the Proj4 string representation where possible. 70 71# Version 1.5-16 (2020-08-07, rev. 1047-1050) 72 73* Typo in C code; use `try()` around Area-of-Interest calculation for coordinate operations (email BDR, I forgot to re-check with PROJ-5.2.0/GDAL-2.2.4). 74 75# Version 1.5-15 (2020-08-04, rev. 1020-1046) 76 77* Add support for instantiating from `"ESRI:"`. 78 79* Add Area-of-Interest to coordinate operation search (reduces the number of candidates found in many cases), and use in `rgdal::spTransform()` by default (`use_aoi=FALSE` to suppress); illustrate in vignette https://cran.r-project.org/web/packages/rgdal/vignettes/CRS_projections_transformations.html. 80 81* Harden to condition on PROJ functions only available from 6.2.0; block `"+proj=ob_tran` tests for PROJ 6.0.0-6.1.1. 82 83* Support PROJ CDN https://cdn.proj.org for on-demand download of transformation grids if requested by user; document in vignette https://cran.r-project.org/web/packages/rgdal/vignettes/CRS_projections_transformations.html. 84 85# Version 1.5-12 (2020-06-26, rev. 1007-1019) 86 87* Further corrections to `configure.ac` for older PROJ/GDAL versions 88 89# Version 1.5-10 (2020-06-09, rev. 991-1006) 90 91* Corrections to `configure.ac` for older PROJ/GDAL versions 92 93# Version 1.5-8 (2020-05-28, rev. 846-990) 94 95* Released to match **sp** 1.4.0 (2020-02-21) to 1.4-2 (2020-05-20) following months of development adapting to breaking changes in the external libraries used here: PROJ and GDAL; see also https://cran.r-project.org/web/packages/sp/news.html. 96 97* Expose `options("rgdal_show_exportToProj4_warnings"="none")` to mute Proj4 string degradation warnings. 98 99* Add new vignette https://cran.r-project.org/web/packages/rgdal/vignettes/CRS_projections_transformations.html. 100 101* CRAN Windows binary uses PROJ >= 6 and GDAL >= 3 102 103* Add PROJ-based CRS comparison: `compare_CRS()`. 104 105* `project()` and `spTransform()` use WKT2 comment if available, fallback to Proj4 representation if not. 106 107* List coordinate operations (based on pyproj code): `list_coordOps()`. 108 109* Add `enforce_xy=` arguments to try to ensure that only GIS/visualization axis order is present. 110 111* Add `"CRS"` object comment carrying WKT2 (2019) multiline string representation on read operations. 112 113* Use `"CRS"` object comment carrying WKT2 (2019) multiline string representation on write operations. 114 115# Versions 1.4-7 and 1.4-8 116 117* Fixed configure issue for R 4.0.0 118 119* Fixed length of `class()` errors for matrices becoming arrays in R 4.0.0 120 121# Version 1.4-6 (Final pre-WKT2 release) 122 123
