Some projects track milestones (with a date) on GitHub, but those dates are far from set in stone. The release planning for PROJ itself does this, and generally sticks close to the planned release dates, see: https://github.com/OSGeo/proj.4/milestones > I feel there it would be useful to community from techies to the wider > user community about: > > What is proj6. What is all the fuss about. The PROJ docs are quite good: https://proj4.org/ But as discussed on the proj list, not as actively maintained as the codebase. The major changes in PROJ, libgeotiff & GDAL are the result of the Barn Raising: https://gdalbarn.com/ > What packaging mismatches are we going to encounter during the cross > over period?

All applications should be using the version of the proj package which is in OSGeoLive. This implies waiting with the upgrade to PROJ 6.x until most applications support it, either by adopting proj.h or defining the deprecated flag. Some of the Debian packages have been updated (in git) to set the flag, but I didn't continue because some of the important packages in dependency level 1 failed to build with PROJ 6, see: https://lists.debian.org/debian-gis/2019/03/msg00004.html I'm waiting for the PROJ 6.1.0 & GDAL 2.5 releases before trying the rebuilds again. Especially the test failures in proj-rdnap are concerning as this show a major regression when using certain datum grids: https://lists.osgeo.org/pipermail/proj/2019-March/008320.html The lack of recent SpatiaLite final releases is also concerning: https://groups.google.com/d/msg/spatialite-users/eNkl3Ec8kfQ/fuLa4hHIAQAJ Kind Regards, Bas -- GPG Key ID: 4096R/6750F10AE88D4AF1 Fingerprint: 8182 DE41 7056 408D 6146 50D1 6750 F10A E88D 4AF1 _______________________________________________ osgeolive mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/osgeolive
