I figured that would go wrong. Frankly, I find this stuff super confusing. I followed this guide:
https://www.gnu.org/software/libtool/manual/html_node/Updating-version-info.html which says
that current should be incremented if an "interface" have been added, removed or updated. Check,
we’ve added a new function to proj.h and several things are updated. When that is the case, revision
should be reset.  It also says that age should be incremented if an "interface" has been added,
which it has. At least in the way that I have interpreted the term “interface” but I guess I am wrong
in my interpretation.

Following that had me at 14:0:2. I could use a guide that explains that stuff in a simpler way :-)

I’ll issue RC2 soon with updated libtool version. Thanks for catching this.

Tested against GDAL regression test suite and everything is OK

... but I think there's an issue with the libtool versioning

proj 5.0.0 was -version-info 13:0:0 ==> libproj.so.13.0.0
proj 5.0.01 was  -version-info 13:1:0 ==> libproj.so.13.0.1

So I think proj 5.1.0 should be -version-info 14:0:1 to generate

Currently -version-info 14:0:2 generates a libproj.so.12.2.0 which would
appear as older than the proj 5.0.x releases.



I have prepared the first release candidate for PROJ 5.1.0. This release
comes with both bug fixes as new features. Please test it on your system
and report back any problems you may find. The final release is set to
release on June 1st, assuming that a release candidate can be promoted to
final version before that. If everything goes to plan, I will call the vote
for promotion on May 30.
