HOWTO_RELEASE

1. Verify that the versions currently set (see 10 and 11 below) make
   sense for this release.

2. Run 'make distcheck', fix any problem with it.

3. Update the NEWS file (extract most important things from the
   repository log). Make sure to update the release date

4. Commit the changes in the NEWS file.

5. Tag the release:
   $ git tag MAJOR.MINOR.PATCH

6. Run 'make dist-bzip2'.
   $ ./autogen.sh && ./configure && make dist-bzip2

7. Verify that you can unpack and build the tarball

8. Copy the tarball to upload.osgeo.org:/osgeo/download/geos

9. Increment all the version numbers for the next release, as below.

10. Increment CAPI_INTERFACE_X in configure.ac
    - For a release with no interface changes just bump REVISION.
      [ Even if *nothing* changed in CAPI ]
    - Adding interfaces, bump CURRENT/AGE, set REVISION to 0.
    - Deleting interfaces / compatibility issues - bump CURRENT, others to zero
      [ THIS MUST BE CAREFULLY AVOIDED ]

    - In configure.ac
    - In include/geos/version.h.vc
    - In capi/geos_c.h.in
      - VERSION_PATCH for bugfixes/improvements (even breaking C++ API)
      - VERSION_MINOR for NEW interfaces in the C lib
      - VERSION_MAJOR for SUBSTANTIAL additions or C lib ABI break
        [ THIS MUST BE CAREFULLY AVOIDED ]
    - In main CMakeLists.txt main one
       - On section: "# Set GEOS project"
         - CHANGE the line: project(GEOS VERSION <mayor>.<minor>.<micro> LANGUAGES C CXX)
         - CHANGE the line: SET(GEOS_PATCH_WORD "dev")

12. Update wiki page https://trac.osgeo.org/geos/ at Download section
