[geos-devel] Next GEOS release

[strk at refractions.net]

Another option would be releasing the 2.2.0 version
with a C++ library ABI-compatible with previous (versioned 2.2.0)
but with the addition of the C-API wrapper and the WKB I/O classes.

In this case users will be able to link to the C-API wrapper
and successive release (3.0.0) won't require a rebuild for them.
