a second 5.0.1 release candidate is now available:
1. several annoying bugs affecting IS NULL and IS NOT NULL clauses
on Virtual Tables (VirtualShape, VirtualDBF etc) have been fixed.
it should be noted that such bugs were present since the very
first introduction of Virtual Tables and weren't never reported.
2. the standard behavior of build options --enable-rttopo and --enable-gcp
has been inverted, and now are both enabled by default.
you can eventually disable the one and/or the other by explicitly
configuring your local build as
./configure --disable-rttopo --disable-gcp
3. updated the library SONAME
this is the expected to be the last release candidate; if no
issues will be reported in the next two days I'll go for
the final release of 5.0.1 on next Sunday.
