Talking of release timing, I have made several changes in the MITAB 
library since the last update of the OGR copy of MITAB (currently MITAB 
1.5.1) and was wondering when would be the best time to sync the OGR 
copy. Is a stable release of GDAL/OGR a good time to upgrade the MITAB 
driver to a new version that includes new features or should that be 
done only in trunk?

I'm about to release MITAB 1.6.1 and the changes since 1.5.1 are more 
than bug fixes, one of the changes is a complete rework of the way the 
spatial index is generated. There are also a few important fixes to the 
collection code that was introduced in MITAB 1.5.1, i.e. the current 
OGR-MITAB based on 1.5.1 may produce corrupt files when writing collections.

I think it is relatively safe and would be beneficial to update the 
MITAB driver in the stable branch for this release of GDAL, but before 
upgrading the driver I wanted to find out what was the PSC's opinion 
about making non-trivial changes inside drivers in the stable branch.
