Part 3 will bring Postgres 9.4, a major update. Sometime in the coming week or so, while I look at new features and test the upgrade process.
PROJ 4.9.1 is the main update in the frameworks. I also updated to SQLite3 126.96.36.199. And finally I updated Shapely in the GEOS framework, and refreshed the GEOS build. (This takes care of the last Snow Leopard remnants, all maintained frameworks are now Lion minimum.)
I haven't used GRASS in years. QGIS is my tool now, and where I work.
So, I won't be packaging GRASS any more, starting with GRASS 7. Check the GRASS website for other sources of Mac packages, Michael Barton will be doing the standard Mac packages.
I may package 6.4.5 when it is released.
I will still bundle GRASS in QGIS for use by QGIS.
