TouchOSC added support for MIDI System Exclusive messages and sending key-strokes and key-combinations via the TouchOSC Bridge. Be sure to head on over to TouchOSC's download section and update to the latest versions of Editor and Bridge as well!
TouchViZ added 10 blend modes and 19 new effect filters and a few new handy switches and buttons. Documentation has also been updated to reflect these changes.
TouchOSC and TouchViZ are now available together as the Touch Control and Visuals bundle on the App Store, which not only means that if you buy the bundle you get a nice discount on the price of the applications combined, but that you can also claim that very same discount when buying one of the apps if you already own the other.
Last but not least, many TouchOSC/Android users have been asking about support for cabled connections to their computers which seem to be so in vogue at the moment, and I am happy to direct you to a handy tutorial on setting up just that over on http://www.vurt.org.uk.
