Capcom has release a small patch for Marvel Vs Capcom 3 which, according to reports, introduces a number of tweaks and changes to the game's fighters and clears up a few glitches.
Apparently, Sentinel's health has been reduced from 1.3 million units to 905 thousand (that's a lot, according to some hardcore fans).
Spencer and Haggar have also seen changes, with their freezing issue fixed and Spencer's combo loop removed. Akuma's infinite combo has also been fixed.
The patch also apparently prepares the game for a new 'Event mode' coming soon. More in-depth info via the source link.
Capcom last week launched the Jill Valentine and Shuma Gorath DLC packs.
