Pretty big update for GTAV/GTA Online today with Rockstar releasing title update 1.12 for both PS3 and Xbox 360 consoles. There is an absolute ton of changes, fixes, updates etc. which we'll list at the end of this post.
 
Rockstar have also announced that from now until Friday - when Capture Creator arrives - you can get double RP and GTA$ from any of the official Capture jobs currently available.

This Friday, April 11th, we'll be adding the ability to construct your own Capture Jobs with the GTA Online Creator tool. This update will let you create Jobs across any of the four Capture Job variants (Contend, GTA, Hold and Raid) and publish them for all to play, rate and share via the Rockstar Games Social Club.
In honor of this forthcoming update, and to help you hone your skills for the wave of new player-made Capture creations to come - from now until Friday, playing any of the official Capture Jobs in GTA Online will earn you twice as much GTA$ and RP. If you haven't yet played Capture Mode in GTA Online, it's a GTA twist on classic capture the flag style confrontations that brings a whole new level of adversarial action to the world of Los Santos and Blaine County. Strategy plays a huge role as you run decoys, set traps and place obstacles to ensure your enemies don’t get close to your goods.

 
Title Update 1.12
The title update, available today, has a massive change log. Highlights include:

bonus RP every time you like or dislike content after playing it, the ability to call Lester and have him instruct the cops to turn a blind eye to criminal activity for a short period of time, as well as increased payouts for completing Parachute, Races, Deathmatches and LTS Jobs with less than four players.

The full change log is far too big to list here, so if you're interested in seeing all the things that have changed, take a look at the Rockstar Support page.
