Rockstar has issued surprise updates to LA Noire and Max Payne 3 on PC, throwing in all the DLC for free.
Both games have also seen support for 32-bit operating systems "deprecated". Of note: the LA Noire changes do not apply to LA Noire: The VR Case Files versions of the game.
These updates were quietly issued yesterday, 19th April - the same day Rockstar somehow managed to delist its entire PC catalogue on Steam before relisting it again (Midnight Club 2 was briefly available to buy for the first time in three years). Perhaps someone somewhere at Rockstar fell on a load of PC publishing buttons or something?
