One of the fixes includes a tweak to the launcher supporting more than 50 subscribed mods, or if an author removed it. There are gameplay bug issues too. It’s just a beta.
The patch is yet to be officially finished as this is a beta. Bethesda has learnt it’s better to get users themselves to try out fixes before a full rollout to avoid game breaking mistakes.
Below is the PC Skyrim changelog for patch 1.4.26:

•Fixed issue with downloading mods when you are subscribed to more than 50 mods
•Fixed crash when loading a subscribed mod that has been removed from Workshop by the author

•Fixed several issues with remapping buttons while using an Xbox 360 controller
