There wasn't an official changelog released for v0.14, and probably won't be. There's not really much changed, given that you just have more content added. Given the details from this post, could we update the OP to have it be something like this? (I propose this to cut down on future questions about what changed in v0.14. If an official changelog for this version gets released, we could always use it later instead.)
v0.14
**NO NEW STORY PROGRESS**
Ms. Anna – Story mode added. Gives more content to make the game feel less grindy, with new scenes of Ms. Anna added.
Existing saves – Keep using your current saves; no reason to redo any current progress. If you have a current save, access story mode from Bobby's computer. You can also start the mode from the main menu.
