The BBcode syntax for SpriteFont now must be standards-compliant with CSS colors, which require a # sign for hex values. The old support was non-standard and also deviated from the Text object which never supported that. So while it's technically a breaking change we left it as-is to keep it consistent with CSS and Text.
Setting an animation frame now accepts a string for a tag of an animation frame, so if you pass it a string it will try to look up a frame by tag now. I guess that's another breaking change technically, but I think it should be rare and easy to work around, and it's an important change for supporting tags.
This all makes sense, it just wasn't fun to open up a project where things weren't working as expected without understanding there may have been some impact with this latest update.
