It's bad form to reduce the allowed length of addon names and their file paths without warning.
Not to mention that the file path limit for embedded files starts from the root of the drive the user has the game installed on? So addon developers are at the mercy of the user's USERNAME on their own machine, and how long that might be. Oh, and we're also at the mercy of the physical location of the game on their system... heavens forbid they install to a lengthy folder name, or a deep nest of folders.
Once again, thoroughly unimpressed with your handling of changes. It seems normal to have unannounced, detrimental, nonsensical changes in every single patch. Are you intentionally trying to drive the rest of us away?
