Ghost 0.5 was a landmark release, with large parts of the software almost entirely re-written. Inevitably with such a large release, we left a few bugs in. [Ghost 0.5.1](https://github.com/TryGhost/Ghost/releases/tag/0.5.1?ref=ghost.org) contains fixes for those bugs that interfered with your ability to use Ghost's features.

Here's what's new:

- **\[Fixed\]** Casper not working in IE
- **\[Fixed\]** Cannot delete users on MySQL
- **\[Fixed\]** Lost work if logged out while editing
- **\[Fixed\]** Possible to downgrade Owner user
- **\[Fixed\]** If author changes post author they lose access to post
- **\[Fixed\]** Weird status code when authorising
- **\[Fixed\]** Errors when uppercase used in /ghost/ URL
- **\[Fixed\]** UUID validation error when importing
- **\[Fixed\]** No notification for errors when sending mail
