Hey there! This is the first hotfix of v0.20. @nivex discovered a nasty bug in the peppermint.josn access checker - which this release fixes. If the previous releases didn't work for you, try this one.
Note that this release does not include any of the changes that are scheduled for the v0.21 release. If you want those, you should build your own from master according to the docs (or get in touch - I'm happy to send you a prebuilt copy!).
Changes in v0.21 that will be coming at some point include watchlists, email verification, performance improvements for wikis with lots of pages, and more! If you're looking to help out with that, please do get in touch if you know of a good fuzzy hash implementation in PHP for nearest-neighbour search. I'd really appreciate it :P
Anyway, updating is as simple as updating your local index.php - grab your copy from this release, or any other documented method (e.g. the downloader).
Edit: Click here to say hi if you've downloaded this release :D
