Be sure to read the release announcement.

• #46: You can now specify meta tags for blog posts.
• #57: Our Database class can now connect to UNIX sockets. Set the hostname to unix:/path/to/socket.
• #65: You can now add database connections to the local database connection pool. You can also add database connection pools for app-specific purposes. In the future, we'll support more than just PostgreSQL.
• Database connections are now lazy instead of eager, which should result in less overhead on HTTP requests that don't use additional databases. (In our cabins, this affects nothing.)
• #67: Blog posts are now linked from the Bridge.
• #69: Added a dedicated log for the auto-updater.
• #70: Added a faster install option for deploying an Airship in a hurry, with the sane defaults we provide.
• #77: Fixed responsive UI/UX warts (i.e. small links and buttons).
• #80: If the GD extension isn't loaded, render QR codes for two-factor authentication as SVG instead.
• #88: The installer now uses Zxcvbn to enforce a minimum password strength for administrator accounts.
• Added more input filters for one-dimensional arrays consisting of a static type (e.g. int[] will return a one-dimensional array of integers).
• Unhandled exceptions now display a static page outside of debug mode, which is a little better for UX than a white page.
