This release brings significant database performance improvements by using SQLite's WAL (Write-Ahead-Log) feature, resulting in far less disk I/O while writing to & deleting from the database. Previously, any changes made to the database were immediately written back to the database file (eg: mailpit.db), however now an temporary mailpit.db-wal & mailpit.db-shm file will exist alongside while Mailpit is running, which are then merged into the original mailpit.db when the program exists or during automatic pruning.
There is also a new feature (--smtp-allowed-recipients) which allows you to define (using regex) allowed recipients. All other SMTP connections will receive a 550 5.1.0 Requested action not taken: mailbox unavailable error response. This means you can run Mailpit as an open SMTP server allowing only recipients you have defined (ie: like a regular mail server). Please refer to #219 for more information.
Lastly there are a few minor big fixes to the runtime statistics visible when clicking on the "About" in the web UI.
