• Huge rewrite of the bot as it now supports sharding
• Upgraded packages, postgres in particular, which means previous versions will have to migrate their DB
• node version bumped to 14 in an attempt to fix the docker+nodejs stream bug (it didn't)
• New !!tweet flags: --noretweet, --notext and --reverse.
• !!qtprefix allows you to customize your prefix per-server
• Various bug fixes, in particular DM subscriptions being sanitized (woops) and the --ping flag.
• Allow people to request tweet counts of over 200 (and actually post more than 200 this time)
• Docker hub integration
• Fixed the !!tweetid command when used on quoted tweets
• User sanity check, can be configured in the .env but in short this should make it so deleted and banned accounts are automatically deleted at boot now and don't take up subscriptions.
