What’s new
Verified 2h ago> [!IMPORTANT]
> AI recently discovered an important security flaw in hydrus. If you are running v691 or earlier you should update to v692 or later, such as today's release. [Check here for more details](https://github.com/hydrusnetwork/hydrus/releases/tag/v692).
## misc
* added 'confirm add-undelete tags' to the cog icon on 'manage tags'. if you have been annoyed at the 'confirm your action' popups in the new manage tags dialog when you type in a tag that was previously deleted, please uncheck this and let me know how it feels
* added 'allowed actions for taglist double-click:' to this menu too. if you don't ever want to see a 'clear deletion record' option, or whatever, you can now turn things on and off here too
* fixed the 'clear trash' routine to delete more than one old file per run. this was the lagging logic patched last week, now improved back to what it was originally intended to do
* also made the clear 'trash routine' wait on 'a file was recently deleted' safety delay more intelligently (it doesn't work if a file was deleted in the past sixty seconds, as a grace period for undeletes of accidental giant deletes), and, lmao, it no longer sends this signal itself
