better file delete
tl;dr: Files delete from your disk better now.
For a long time, actually physically deleting a file that leaves the client's trash has been a bit hacky. To reduce UI lag, the recycle or delete action has to be deferred to the future, but since there was no permanent record of what to delete, the deferred job was always a bit rushed and in a couple of instances (e.g. if you cleared trash and closed the client soon after) it could leave file orphans behind. The system has always been fail safe, never deleting too much, but it could lead to surplus cruft in file storage. Secondly, it turns out the server never got physical file delete tech added! The file repository has never been used much, and it just never came up.
So, this week I overhauled the whole way it works. Now both client and server keep records of the files they should delete, print delete summaries to the log, use neater delete daemons that smooth out the work to be non-interrupting, have sophisticated 'is this an orphan now?' logic to ensure that edge cases are kept in storage until they are truly no longer needed, and correct themselves in odd cases (like if you re-import a file just a couple of seconds after deleting it from the trash). They are also more aware of repository update files, which is another thing neither have been good at clearing out in the past.
So, you don't have to do anything here, but with luck doing things like 'clear trash' and other large forced physical deletes should just work a bit nicer now. Users who run a server may see it clear out a couple of files after booting, and in a few weeks I'd like to roll out a 'clear orphan files' server database action for the admin menu just like the client's so you can clear out legacy files from deleted services.

- image icc:
- images with embedded icc colour metadata are now normalised (to sRGB) like the rest of media rendering in hydrus. ICC can often mean photos, where a nice camera will apply ICC data to compensate for camera defects or general lighting information, or it can mean normal digital images where the software attached extra colour data when it was saved
- the image will now be rendered with 'fixed' colours in the media viewer, and new thumbnails should be good too. it applies early in image load and should work in all cases hereon, on both client and server
- images with an ICC will take a little longer to initially load. I'd estimate 10-50ms extra for most. one user with many ICC images discovered 10% of their collection had an ICC. I don't think the delay will be terrible IRL, but see how you get on and let me know! maybe giganto patreon pngs will have a fresh surprise for us
- future expansions here will be a database cache of ICC images and system:has icc, perhaps a button to click the ICC application on and off live in the media viewer, and then maybe options to load up and switch an ICC for your display
