big changes, **bugs likely**, keep [v0.11.11](https://github.com/9001/copyparty/releases/tag/v0.11.11) as a fallback and go whine in the irc
* otherwise a drop-in upgrade; no additional steps to consider since [v0.11.1](https://github.com/9001/copyparty/releases/tag/v0.11.1)
nothing really important happened since [v0.11.6](https://github.com/9001/copyparty/releases/tag/v0.11.6); quick summary:
* [v0.11.9](https://github.com/9001/copyparty/releases/tag/v0.11.9): fix zip/tar of recursive symlinks
* [v0.11.10](https://github.com/9001/copyparty/releases/tag/v0.11.10): fix direct tls connections
* [v0.11.11](https://github.com/9001/copyparty/releases/tag/v0.11.11): fix live-rescan without a root folder
* this ver only fixes unlikely edge-cases
new features:
* folder thumbnails if they contain `folder.jpg` or `folder.png`, good for music servers
* `--hist` stores the per-volume databases and thumbnails all in one place, instead of the `.hist` subfolders in each volume
* `--no-hash` disables file hashing, good for a simple searchable index, but keep in mind it disables file-search and dupe detection
* both this and `--hist` can be adjusted per-volume with volflags, see readme
* thumbnails keep transparency
* `--th-ff-jpg` fixes video thumbnails if your FFmpeg is bad (macos)
* more info in the [admin panel](https://user-images.githubusercontent.com/241032/121763646-15422780-cb3e-11eb-8932-130af39acb48.png) (num.files queued for hashing or tags)
* `--css-browser` to set [custom CSS](https://user-images.githubusercontent.com/241032/121763647-15dabe00-cb3e-11eb-90a4-1628a072545c.png)
* use `.prologue.html` or `.epilogue.html` to do this per-folder; that allows for javascript too
* cygpaths for windows, `-v c:\users::r` and `-v /c/users::r` both work now
* extremely minor (i think) performance improvements which probably drown in the new bloat
bugfixes:
* mounting a volume deep inside another volume will no longer create additional databases, avoiding rescan of files in intermediate folders
* backwards-compat so it will continue to use any intermediate databases made by v0.11.11 or older
* better error message on basic-upload into a folder that doesn't exist / without permission
* minor race introduced in 0.11.1 which could be triggered by an upload really early after starting the server
