**this release will discard and rebuild your database** (`.hist/up2k.db`)
* no actions necessary, it just takes a while
* no additional steps to consider since [v0.11.1](https://github.com/9001/copyparty/releases/tag/v0.11.1) actually
* the old database will be backed up automatically just in case
* if you have expensive `-mtp` parsers (bpm/key) and a huge database (or a slow server), you can transfer your tags to the new db using https://github.com/9001/copyparty/tree/master/bin#dbtoolpy
reason: [v0.11.12](https://github.com/9001/copyparty/releases/tag/v0.11.12) changed the file checksum algorithm slightly, causing a mismatch between the server and client, and as a result:
* upload deduplication has been unpredictable
* filesearch could return false-negatives
new features
* much faster filesearch in chrome
* skip hidden colums in the /np text
* support cygpaths when pointing to mtag tools
bugfixes
* uploading folders through the up2k client would fail if the folder already existed on the server; now they merge
* change up2k hashlen to 33 bytes / 44 chars (mod24 bits) to fit base64 better, avoiding any padding bugs
* prefer client IP rater than proxy IP as fallback value when `--rproxy` is configured out of bounds
* correct indexing of files with names containing backslash on linux/macos
other notes
* the latest gzip edition of the sfx is [v0.11.18](https://github.com/9001/copyparty/releases/tag/v0.11.18)
