* latest gzip edition of the sfx is [v0.11.18](https://github.com/9001/copyparty/releases/tag/v0.11.18)

new features
* faster http replies! reduced the time to establish new connections, so:
* up to 25% faster round-trip time on short http requests with `-j1` (server-default), but more importantly...
* up to 3.3x faster with `-j4` (now almost equal to `-j1`) and a single client doing stuff, but wait it gets better:
* up to 6.6x faster with `-j4` and multiple clients hammering the server
* but note that higher `-j` values adds more connection latency in exchange for processing power, https://en.wikipedia.org/wiki/Thundering_herd_problem
* discard log messages early when `-q` is set without `-lo`, giving better multiprocessing performance

bugfixes
* fix general loss of centos7 support (TLnote: early 2.7 versions) introduced in [v0.11.30](https://github.com/9001/copyparty/releases/tag/v0.11.30)
* also fixed downloading folders as zip-files which centos7 never could

other changes
* `-j1` will be forced for python 2.7 because it cannot pickle tcp servers
* accessing `?stack` works on any url as long as you're admin *somewhere*
* the `-j` loadbalancer messages are gone because the loadbalancer is gone
* should give a teeny-tiny performance boost to multiprocessing on uploads

bugfixes

* latest gzip edition of the sfx is [v0.11.18](https://github.com/9001/copyparty/releases/tag/v0.11.18)

new features
* `turbo button` in the settings panel for superfast resume of massive uploads
* good for when you were in the middle of uploading 100'000 files and had to restart for some reason
* comes at a serious cost: files will be skipped as long as they exist on the server with the right filesize, even if they could be incomplete uploads or are otherwise different from your local files, so you should do a "verification pass" by disabling turbo + refreshing + redoing the upload once you make it through
* when combined with the new `date-chk` button it *should* notice and resume incomplete uploads but please do the verification pass anyways
* all of this is explained in the tooltip for the button so idk why im putting it here too
* `-lo` enables xz-compressed logging to file in addition to printing to the console
* with logrotate if the filename contains date-format-strings (like `%Y-%m-%d`)
* when combined with `-q` it disables console-logging and only logs to file, gives a tiny speed boost depending on OS
* also cleans up a few places with plain prints instead of the threadsafe pretty ones
* the volume-flags summary on startup now also print *which* volume they're talking about

bugfixes
* `dir.txt` inside the thumbnails folder could be downloaded; possibly bad since it contains absolute-paths from the host filesystem
* [v0.11.31](https://github.com/9001/copyparty/releases/tag/v0.11.31) added parallel handshakes which could cause files to checksum and upload out-of-order, fixed
* this also uncovered another UI-crash in the up2k client (nice) which is now also fixed separately
* a few more cases of recursive symlinks are detected and defused
* symlink pointing to its own folder when creating a tar/zip
* initial directory scanning (`-e2ds`)
* initial directory scanning is now a tiny bit slower, sorry
* `-nw` didn't apply to PUT uploads
* more invalid requests get a sensible-ish reply stating what the client did wrong

* latest important update: [v0.11.20](https://github.com/9001/copyparty/releases/tag/v0.11.20)

* latest gzip edition of the sfx is [v0.11.18](https://github.com/9001/copyparty/releases/tag/v0.11.18)

new features
* parallel handshakes
* faster uploads and file-search, especially on tiny files / high-latency connections

bugfixes
* send keepalive handshakes when an upload has been paused / idle for 5h 45min so it doesn't expire
* fixes one of the v0.11.30 known-bugs but still no idea what that other thing was, something about "bad file descriptor" right before a power outage so the logs are lost, shoganai
* race conditions in the up2k-server which couldn't be hit before parallel handshakes was added

* latest important update: [v0.11.20](https://github.com/9001/copyparty/releases/tag/v0.11.20)

* latest gzip edition of the sfx is [v0.11.18](https://github.com/9001/copyparty/releases/tag/v0.11.18)

known bugs
* if an upload is paused by setting `parallel uploads` to `0` in the UI...
* ...for "about an hour", it *might* be unable to resume
* ...for 6 hours or more, it is **definitely** unable to resume

unless the upload was paused for 6 hours or more, it can probably be resumed by refreshing the website and restarting the upload ("probably" because haven't been able to reproduce)

new features
* up2k-client: 100x faster initialization when adding lots of files
* cachebuster to force chrome to use the correct js/css files since it ignores the no-cache header
* make `-nw` apply to more stuff (up2k skips creating files)

bugfixes
* up2k-client:
* fix crash caused by parallel uploads running far ahead, ui trying to update stuff it already purged
* mostly problematic when uploading lots of small files mixed with slightly-larger files
* general robustness
* recover from tcp/dns issues during chunk-uploads
* recover from antivirus yanking files mid-read
* ignore server complaining about duplicate chunks, it's fine
* help chrome not get stuck when it sees a file named `aux.h` on windows
* notice and panic on more errors
* and stop trying to do things after something died to an unhandled exception
* less confusing debug messages regarding sha512 library selection
