+# 2023-0923-1215  `v1.9.6`  configurable x-forwarded-for
+
+## new features
+* rudimentary support for jython and graalpy, and directory tree sidebar in internet explorer 9 through 11, and firefox 10
+  * all older browsers (ie4, ie6, ie8, Netscape) get basic html instead
+* #35 adds a [hook](https://github.com/9001/copyparty/blob/hovudstraum/bin/hooks/msg-log.py) which extends the message-to-serverlog feature so it writes the message to a textfile on the server
+  * could theoretically be extended into a [full instant-messaging feature](https://github.com/9001/copyparty/blob/hovudstraum/srv/chat.md) but that's silly, [nobody would do that](https://ocv.me/stuff/cchat.webm)
+    * [r0c is much better](https://github.com/9001/r0c) than this joke
+
+## bugfixes
+* 163e3fce46122d64bf824762b6733ff2c3551ba5 the `x-forwarded-for` header was ignored if the nearest reverse-proxy is not asking from 127.0.0.1, which broke client IPs in containerized deployments
+  * the serverlog will now explain how to trust the reverse-proxy to provide client IPs, but basically,
+  * `--xff-hdr` specifies which header to read the client's real ip from
+  * `--xff-src` is an allowlist of IP-addresses to trust that header from
+* a62f744a187bc9f821b540e8bb4e0b9a67bd01c8 if copyparty was started while an external HDD was not connected, and that volume's index was stored elsewhere, then the index would get wiped (since all the files are gone)
+* 3b8f66c0d5c27a68841814ec06f1758f146a5ff5 javascript could crash while uploading from a very unreliable internet connection
+
+## other changes
+* copyparty.exe: updated pillow to 10.0.1 which fixes the webp cve
+* alpine, which the docker images are based on, turns out to be fairly slow -- currently working on a new docker image (probably fedora-based) which will be 30% faster at analyzing multimedia files and in general 20% faster on average

+
+[happy 9/9!](https://safebooru.org/index.php?page=post&s=view&id=4027419)
+
+## new features
+* new permission `h` disables directory listing (so works like `g`) except it redirects to the folder's index.html instead of 404
+  * index.html is accessible by anyone with `h` even if filekeys are enabled
+  * well suited for running a shared-webhosting gig (thx kipu) especially now that the...
+* markdown editor can now be used on non-markdown files if account has `w`rite and `d`elete
+  * hotkey `e` to edit a textfile while it's open in the textfile viewer
+* SMB: account permissions now work fully as intended, thanks to impacket 0.11
+  * but enabling `--smb` is still strongly discouraged as it's a massive security hazard
+* download-as-zip can be 2.5x faster on tiny files, at least 15% faster in general
+* download folders as pax-format tarfiles with `?tar=pax` or `?tar=pax,xz:9`
+
+## bugfixes
+* 422-autoban accidentally triggered when uploading lots of duplicate files (thx hiem!)
+* `--css-browser` and `--js-browser` now accepts URLs with cache directives
+  * `--css-browser=/the.css?cache=600` (seconds) or `--js-browser=/.res/the.js?cache=i` (7 days)
+* SMB: avoid windows freaking out and disconnecting if it hits an offline volume
+* hotkey shift-r to rotate pictures counter-clockwise didn't do anything
+* hacker theme wasn't hacker enough (everything is monospace now)

+# 2023-0902-0018  `v1.9.4`  yes symlink times
+
+hello! it's been a while, an entire day even...
+
+## new features
+* download folder as tar.gz, tar.bz2, tar.xz
+  * single-threaded, so extremely slow, but nice for easily compressed data or challenged networks
+  * append `?tar=gz`, `?tar=bz2` or `?tar=xz` to a folder URL to do it
+  * default compression levels are gz:3, bz2:2, xz:1; override with `?tar=gz:9`
+
+# bugfixes
+* c1efd227b7377144a5760bc6cff64f4e87b626d9 symlink-deduplicated files got indexed with the wrong last-modified timestamp
+  * mostly inconsequential; would cause the dupe's uploader-ip to be forgotten on the next server restart since it would reindex to "fix" the timestamp
+* when linking [a search query](https://a.ocv.me/pub/#q=tags%20like%20soundsho*) it loads the results faster
+
+# other changes
+* update readme to mention that iPhones and iPads dislike the preload feature and respond by glitching the audio a bit when a song is exactly 20 seconds away from ending and yet how it's probably a bad idea to disable preloading since i bet it's load-bearing against other iOS bugs
+  * speaking of iPhones and iPads, the [previous version](https://github.com/9001/copyparty/releases/tag/v1.9.3) should have fixed album playback on those
