🧪 new features
- new option --redup (global or volflag) to convert local files between various dedup approaches fd4f4341 22915902 16a3f5d5
- turn full copies into reflinks/symlinks/hardlinks or convert between those
- run it with --redup-dry (dryrun) to check for unexpected consequences
- WARNING: maybe take a snapshot of your filesystem before enabling this; brand new code with little testing, read --help-redup and use with care
- the feature is currently being stress-tested; results on tuesday
- #1643 textfile-viewer can detect filetype from shebang (thx @botahamec!) 097b8305
- when dedup with reflink is enabled, then also dedup between volumes when possible (since reflink makes that safe) 735d6e00 5ddbce31
- option -i no to launch copyparty without the webserver, for indexing / testing / whatever c92435c2
🩹 bugfixes
- if --dedup was enabled, then copying a file from one volume to another could dedup (create a symlink/hardlink/reflink) instead of a full copy 947d73ee
- mainly an issue for portable storage such as flashdrives, and the main reason why --redup was added
- the list of filenames given as input to xiu hooks did not have a trailing newline c688bb2e

🧪 new features
- iPhone: new bug in iOS breaks uploading; add workaround 3ea671ff
- apple broke XHR/fetch in a recent iOS version by introducing some wtf race-conditions in response handling; under high network load, the browser simply forgets to tell js that there's a response, so we're basically flying blind
- this workaround makes iOS uploads 50x faster than before but still not perfect (impossible given the situation); will be stuttery until apple fixes iOS
- apple will probably fix it very soon given the severity of the bug, but at least one copyparty user is forever-stuck on iOS-18.x which will never be fixed by apple, so a workaround is justified
- #1617 new plugin to thumbnail office documents with collabora (thx @kamaeff!) d4a1ce48

- btrfs-specific: nocow .hist to improve sqlite performance dd9cf645
🩹 bugfixes
- two low-severity vulns in different components, but surprisingly similar synopses:
- GHSA-mc69-pxc8-4xf4 dirkeys (volflag dk) did not prevent descending into subdirs if an attacker could guess the name of the subdir 55969b8e
- GHSA-3fhv-rhjw-7hrg sftp did not fully enforce volflags xvol/xdev; an attacker could read a file inside the symlink destination if they could guess the name inside b80a210e
- not important enough to be listed in "recent important news", but will be detected by the (default-disabled) version-checker

- wopi: option --wopi-accs to limit who's able to use the feature 78a4ee49

- new option --allow-svg-js if you really want that 566de65f
- shares: harden single-file shares some more 21c2c728 9ff6a71a
- just removing footguns (motivated by a bug-report that was a false-positive)
- copyparty.exe: upgrade to python 3.14.7 from 3.13.14 8b6e8972
- larger and slightly faster (compensated for the size bloat by making the text-image-generator more shitty)
🌠 fun facts
- the thumbex example is also a cool example how relevant the "pseudo" in PRNG can be; with random.randrange instead of os.urandom, first run followed by restarting copyparty and another run...heh

🔧 other changes
- #1552 #1551 default-disabled the bwrap ffmpeg sandbox; 85a8cc99
- sandboxing can fail in too many creative ways (funky linux distros with funky filesystem layouts and policies) so autoconfiguring bwrap is not feasible

- see the default th-bwrap value in --help on your server for a best-effort guess
- always rotate (never overwrite) -lo logfiles on startup unless --rlo no 29e145f5

- config-files can now use OS environment-variables anywhere in the [global] config section cbd82b65 e52bbed8
- by default, only the syntax ${VAR} is supported, not $VAR or %VAR%
- previously, a small handful of global-options already supported this (c lo hist dbpath ssl_log), but they also supported the $VAR syntax, which is no longer the case
- if the old $VAR syntax is detected, copyparty will crash on startup, suggesting the following remedies (choose one!) in the log:
1. update the config-value to the new ${VAR} syntax (recommended)
2. allow the old syntax with global-option --env-expand 1 (risky)
3. ignore the old syntax and only expand the new syntax with global-option --env-expand 2
4. disable all environment-variable expansions with PRTY_NO_ENVEXPAND=1

- make it even more obvious that --allow-csrf is a bad idea 9a724b01
- mention --urlform get to disable message-to-serverlog ac05b4f1
- readme: improve shadowing phrasing 003c68d0
- devnotes: explain the vendored dependencies 971f8ef9
🌠 fun facts
- this release includes code written at abs(unit)
- btw that pdp had an IPv6 lease and browsed the internet :^)
- hasn't connected to copyparty though (yet...)
- this release was powered by 一体いつから (TaKo Hardcore bootleg) followed by Fighting My Way (YUPPUN Hardcore Remix) (shd is a good dj)

- v1.20.9 (2025-02-25) fixed CVE-2026-27948 (XSS)
🧪 new features
- #1351 add .hidden support (thx @NecRaul!) beb634dc 134e378e
- cosmetic filter to exclude specific files from directory listings by adding their filenames to a textfile named .hidden similar to many linux desktop file managers
- the files are still easily available from various APIs; this is not a security feature, just a way to keep things neat and tidy
- #1381 thumbnail pregeneration 7d6b037d
- usually/generally not a good idea; readme explains it
- shares: now possible to grant the . permission to see dotfiles 66f9c950
🩹 bugfixes
- #1372 #1333 no thumbnails if the server OS was too old to have JXL support and the webbrowser was asking for JXL 1afe48b8
- #1363 new-version alert would only appear if the visitor had the Admin permission in the webroot specifically; now A in any volume is sufficient 6eb4f0ad
- 66f1ef63 should have blocked mkdir too and now it does (thx @restriction!) ac60a1da
- setting the nohtml or noscript volflags on the webroot would break the web-UI eb028c92
- shares: the -ed global-option did not make dotfiles visible in shares 66f9c950
- the dots volflag still doesn't, but that one is intentional
🔧 other changes
- tried to stop libvips from gobbling up obscene amounts of ram while creating jxl thumbnails abdbd69a
- libvips is now default-disabled unless the libc is musl and the allocator is mallocng, which means alpine linux, which means the docker image with mimalloc disabled
- all other deployments will now have slightly slower jxl thumbnail generation by using ffmpeg instead (it's fine really)
- new global-option --th-vips-jxl lets you force-enable it if you dare
- volflags nohtml and noscript now available as global-options --no-html and --no-script 5f3b76c8
- and the -ss paranoia option now also enables --no-html --no-readme --no-logues
- --flo 2 now removes colors from logfiles even if -q is not set 8c6d8a3c
- update dompurify to 3.3.3 6a9e6da8
- docs:
- #1360 versus.md: more readable headers (thx @eugenesvk!) e71e1900
- #1367 mention --shr-who in the readme (thx @TWhiteShadow!) 4688410f
🌠 fun facts
- it is easter soon edc20175

- GHSA-67rw-2x62-mqqm: when a share is created for just one or more files inside a folder, it was possible to use FTP or SFTP to access the other files inside that folder by guessing the filenames
- so ignore this issue if you did not enable FTP or SFTP in the server config
- it was not possible to descend into subdirectories in this manner; only the sibling files were accessible
- NOTE: this does NOT affect filekeys; this is specifically regarding the shr global-option
- password-protected shares were not affected through SFTP, only FTP
this release also fixes GHSA-rcp6-88mm-9vgf but that one is nothing to worry about

🧪 new features
- features? in this econonmy?? ain't nobody got time for that
🩹 bugfixes
- 66f1ef63547a8c5f45dc2472801d2a973ff997cc GHSA-67rw-2x62-mqqm (shares)
- 9f9d30f42c89d1d5fc79ae745f136a9d5f857192 GHSA-rcp6-88mm-9vgf (the other thing)
🌠 fun facts
- the first cve is still by far the worst, none of the others even close... so at least that's nice
- if you saw the cve notification and got all worked up, here's some comfy music to relax and upgrade copyparty to

GHSA-m6hv-x64c-27mm the nohtml volflag did not prevent javascript inside SVG images from executing -- a malicious user with write-access could upload an SVG file which would execute as javascript when someone opens it 1c9f894e
recent important news
- v1.20.9 (2025-02-25) fixed CVE-2026-27948 (XSS)
🧪 new features
- version-checker (thx @icxes!) c6965f06
- default-disabled; you must choose a URL to grab security advisories from to enable it
- periodically checks the security advisories and shows a warning in the controlpanel if you're running a vulnerable version
- can optionally panic and shutdown the server if you prefer that
- man, the timing on this though... absolute cinema
🩹 bugfixes
- fix nohtml not being aware that SVG images can execute javascript 1c9f894e
- a new volflag noscript was also added; nohtml will automatically enable noscript, but noscript can also be useful on its own; see readme
- various upload rules fixes:
- #1335 rotf couldn't handle trailing slash (thx @NecRaul!) 8e20506d
- #1337 rotn didn't always count correctly (thx @NecRaul!) 23d4a62e
- rotn didn't apply to dupes 00e821db
- combining rp-loc and site was a bit jank (thx @new-sashok724!) 31b23843
- global-option idp-store: 2 would result in excessive config reloading 1272de9d
- fix fd-leak when indexing certain compressed files, including epub books 8b5ac23e
- forget-ip: fix sqlite cursor-locking 37123e33
🔧 other changes
- #1316 Chinese translation got a huge makeover (thx @satgo1546 and @lxdlam!) b0152741
- #1324 better rclone advice on the connect-page 8941701a
- static website resources, previously served from /.cpr/ have moved to /.cpr/w/ for easier configuration of allowlists in reverseproxies and authentication middlewares 753ff548
🌠 fun facts
- according to the SVG spec, images being able to execute javascript is a feature and intentional behavior... what a concept!

- v1.20.9 (2025-02-25) fixed CVE-2026-27948 (XSS)
🩹 bugfixes
- #1311 fix login (broke in v1.20.9) ecdfd2d1
🔧 other changes
- warn that config-reload doesn't do global-options a29037a0
🌠 fun facts
- rushing out a cve-fix in the wee hours of the morning before the 9-5 is a great idea that never goes wrong
- 10/10 will probably do again

GHSA-62cr-6wp5-q43h could let an attacker execute arbitrary JS by tricking you into clicking a malicious link 31b2801f
🔧 other changes
- webdav: dav-port can be used as an alternative to daw d21242fc

- #1298 add Hungarian translation (thx @sonacl!) eefb181b f37c3b96

🩹 bugfixes
- audioplayer skip-silence:
- #1303 clamp ffwd to safe values (thx @icxes!) f5e70c7f
- fix crash on folderchange f1a433a6
🔧 other changes
- due to legal reasons, the docker-images and bootable flashdrive are now unable to create thumbnails of HEVC/h265 videos and heif/heic images 1bec91d1
- this primarily means photos/videos taken with iphones (and maybe some samsung phones)
- on the bright side, this has made the docker-images much smaller; ac is now half the size it used to be, and iv / dj are each 97 MiB smaller
🌠 fun facts
- if you wanna see your car doing its best impression of a frictionless spherical cow, I can warmly (heh) recommend the icy snowcoated countryroads of viken this weekend
- goes oddly well with sakuraburst - deconstructing nature

- now possible to upload/delete files while the filesystem-indexer is still busy d44ea245 0ca4c1bd
- global-option fika decides which actions to allow while still indexing; default is upload+copy+delete
- full deduplication is only guaranteed if this option is set blank, as dupes are allowed while indexing
- #1266 browsers can request thumbnails as jxl images (thx @intelfx!) b2711e05 720c83b2 93ffc65c a65a30b1 a7a25deb 59de5e2c 16403d8c 48c10178 0e8913c2
- the future is FINALLY here (sure took a while)
- some notes on memory/RAM usage though -- it is fine on Alpine Linux, so docker is also fine, just don't enable mimalloc
- jxl can be disabled with global-option th-no-jxl if necessary on baremetal deployments until libvips fixes this
- #1265 audioplayer can "skip silence" now (thx @icxes!) 66949989
- #1287 opensearch support for opds (thx @philips!) 84e687a0
- #1276 option to allow editing of arbitrary file-extensions with only the read+write permissions 312f48e1 d6928380
- option rw-edit is the comma-separated list of permitted extensions, default is md

- docker: add option to run an arbitrary script (for customizations and such) during startup bf01ca48
🩹 bugfixes
- #1279 the textfile-viewer would refuse to load huge documents when hotlinked f02e9cf6
- #1280 the custom rightclick-menu was enabled in the textfile viewer fc8a4b8e
- #1262 logtail now works on windows; would previously take an exclusive-lock on the monitored file, as windows does by default a368fc66
🔧 other changes
- volumes are hidden from the treeview if the name starts with a dot 76041fdb
- #1277 descript.ion files no longer require the e2d and e2t options to be enabled 4cb4e820
- chunked PUT-uploads are now terminated if they exceed a configured size limit dfadb5a7
- #1282 improved compatibility with GraalPy (thx @vgskye!) e8609b87
- #1292 #1296 updated Esperanto translation (thx @slashdevslashurandom!) 418bf2f9 914f84ce
- thumbnails: use libvips as fallback for rawpy 27ae2e1e
- libvips doesn't support .arw files (sony) yet, so still need rawpy
- make server config slightly easier:
- improve xff warnings 96aeb898
- warn if config-values are quoted 598df44e
- lowercase headernames in configs fd096385
🌠 fun facts
- the fika option sends the filesystem-indexer on a coffee break
- exci wants me to mention aoi yuuki here for some reason :^) so here's gekisou gungnir

- #1264 now possible to grant the get permission when creating a share 95b827f1
- the button was already there, but until now it did nothing
🩹 bugfixes
- a safeguard (24141b49) added in v1.20.5 was too strict and would block requests from certain reverseproxies, specifically anything that adds X-Forwarded-HTTP-Version 72224d29

- #1240 webdav clients can now set fractional last-modified timestamps (thx @jcwillox!) 296362fc
- #1260 add support for running the server with GraalPy (thx @vgskye!) 73d06eaf
- #1182 pressing CTRL-C will copy links of selected files to clipboard 9c14972d
🩹 bugfixes
- #1248 shares: fix the buttons for extending expiration time b6bf6d5f
- #1242 webdav: fix «MacOS Finder» taking forever to connect (thx @freddyheppell!) 8e046fb6
- ie11 would spinlock in write-only folders 5c4ba376
🔧 other changes
- fast again! ed6a8d5a
- replaced the connection:close band-aid added in v1.20.4 with a proper fix that doesn't make things slower behind reverseproxies
- I've tried everything I can think of (with nginx as reverseproxy) and can't notice any difference in behavior, but please let me know if this breaks anything for you 🙏
- #1245 updated Portuguese translation (thx @000yesnt!) 69fa1d10
- #1259 OpenRC: add command to test config (thx @lotsospaghetti!) 79273a7d
- #1257 removed the nth global-option because it was never implemented (thx @stackxp!) 22cdc0f8
- syntax highlighter: added languages nasm + nix, removed autohotkey + cmake b20d3259
🌠 fun facts
- http/1.1 still tends to be faster than http/2 and http/3 for large transfers which is the main reason copyparty hasn't made the change
- eh, not really a fun fact I suppose ┐( ´ w `)┌

- #1235 rightclick-menu: fix creating new files/folders in gridview (thx @SpaceXCheeseWheel!) ffca67f2
🔧 other changes
- #1229 updated the Esperanto translation (thx @slashdevslashurandom!) 1142ac25
- #1232 shares: if an external domain is configured, then show both the LAN and external link for each share 81e5eb7b
- #1231 when reverse-proxied, always connection:close (don't reuse tcp/uds connections) e1eff216 b4fddbc3
- ^ was a nice reminder to not take every hint from the reverseproxy at face value, and a fresh socket for each request might help avoid such issues altogether
- the expected performance impact from this change is near-zero for real use, even if benchmarks confirm a 50% drop in requests/sec in the absolute-worst-case (burst of cheap requests)

- send-message-to-serverlog now also available as url-parameter ?smsg=foo
- option smsg configures which HTTP-methods to allow; can be set to GET,POST but default is only POST because GET is dangerous (CSRF)
🩹 bugfixes
- #1227 dillo was not able to login because dillo is more standards-compliant than every other browser (nice)
- a web-scraper which got banned for making malicious requests could remain banned for one request longer than intended (wait why did I fix this) ba67b279463530742cd7f1f1adcb738e66dad8aa
- ?ls was still a bit jank 0a3a80725aecc9303782cdbf8afcfc12937b7c1d
🌠 fun facts
- this 6AM release was powered by void/mournfinale
- was going to name the release "dilla på dillo" but somehow google-translate thinks that means "fuck on fuck" which would have been inappropriate

- read-only demo server at https://a.ocv.me/pub/demo/
- docker image ╱ similar software ╱ client testbed
