there is a discord server with an @everyone in case of future important updates, such as vulnerabilities (most recently 2025-09-07)

recent important news

• v1.19.8 (2025-09-07) fixed CVE-2025-58753 (a missing permission-check inside single-file shares)
• v1.15.0 (2024-09-08) changed upload deduplication to be default-disabled

🧪 new features

• #1212, #1214 range-select in the grid-view by click-and-drag (thx @icxes!) 3e3228e 72c5940

  • #1198, #1206 also works in the search-results view (thx @hackysphere!) 04f612f d32704e
• option to override the domain in certain links, so copyparty returns an external URL even if you're accessing it by a LAN address:
  • #1211 newly created shares 41d3bae
  • #255 newly uploaded files d925553
• new option vol-nospawn (volflag nospawn) to not automatically create the volume's folder on the server's HDD if it doesn't exist
• new option vol-or-crash (volflag assert_root) to intentionally crash on startup if a volume's folder doesn't already exist on the server HDD
• new option --flo to tweak the log-format used by the -lo option for logging to a file 826e84c
• #1197 u2c (commandline uploader): give up and crash if server is offline for longer than 3 minutes (configurable) 67c5d8d

🩹 bugfixes

• #1203 configured chmod/chown rules were not applied when a file was being deduped bef0772
• the unlistc* volflags could not be specified for single-file volumes 2664891
• the defensive renaming of uploaded readmes/logues would assume the default filenames, not considering the recently added option to customize these names c17c3be
• #1191 the ipu option can once again be used to reject connections from certain IP-ranges caf831f
  • this was a regression in v1.19.21 causing the server to crash on startup if such a config was attempted
• some empty folders could be created during startup in certain server-configs with nested volumes 4e67b46
• api: trying to ?ls nested virtual folders could return an error
• ui/ux:
  • #1179 improve errormessage if audio transcoding fails 7357d46
  • ensure a trailing slash when viewing a folder with the h permission; good for relative links in html-files

🔧 other changes

• #1193, #1194: NixOS improvements (thx @toast003!) 9d223d6 d5a8a34
• truncate huge errormessages from ffmpeg so the log doesn't get flooded 3aebfab
• ui/ux:
  • the dl button (to download selected files individually) now skips folders, since that never worked bc24604
  • #1200 add html classes to make custom styling easier c46cd7f
  • rephrase errormessages from see serverlog to see fileserver log
• docs:
  • mention in the readme that uploading files from a deeply nested folder using a webbrowser on Windows can fail because browsers don't handle the max-pathlen limitation of Windows optimally (not a copyparty-specific issue, but still hits us)

🌠 fun facts

• n/a; no fun has been had since v1.20.0
  • (that's a lie btw, sniffing the airwaves is pretty darn fun 😁)

💾 what to download?

• except for u2c.exe, all of the options above are mostly equivalent
• the zip and tar.gz files below are just source code
• python packages are available at PyPI
