Release v2.20250913.0

Wrap-up

This release primarily marks Invidious companion's ascend out of beta and its stable integration thereof into Invidious!

For those unaware Invidious companion is the successor to the inv-sig-helper tool, designed to securely pass YouTube's attestation checks and allow for the efficient retrieval and playback of video streams reliably.

Companion delivers YouTube fixes faster since it’s built on the community-driven YouTube.js project, used by many open source projects such as FreeTube.

For more information see https://github.com/iv-org/invidious-companion and https://docs.invidious.io/installation/

But companion isn't the only new thing in this release!

Invidious will no longer error out completely as soon as a single item failed to parse in search results, channel pages, etc. Instead it now handles it gracefully by substituting those problematic items with an error card and rendering the page normally.

The player has gained some quality of life features such as being able to choose a default playlist for videos to be added to, or persisting caption appearance settings across the session.

Base Invidious video retrieval without Invidious companion has also been made more stable.

And finally a significant amount of bugs were fixed alongside many other minor improvements.

New features & important changes

For Users

• DASH is now enabled by default due to YouTube's removal of the 720p non-dash streams
• Javascript licencing info has been added to all of Invidious' scripts, restoring full compatibility with LibreJS
• There is no longer an option for a text captcha during registration due to the shutdown (presumably) of the upstream service
• Parse errors in feeds will no longer render the entire feed unusable and instead will substitute only the broken items with error cards
• Keyboard shortcuts have been added to configure caption styles:
  • -,= can be used to change the font size
  • o can be used to cycle the opacity of the caption text
  • w can be used to cycle the opacity of the caption box
• Caption styles changed through the VideoJS menu will now persist
• You can now choose a default playlist to add videos to instead of needing to manually select one each time

For instance owners

• Invidious companion support has been added to replace the deprecated inv-sig-helper
• DASH is now the default resolution! Please ensure that your instances can withstand the significantly higher bandwidth usage or manually configure your instance to use non-dash streams by default
• Invidious will now warn when it is unable to connect to the database instead of failing silently
• The text captcha during registration has been removed due to the shutdown (presumably) of the upstream service

For developers

• Dependabot has been added to keep Github Actions and Docker dependencies up-to-date.

• CI version matrix has been bumped to the latest patch release for each minor version

• The versions of Crystal that we test in CI/CD are now: 1.12.2, 1.13.3, 1.14.1, 1.15.1, 1.16.3

• Kilt is no longer a dependency of Invidious

• The ARM64 docker image builds (and the test CI) has been changed to use Github's ARM64 runner instead of QEMU

• An "error" JSON object can now be returned in various API responses in-place of an item that has failed to parse:

    {
      "type": "parse-error",
      "errorMessage": "...",
      "errorBacktrace": "..."
    }

Bugs fixed

Wrap-up

This release brings the long awaited feature of supporting multiple audio tracks in a video, some bug fixes and UX improvements, and many other things primarily oriented to self-hosting instances, and developers using the API.

The Community channel tab has been replaced by Posts in light of YouTube changes, but the URL remains the same.

Tamil is now available as an interface language

Release v2.20241110.0

Wrap-up

This release is most importantly here to fix to the annoying "Youtube API returned error 400"
error that prevented all channel pages from loading.

If you're updating from the previous release, it provides no improvements on the ability to play
videos. If updating from a commit in-between release, it removes the "Please sign in" error caused
by a previous attempt at restoring video playback on large instances.

In the preferences, a new option allows for control of video preload. When enabled, this option
tells the browser to load the video as soon as the page is loaded (this used to be the default).
When disabled, the video starts loading only when the "play" button is pressed.

New interface languages available: Bulgarian, Welsh and Lombard

New dependency required: tzdata.

An HTTP proxy can be configured directly in Invidious, if needed.
NOTE: In that case, it is recommended to comment out force_resolve.

New features & important changes

For users

• Channels: Fix "Youtube API returned error 400" error preventing channel pages from loading
• Channels: Shorts can now be sorted by "newest", "oldest" and "popular"
• Preferences: Addition of the new "preload" option

• Added "Filipino (auto-generated)" to the list of caption languages available
• Lots of new translations from Weblate

For instance owners

• Allow the configuration of an HTTP proxy to talk to Youtube
• Invidious tries to reconnect to inv_sig_helper if the socket is closed
• The instance list is downloaded in the background to improve redirection speed
• New colorize_logs option makes each log level a different color

For developpers

• /api/v1/channels/{id}/shorts now supports the sort-by parameter with the following values:
  newest, oldest and popular
• Older /api/v1/channels/xyz/{id} (tab name before UCID) were removed
• API/Search: New video metadata available: isNew, is4k, is8k, isVr180, isVr360,
  is3d and hasCaptions

Bugs fixed

User-side

New features & important changes

For users

• The search bar now has a button that you can click!
• Youtube URLs can be pasted directly in the search bar. Prepend search query with a
  backslash (\) to disable that feature (useful if you need to search for a video whose
  title contains some youtube URL).
• On the channel page the "streams" tab can be sorted by either: "newest", "oldest" or "popular"
• Lots of translations have been updated (thanks to our contributors on Weblate!)
• Videos embedded in local HTML files (e.g: a webpage saved from a blog) can now be played

For instance owners

• Invidious now has the ability to provide a po_token and visitordata to Youtube in order to
  circumvent current Youtube restrictions.
• Invidious can use an (optional) external signature server like inv_sig_helper. Please note that
  some videos can't be played without that signature server.
• The Helm charts were moved to a separate repo: https://github.com/iv-org/invidious-helm-chart
• We have changed how containers are released: the latest tag now tracks tagged releases, whereas
  the master tag tracks the most recent commits of the master branch ("nightly" builds).

For developpers

• The versions of Crystal that we test in CI/CD are now: 1.9.2, 1.10.1, 1.11.2, 1.12.1.
  Please note that due to a bug in the libxml bindings (See #4256), versions prior to 1.10.0
  are not recommended to use.
• Thanks to @syeopite, the code is now ameba compliant.
• Ameba is part of our CI/CD pipeline, and its rules will be enforced in future PRs.
• The transcript code has been rewritten to permit transcripts as a feature rather than being
  only a workaround for captions. Trancripts feature is coming soon!
• Various fixes regarding the logic interacting with Youtube
• The sort_by parameter can be used on the /api/v1/channels/{id}/streams endpoint. Accepted
  values are: "newest", "oldest" and "popular"

Bugs fixed

User-side

• Channels: fixed broken "subscribers" and "views" counters
• Watch page: playback position is reset at the end of a video, so that the next time this video
  is watched, it will start from the beginning rather than 15 seconds before the end
• Watch page: the items in the "add to playlist" drop down are now sorted alphabetically
• Videos: the "genre" URL is now always pointing to a valid webpage
• Playlists: Fixed Could not parse N episodes error on podcast playlists
• All external links should now have the rel attibute set to noreferrer noopener for
  increased privacy.
• Preferences: Fixed the admin-only "modified source code" input being ignored
• Watch/channel pages: use the full image URL in og:image and twitter:image meta tags

API

• fixed the local parameter not applying to formatStreams on /api/v1/videos/{id}
• fixed an Index out of bounds error hapenning when a playlist had no videos
• fixed duplicated query parameters in proxied video URLs
• Return actual video height/width/fps rather than hard coded values
• Fixed the /api/v1/popular endpoint not returning a proper error code/message when the
  popular page/endpoint are disabled.

tagging system was not used for a long time, we're starting back at 2 as the major version.
Zero being the previous tagged releases, and One being the "rolling release era".

Hotfix 0.20.1

! IMPORTANT !

Releases are deprecated, build directly from master
