## oh-so-fast
|
|
starting from this update, cobalt can run several instances in parallel, reducing load on individual instances and making it much faster.
|
|
previously cobalt ran on *only one thread*, and it's honestly impressive that it lasted this long.
|
|
|
|
we tested cobalt under peak traffic load & same network conditions:
|
|
- initial request processing is now **~14 times faster than before**.
|
|
- starting a tunnel is now **~32 times faster**.
|
|
|
|
<div style="display: flex; justify-content: center;">
|
|
|
|
| | 10.2 | **10.3** |
|
|
|-------------------|---------|------------|
|
|
| processing | 14780ms | **1070ms** |
|
|
| starting a tunnel | 11660ms | **360ms** |
|
|
|
|
</div>
|
|
|
|
these tests weren't really scientific as we based them on screen recordings,
|
|
but the point still stands: cobalt no longer slows down and runs as fast as it can.
|
|
|
|
## youtube improvements
|
|
- added a [new hls option](/settings/video#youtube-hls) that allows for downloading *more formats* of youtube videos.
|
|
- fixed an issue that caused long youtube videos to get abruptly cut off. if you still experience this issue, try enabling the [new hls option](/settings/video#youtube-hls) in settings!
|
|
- added an option to [pick any audio track language](/settings/audio#youtube-dub) for youtube videos in settings. all languages that youtube supports are listed, cobalt will fall back to default if preferred language isn't available.
|
|
- if a [youtube codec](/settings/video#youtube-codec) isn't available, cobalt will now fall back to the next best one.
|
|
|
|
## meet weblate, a place where you can translate cobalt
|
|
we're finally ready to invite you to translate cobalt to any language you like! your translation contributions are linked to your github account, so you'll show up in cobalt's contributors list.
|
|
|
|
you can start translating cobalt at [i18n.imput.net](https://i18n.imput.net/) right now!
|
|
|
|
thank you for showing such an overwhelming amount of interest in making cobalt more accessible around the world, we really appreciate it!

|

|
|
|
|
## documentation improvements
|
|
- all [documentation on github](https://github.com/imputnet/cobalt) was majorly improved. all projects and docs are now listed in the main readme. all docs are now easier to read and follow.
|
|
- added a new document outlining all [instance protection methods](https://github.com/imputnet/cobalt/blob/main/docs/protect-an-instance.md) along with step-by-step tutorials on how to configure them.
|
|
- added a tutorial for [configuring a cobalt instance for youtube downloading](https://github.com/imputnet/cobalt/blob/main/docs/configure-for-youtube.md).
|
|
- updated [contribution guidelines](https://github.com/imputnet/cobalt/blob/main/CONTRIBUTING.md).
|
|
- updated [examples](https://github.com/imputnet/cobalt/tree/main/docs/examples) for cookie & docker compose files. we now recommend running cobalt api as **read only** image, as it ensures that it wasn't tampered with. we do it on our servers, too.
|
|
|
|
## internal improvements for nerds
|
|
- added support for api keys, api instance hosters are now able to limit access to a set of people. you can see [how to configure them on github](https://github.com/imputnet/cobalt/blob/main/docs/protect-an-instance.md#configure-api-keys).
|
|
- cobalt api docker image is now running alpine & node 23. it's also much smaller than before.
|
|
- instances now log whether they were able to load cookies or api keys. no more guessing if your config works or not.
|
|
- updated the console error when cobalt api is configured incorrectly.
|
|
- majorly refactored the youtube module.
|
|
- lots of general api code refactoring.
|
|
- improved settings schema migration on frontend.
|
|
- removed outdated api functions, util scripts, and docs.

## fixed a XSS vulnerability that wasn't exploited
|
|
a malicious cobalt instance could serve links with the javascript: protocol, resulting in XSS when the user tries to download an item from a picker.
|
|
|
|
as far as we know, this vulnerability was never found and exploited in the wild, but we still urge all frontend instance hosters to **update their instances asap**. cobalt.tools and all other instances that configured CSP correctly weren't affected by this vulnerability.
|
|
|
|
this issue was fully fixed in [c4be1d3](https://github.com/imputnet/cobalt/commit/c4be1d3a37b0deb6b6087ec7a815262ac942daf1) and [an advisory with CVE was posted on github](https://github.com/imputnet/cobalt/security/advisories/GHSA-cm4c-v4cm-3735).
|
|
|
|
if you ever discover a security vulnerability in cobalt, please report it responsibly [on github](https://github.com/imputnet/cobalt/security/advisories/new). we'll make sure to fix it as soon as possible!
|
|
|
|
## where's 10.2?
|
|
we were very excited to release the first part of changes, so we bumped the version early. then, we decided to make cobalt faster, so now we're at 10.3!
|
|
|
|
*we also silently released changes in prod before the announcement, teehee :3c*
|
|
|
|
## all changes are on github
|
|
as always, you can check [all commits since the 10.1 release on github](https://github.com/imputnet/cobalt/compare/f461b02...c021293) for even more details.
