1.84.1 Preview [Codename: Columbina] Pre-release
Pre-release

Hewwo, it's neon-nyan here~

It's beeeeeen a while since the last 1.83.x update. For now, this release is focusing on more quality improvements, bug fixes and internal code reworks rather than new features as we are preparing on reworking Collapse for new codebase.

That being said, this 1.84 update will be the marked as the last V1 release after roughly 4 years since the start of this project as we are going to move into V2 codebase starting this year (at Q3 or Q4 2026). Thank you so much for your continous support and interest in this project💖

Welcome to 1.84.x Release (Codename: Columbina)

UpdateIsAvailable-Campaign-Columbina
And so without further ado, let's dig into what's new in this release so far.

Preview 1.84.1 (Codename: Columbina) - What's new?

Reworked Background System

Since months, HoYoverse has updated HoYoPlay to support multiple background to display, including static image and dynamic background ones. This has been our backlog since this release as due to "spaghetti-code" nature of our entire codebase, this made us harder to adapt the changes and thus making Collapse still only support one static background image.

Thanks to this massive rework, we are now able to pull-off this feature by splitting the parts of the code into its own element, making it more easier and more manageable for the change and for incoming improvements.

We are also moving to FFmpeg as our secondary library for background video decoder if no built-in codec is present. You will be prompted to install the FFmpeg library if none of the required built-in Windows Media Foundation codec for VP9 or any codec is present.

FFmpeg is licensed and distributed under GNU Lesser General Public License, version 2.1 (LGPLv2.1)

2026-04-11.16-22-41.webm

The experience might still be sluggish due to rushed implementation. But this will be improved in future updates🤞

Update: 2026/03/27

Due to corrupted video background situation in any regions for Zenless Zone Zero game, FFmpeg has been set as a default decoder for Collapse Launcher now (You can opt-in for using built-in Windows Media Foundation decoder, though). You might be asked to install a new one if you don't have any defined in your system's Environment Variable.

2026-03-27.11-55-13.webm

Reworked Localization System #861

This is more like development-experience improvement rather than user focused ones. Previously in order to implement the localization for new elements, we have to manually map each class properties to represented JSON entries. Thanks to newly source-generated class mapper, every JSON entries will be mapped automatically. Each class properties can now be bind into UI element directly, making the UI able to update the visual itself rather than being told manually, one-by-one (which is expensive).

Reworked Download Speed Limiter #859

The feature has been long broken since last 1.83.x release due to inconsistency and changes to other download-related libraries. Even though if you're enabling this feature, you might experience that the download speed "isn't actually being limited" and noticing that your bandwidth is still being fully utilized. This feature should now be fully fixed by decentralizing the code of the feature into its own library and making it easier to maintain.

This feature could also be applied for any game plugins whose have v1-update4 API standard fully implemented.

Minor UI Adjustments

Not so noticeable UI changes at all. But it's worth to mention here.

1. News Carousel Design

1.83.13 Stable [Codename: Luna]

UpdateIsAvailable-Campaign

We've recently released a new launcher status tracker! Head on over to https://status.collapselauncher.com to see it!

Guess who's back, back again? Guess who's back, guess who's back? That's right! It's the Dev Team with a new mainline Stable release!

This release brings Stable in line with the new features present in Preview. This includes, but is not limited to: plugin subsystem, .NET 10 migration, Miliastra Wonderland support and a lot of bug fixing!

New: Plugin Subsystem

This is by far the most ambitious and difficult feature we've worked on. Through this, you may now launch additional games through Collapse, taking advantage of all its features and fluidity!

Please keep in mind that in order for this feature to work, you need to install the corresponding plugin. Plugins are managed through the App Settings page, by clicking on the "Open Plugin Management Menu" button. A list of plugins can be found on our website.

The plugins update process follows a similar procedure to metadata updates, though you can choose not to update the plugin if you want. No support will be given if you are on an outdated version of a plugin.

Plugins are created by 3rd-party developers and are not subject to Collapse policies. Because of this, we can't actively provide support to users that use plugins that are not developed by Collapse developers. Here's a list of currently-available plugins:

We ask that, should you have any issues, you open a ticket on the respective repositories. The owner will be able to assist you further. Plugins made by the core development team are supported on the latest version only.

New: Support for updating Miliastra Wonderland package

Just like HoYoPlay, Collapse can now update the Miliastra Wonderland package for Genshin Impact. There's a new icon for it too!

Update: Switch to .NET10 for Collapse builds

Collapse now runs on .NET10! Because of that, we are able to bring numerous performance improvements to our builds, which run on NativeAOT. You can check out most changes brought through .NET10 here.

Major changes

Because of the amount of commits (over 800), the changes won't be listed. Instead, we encourage you to look at the full release changelog down below.

Various Localization Updates

As always, we want to thank are awesome community for providing an amazing localization for our project. Collapse is now localizable in 18 languages and dialects! <3

Minor changes

Because of the amount of commits (over 800), the changes won't be listed. Instead, we encourage you to look at the full release changelog down below.
