Hello Sharks! 🦈

We are releasing another version for stable release after a month since the last one (1.82.14).
This version focused on Bug Fixes, especially with IO_SharingViolationException errors, other bunch of minor performance improvements on Video background playback with Acrylic Effects enabled and reducing UI hangs while navigating between games/regions.

Servicing/Maintenance Mode Phase

Version 1.82.17 will mark as the 1.82.xxx releases enters "Servicing/Maintenance Mode", meaning that 1.82.xxx releases will no longer get any improvements or new features, unless any urgent changes or bug fixes that need to be pushed or backported.

We are going to plan other new features, improvements and changes to be pushed in later release, 1.83.xxx.
Hit us on our Official Discord or Create an Issue if you have ideas what features or changes you want to have in later 1.83.xxx or future release.

More information regarding the changes can also be found in the changelog below👇

What's new ? - 1.82.17

  • Sentry 5.0.1 -> 5.1.0
• [New] Prevent user to close launcher when critical operation is in progress, by @bagusnl

  • Read more

What's new? - 1.82.16

• [Fix] Errors when updating game that uses HDiff, by @neon-nyan
• [Imp] Update dependencies, by @neon-nyan
• [Imp] Reduce CPU overhead by swapping SoftwareBitmap to CanvasDevice and CanvasBitmap to draw video frames while "Acrylic Effect" mode enabled, by @neon-nyan
  • This reduces CPU overhead by removing routines to copy the video frames from software-based SoftwareBitmap, and instead use Direct3D-based CanvasBitmap as the frame source.
  • However, this improvement still runs single-threaded due to the copy routine still being done on the same thread as the UI thread.
• [Imp] Execute metadata config download and loading in parallel, by @neon-nyan
  • Instead of running the metadata download/update/load routine sequentially, the process will now be running in parallel at the same time. Making the metadata loading runs faster.
• [Imp] Reduce UI hangs while switching between regions, by @neon-nyan
• [Fix] Crash when clicking any Community Tools buttons, by @neon-nyan
• [Fix] Regression where some Game Settings might not refresh the page when Registry changes occurred outside of the launcher, by @neon-nyan

• [Imp] Use Persistent folder for Audio VO when possible, by @neon-nyan
• [Fix] Lock .NET SDK version to 9.0.1, by @bagusnl
• [New] Check for UAC availability status, by @shatyuka
  • UAC is needed for the game, when it's disabled it might give "Anti-cheat error" message and refusing to run the game. In this case, we might not recommend you to use debloated Windows Scripts/ISOs to avoid any compatibility issues.
• [Imp] CodeQA based on Qodana and ReSharper suggestions, by @neon-nyan
• [New] Introducing Hash extension for hashing FileStream, string, Span<T> and FileInfo with both synchronous and asynchronous version of the methods. The methods uses generic type of any member of HashAlgorithm (Such as: MD5, SHA#, HMACSHA#, etc.) and NonCryptographicHashAlgorithm (Such as: Crc32, XxHash#, etc.) to specify which kind of hash to be used, by @neon-nyan
• [Imp] Separating InternalAppJSONContext members into its own JsonContext, by @neon-nyan
• [Imp] Update H.NotifyIcon to work with CsWin32 v0.3.162, by @neon-nyan

  • Update libwebp libraries to: https://github.com/webmproject/libwebp/tree/f8f241071001e1a3807f34a26a03a742ea843458

Note

Due to amount of changes being made into our codebases, we only push 1.82.16 update to preview release.
The changes for later stable release will be shipped in the next update (1.82.16) as well as preview.
Another thing to mention is that due to some bug fixes and performance related improvements in 1.82.16, we are moving the schedule for the next update of stable release (1.82.17) to at least, in the next week. If you feel this build is buggy for you, let us know and fallback to stable until further notice. We are sorry for the inconvenience.
