Full Changelog: v8.10.0.0...v8.10.1.0

v8.10.0.0

New version of the application API

In this release, we are introducing a new version of the Application API v9 (preview). It is an interface designed for internal communication between the application and the remote server. The new version brings improvements in performance, security, and overall ecosystem stability. It offers an optimized request architecture, shorter response times, and more efficient resource management. The updated authorization mechanism also ensures a higher level of data protection.

Important information for Stella Plus subscribers

API v9 is not compatible with version v8. Due to the updated authorization mechanism, subscribers will need to reclaim their benefits on the patrons.sefinek.net website.

Important information regarding ReShade

This update allows quick switching between the standard version of ReShade and the version with full add-on and depth buffer support. The default setting is the standard version. For Stella Plus subscribers, the full add-on support version will be enabled automatically after launching 'Stella Plus App.exe'.
