August’s 2023.8 release brings to the IDE some important licensing fixes for both SSO and Legacy login users to stop issues with sessions not refreshing when expected; a fresh new look to the Templates screens on the Start Page; a change back to "Test" for the default target set when creating new projects (plus, a slight change to runtime names); the ability to open more asset types in external editors (and set in your Preferences if there is a specific editor you want to be used) and also to inspect Included Files; the ability to tell Feather to apply certain rules to specific files/groups; and a tweak to workspace tab-management so you can't accidentally drag a workspace tab out to be its own new window.
There is also a new tool for reporting GameMaker bugs to us inside the Help menu and have this a) somewhat automate the process for you, and b) report the issue to a new public-facing bug database using your GitHub account, so you can then get some progress on your issue later on. Please always check the current how-to information on reporting your bugs and the known issues on the bugs site before sending any reports!

The runtimes have received a large number of new functions for creating debug/design GUI elements and the ability to type in console commands to perform your functions or print values at runtime; support for checking arrays and using tilemaps in collision functions; a new Compressor audio effect and three new SDF font rendering effects; new functions for rotating and colouring particles and others which allow you to burst the particles previously created in the editor; IPv6 support on all platforms which support it; and many other new features and fixes.
Please do check your SDKs and other external tools are the correct versions before doing any builds, as a couple of platforms have been updated since 2023.6 - you can see our Required SDKs FAQ and the various platform setup guides that page links to in order to get all of this information at any time.
