Like we did for previous Godot 4.x versions (with #874, #1136, and #1267), this pinned issue will be used to list the godot-cpp commits which are in sync with matching Godot 4.3 beta and RC snapshots.

• 4.3-beta1: 45be6d0
• 4.3-beta2: c414c2b (should also work with 4.3-beta3 and 4.3-rc1)
• 4.3-rc2: daf6ad3
• 4.3-rc3: 11773e5

To benefit from non-compat breaking changes to godot-cpp on an older snapshot, you might be able to get it to work by using godot-cpp master and syncing the contents of gdextension manually with the official snapshot you're using (i.e. dumping the extension API and GDExtension interface with godot --dump-extension-api --dump-gdextension-interface).
