Full Changelog: v2024.11...v2024.11.1-draft

v2024.11

This release brings SPIRV specialization constants, where clause, type equality constraints,
and tightened up Slang's language support for interface extensions, along with serveral
SPIRV and language server fixes.

The compilation API and slangc now supports identifying entrypoints defined in namespaces or structs.

Breaking Changes

Extensions on interface types are no longer allowed:

interface IFoo { ... }
extension IFoo
{}

The original extension IFoo syntax is replaced by more proper generic syntax:

extension<T:IFoo> T
{}
