- Fixed a crash in C++20 mode in Clang and Clangd when compile source
with compilation errors.
`Issue 53628 <https://github.com/llvm/llvm-project/issues/53628>`_
+- The template arguments of a variable template being accessed as a
+ member will now be represented in the AST.
Improvements to Clang's diagnostics
