 Are you sure you're actually building with tree-sitter enabled? Ensure 
 you're passing `--with-tree-sitter` to `configure`.
 
 The changes made in tree-sitter 0.26 had to be explicitly accounted for 
 in upstream Emacs for the upcoming Emacs 31, and the commit which 
 accounted for these changes was never backported to Emacs 30:
 
 https://github.com/emacs-mirror/emacs/commit/d587ce8c65a0e22ab0a63ef2873a3dfcfbeba166
 
 You can see the exact details of what needed accounting for in the 
 commit above. I can assure you that attempting to build Emacs 30 with 
 tree-sitter support enabled with tree-sitter 0.26 fails due to the 
 `ts_language_version` function no longer existing in 0.26 as mentioned 
 above.
 
 Downgrading to 0.25 makes the problem go away, as the function is no 
 longer missing.
