+Subject: [PATCH] Support Tree-sitter version 0.26 and later
+
+* src/treesit.c (init_treesit_functions)
+[TREE_SITTER_LANGUAGE_VERSION >= 15]: Define prototype for, and
+load 'ts_language_abi_version' instead of the deprecated (and
+removed in tree-sitter 0.26) 'ts_language_version'.
+(ts_language_abi_version) [TREE_SITTER_LANGUAGE_VERSION >= 15]:
+Define on WINDOWSNT, instead of 'ts_language_version'.
+(treesit_language_abi_version): New compatibility function.
+(treesit_load_language, Ftreesit_language_abi_version): Use
+'treesit_language_abi_version' instead of 'ts_language_version'.
