   - Add `python_basedpyright` as an alternative Python language server
   - Nix/nixd: support custom `ls_path` launchers and external JSON settings through `config_path` #1737
+  - Fix: `get_diagnostics_for_file` crashed with `SolidLSPException` for any Ansible file with at least
+    one lint finding, because `ansible-language-server` doesn't implement `textDocument/documentSymbol`
+    and the request used to map diagnostics onto owning symbols just threw. `AnsibleLanguageServer` now
+    overrides that request to return `None` directly, so diagnostics fall back to being grouped under
+    the file-level path as already documented #1758
 
 * JetBrains:
   - `jet_brains_find_symbol`: Disallow wildcard-only search, delegating to overview tool if request is for file
