+## [0.1.2] - 2026-04-12
+
+### Fixed
+
+- `BufWritePre` formatters (e.g. conform.nvim format-on-save) now run on
+  autosave. The trigger autocmd now uses `nested = true`, so the `:write`
+  invoked from inside the `InsertLeave` / `TextChanged` / `FocusLost`
+  handler fires nested autocmds (see `:help autocmd-nested`).
+
+### Changed
+
+- Skip saves for unmodified, unnamed, or special (`buftype`) buffers instead
+  of always attempting a write.
+- Drop `:wall` — autosave only writes the buffer the event fired on.
+- Use `silent` (not `silent!`) so write errors surface instead of being
+  swallowed.
