A red ✕ next to the filter selector appears whenever the filter is not
"All" and resets it to "All" in one click (pysimFsFilterClear).  Bump
VERSION/pyproject/PWA header to 3.40.2 and the SW cache to simple-v487.

 ## [Unreleased]
 
+## [3.40.2] — 2026-10-26
+
+### Added
+
+- **File filter: reset (✕) button.**  A red ✕ to the right of the filter
+  selector appears whenever the filter is not "All" and resets it to "All"
+  in one click.
+
+## [3.40.1] — 2026-10-26
+
+### Changed
+
+- **File filter: drop the "SMS-related" / "CB-related" categories.**  Those
+  files are service-declared and already reachable through their per-service
+  filter options, which carry the per-spec service names ("Short Message
+  Storage (SMS)", "SMS Parameters (SMSP)", "Short Message Status Reports
+  (SMSR)", "Cell Broadcast Message Identifier (CBMI)", "Cell Broadcast
+  Message Identifier Ranges (CBMIR)").
