 # Changelog
 
+## 2026-04-30 - 2.10.1 - fix(mod_custom)
+make base64ts bundle output deterministic and clean up generated temp sourcemaps
+
+- Use a stable temporary bundle filename instead of a timestamp-based name so repeated base64ts builds produce identical output.
+- Delete the generated temporary sourcemap alongside the temp bundle to avoid leftover build artifacts.
+- Add a test covering deterministic base64ts output generation.
+- Update package scripts to use pnpm for tests and remove the allowimplicitany build flag.
+
 ## 2026-03-24 - 2.10.0 - feat(config)
 migrate project configuration to smartconfig.json and update bundler dependencies
