 # Changelog
 
+## 2025-10-10 - 2.4.1 - fix(runtime/deno)
+Enable Deno runtime tests by adding required permissions and local settings
+
+- ts/tstest.classes.runtime.deno.ts: expanded default Deno permissions to include --allow-net, --allow-write and --sloppy-imports to allow network access, file writes and permissive JS/TS imports
+- ts/tstest.classes.runtime.deno.ts: updated fallback permissions used when building the Deno command to match the new default set
+- Added .claude/settings.local.json with a set of allowed local commands/permissions used for local development/CI tooling
+
 ## 2025-10-10 - 2.4.0 - feat(runtime)
 Add runtime adapters, filename runtime parser and migration tool; integrate runtime selection into TsTest and add tests
