 ## Features
-- Expose github.actor_id, github.workflow_ref & github.workflow_sha as environment variable (#2249)
-- Added worker and listener logs to stdout (#2291, #2307)
+- Displays the error logs in dedicated sub-sections of the Initialize containers section (#2182)
+- Add generateServiceConfig option for configure command (#2226)
+- Setting debug using GitHub Action variables (#2234)
+- run.sh installs SIGINT and SIGTERM traps to gracefully stop runner (#2233, #2240)
+
 
 ## Bugs
-- Made github.action_status output lowercase to be consistent with job.status' output (#1944)
+- Use Global.Variables instead of JobContext and include action path/ref in the message. (#2214)
 
 ## Misc
-- Added small size runner image for ARC (#2250)
-- Small change to Node.js 12 deprecation message (#2262)
-- Added the option to use the --replace argument to the create-latest-svc.sh (#2273)
-- Made runner_name optional defaulting to hostname in delete.sh script (#1871)
-- Return exit code when MANUALLY_TRAP_SIG is exported (#2285)
-- Use results for uploading step summaries (#2301) with limited size (#2321)
+- Allow '--disableupdate' in create-latest-svc.sh (#2201)
+- Fix markup for support link (#2114)
+- Add runner devcontainer (#2187)
+- Setup linter for Runner (#2211, #2213, #2216)
 
 ## Windows x64
 We recommend configuring the runner in a root folder of the Windows drive (e.g. "C:\actions-runner"). This will help avoid issues related to service identity folder permissions and long file path restrictions on Windows.
