 ## Features
 
-- Add Runner Configuration option to disable auto update `--disableupdate` (#1558)
-- Introduce `GITHUB_ACTIONS_RUNNER_TLS_NO_VERIFY` env variable to skip SSL Cert Verification on the Runner (#1616)
-- Adds support for downloading trimmed versions of the runner when the entire package does not need to be upgraded (#1568)
+- Make run.sh|cmd handle update without quitting so containers using them as entrypoints don't exit on update (#1646, #1633, #1708)
+- Add support for Step Summary (#1642, #1667, #1712) 
+- Pass jobId to the actionsDownloadInfo controller (#1639)
+- updated systemd svc.sh to accept custom service file (#1612) 
+- Add ability to specify runner group when creating service (#1675)
+- Prefer node16 over node12 when running internal scripts (#1621) 
+- Sending telemetry about actions usage. (#1688) 
+- Bump node12 version to latest (#1651)
+- Add internal to node version function and use better env var name (#1715)
+- Force JS Actions Node version to 16 if FF is on unless user opted out (#1716)
 
 ## Bugs
-- Set Outcome/Conclusion for composite action steps (#1600)
+- Fix windows console runner update crash (#1670) 
+- Retry policy for methods GetTenantCredential and GetJITRunnerTokenAsync (#1691)
+- Skip DeleteAgentSession when the acess token has been revoked. (#1692)
+- Repaired hashFiles call so if error was thrown, it was returned to process invoker (#1678)
+- Runner throws null ref exception when new line after EOF is missing (#1687)
+- Lets allow up to 150 characters for services on linux/mac (#1710) 
 
 ## Misc
 
-- Update `run.sh` to more gracefully handle updates (#1494)
-- Use 8Mb default chunking for File Container Uploads (#1626)
-- Performance improvements in handling large amounts of live logs (#1592)
-- Allow `./svc.sh stop` to exit as soon as runner process exits (#1580)
-- Add additional tracing to help troubleshoot job message corruption (#1587)
-
+- Added examples and aligned language within docs/checks/actions.md (#1664)
+- Problem with debugging on macOS M1 (#1625) 
+- Fix typo in hashFiles.ts. (#1672) 
+- Allow mocked updates for E2E testing (#1654)
+- Move JobTelemetry and StepsTelemetry into GlobalContext. (#1680) 
+- Fix inconsistency of outputs (both canceled and cancelled are used (#1624)
 
 ## 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.
