 ## Bugs
-- Fix windows console runner update crash (#1670) 
+- Fixed an issue where websockets failed to successfully close when posting log lines (#1790)
-- 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-- Skip DeleteAgentSession when the acess token has been revoked.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
-
-- 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.
