Full changelog

Description

  • Fixed an issue where generated installer scripts could incorrectly escape special characters in some values. #67192
  • Fixed a bug in Teleport Connect where the last terminal input could be logged to renderer.log if the terminal closed on its own — for example, when a tsh ssh session is dropped by the remote side (idle timeout, network disconnection) after the user pasted content but before they pressed Enter. #67173
  • Fixes an issue preventing joins using the azure join method in regions where the trust chain has been updated with an additional intermediate. #67140
  • Fix device trust for remote users connecting to a trusted cluster. #67032
  • Fixed a TLS certificate error that prevented users from connecting to Amazon Keyspaces databases through Teleport. #66975
  • Fixed an issue where Windows desktop LDAP discovery could conflict with dynamic registration causing desktops to be removed from the cluster. #66802
  • Improved the error message on login in tsh and Teleport Connect when /webapi/ping returns a non-200 response. #66713
  • Raise the app access upstream response-header cap from 5 minutes to 1 hour so long-running HTTP requests complete. #66686
  • Updated Go to 1.25.10. #66570
  • Improved the performance of VNet on macOS by eliminating unnecessary reconnects. #66561
  • Reduced unnecessary S3 uploads for Athena audit log deployments that publish directly to SQS by applying the correct SQS message size limit when the client has sqs:GetQueueAttributes permission, instead of always using the 256 KB SNS limit. #66533
  • Improved Teleport Connect startup reliability on Windows. #66510
  • Hardened event handler so it recovers in case of malformed session ID or corrupted data directory. #66472
  • Fixed app access dropping URL fragments through the auth redirect flow. #66461
  • Fixed an issue preventing host sudoers entries from being written on newer Linux distributions (i.e. Ubuntu 25.10) using sudo-rs. #66434
  • Fixed an issue that could cause LDAP discovery to fail when a single desktop service discovers large numbers of hosts. #66400
  • Fixed a rare input swallowing bug when resuming a moderated Node session. #66369
  • Fixed possible unavailability of Proxy service instances as a result of some API errors. #66313

Enterprise:

  • Enterprise licenses with a devices limit for device trust can now enroll unlimited devices.
  • Fixed a bug that could cause panics in Teleport's SAML IdP during failure scenarios.
