Release 15.4.9

[camscale]

• Honor proxy templates in tsh ssh. #44027
• Fixed Redshift auto-user deactivation/deletion failure that occurs when a user is created or deleted and another user is deactivated concurrently. #43975
• Teleport AMIs now optionally source environment variables from /etc/default/teleport as regular Teleport package installations do. #43961
• Enabled setting event types to forward, skip events, skip session types in event-handler helm chart. #43939
• Correctly propagate extraLabels configured in teleport-kube-agent chart values to post-delete hooks. A new extraLabels.job object has been added for labels which should only apply to the post-delete job. #43931

• Fixed session recordings getting overwritten or not uploaded. #42164

Enterprise:
