• Update path sanitizer it allow @. #1985

2.6.0

This release of Teleport brings new features, significant performance and usability improvements as well usual bugfixes.

During this release cycle, the Teleport source code has been audited for security vulnerabilities by Cure53 and this release (2.6.0) contains patches for the discovered problems.

New Features

• Support for DynamoDB for storing the audit log events. #1755
• Support for Amazon S3 for storing the recorded SSH sessions. #1755
• Support for rotating certificate authorities (CA rotation). [#1899] (gravitational#1899)
• Integration with Linux PAM (pluggable authentication modules) subsystem. #742 and #1766
• The new CLI command tsh status shows users which Teleport clusters they are authenticated with. #1628

Additionally, Teleport 2.6.0 has been submitted to the AWS marketplace. Soon AWS users will be able to create properly configured, secure and highly available Teleport clusters with ease.

Configuration Changes

• Role templates (depreciated in Teleport 2.3) were fully removed. We recommend migrating to role variables which are documented here

• Resource names (like roles, connectors, trusted clusters) can no longer contain unicode or other special characters. Update the names of all user created resources to only include characters, hyphens, and dots.

• advertise_ip has been deprecated and replaced with public_addr setting. See #1803 The existing configuration files will still work, but we advise Teleport administrators to update it to reflect the new format.

• Teleport no longer uses boltdb back-end for storing cluster state by default. The new default is called dir and it uses simple JSON files stored in /var/lib/teleport/backend. This change applies to brand new Teleport installations, the existing clusters will continue to use boltdb.

• The default set of enabled cryptographic primitives has been updated to reflect the latest state of SSH and TLS security. #1856.

Bug Fixes

The list of most visible bug fixes in this release:

• tsh now properly handles Ctrl+C #1882
• High CPU utilization on ARM platforms during daemon start-up. #1886
• Terminal window size can get out of sync on AWS. #1874
• Some CLI commands print errors twice. #1889
• SSH session playback can be interrupted for long sessions. #1774

Bug Fixes

• Binaries for macOS have been rebuilt to resolve "certificate signed by a unknown authority" issue.

2.5.0

This is a major release of Teleport. Its goal is to make cloud-native deployments easier. Numerous AWS users have contributed feedback to this release, which includes:

New Features

• Auth servers in highly available (HA) configuration can share the same /var/lib/teleport data directory when it's hosted on NFS (or AWS EFS). #1351

• There is now an AWS reference deployment in examples/aws directory. It uses Terraform and demonstrates how to deploy large Teleport clusters on AWS using best practices like auto-scaling groups, security groups, secrets management, load balancers, etc.

• The Teleport daemon now implements built-in connection draining which allows zero-downtime upgrades. See documentation.

• Dynamic join tokens for new nodes can now be explicitly set via tctl node add --token. This allows Teleport admins to use an external mechanism for generating cluster invitation tokens. #1615

• Teleport now correctly manages certificates for accessing proxies behind a load balancer with the same domain name. The new configuration parameter public_addr must be used for this. #1174.

Improvements

• Switching to a new TLS-based auth server API improves performance of large clusters. #1528

• Session recordings are now compressed by default using gzip. This reduces storage requirements by up to 80% in our real-world tests. #1579

• More user-friendly authentication errors in Teleport audit log helps Teleport admins troubleshoot configuration errors when integrating with SAML/OIDC providers. #1554, #1553, #1599

• tsh client will now report if a server's API is no longer compatible.

Bug Fixes

• tsh logout will now correctly log out from all active Teleport sessions. This is useful for users who're connected to multiple Teleport clusters at the same time. #1541

• When parsing YAML, Teleport now supports -- list item separator to create multiple resources with a single tctl create command. #1663

• Fixed a panic in the Web UI backend #1558

Behavior Changes

Certain components of Teleport behave differently in version 2.5. It is important to note that these changes are not breaking Teleport functionality. They improve Teleport behavior on large clusters deployed on highly dynamic cloud environments such as AWS. This includes:

• Session list in the Web UI is now limited to 1,000 sessions.
• The audit log and recorded session storage has been moved from /var/lib/teleport/log to /var/lib/teleport/log/<auth-server-id>. This is related to #1351 described above.
• When connecting a trusted cluster users can no longer pick an arbitrary name for them. Their own (local) names will be used, i.e. the cluster_name setting now defines how the cluster is seen from the outside. #1543

2.4.7

This release of Teleport contains a bugfix.

Bug Fixes

• Only reset SIGINT handler if it has not been set to ignore. #1814
