# Changelog

## 2.3 

This release focus was to increase Teleport user experience, including:

* Easier configuration
* Better documentation
* Improved CLI interface
* Make the Web UI better

#### Improvements

* Web UI: users can connect to OpenSSH servers using the Web UI.
* Web UI: arbitrary logins are supported, in addition to role-defined ones.
* CLI: trusted clusters can now be managed on the fly without having to edit Teleport configuration. [#1137](https://github.com/gravitational/teleport/issues/1137)
* CLI: `tsh login` supports exporting a user identity into a file to be used later with OpenSSH.
* `tsh agent` command has been deprecated: users are expected to use native SSH Agents on their platforms.

#### Teleport Enterprise 

* More granular RBAC rules [#1092](https://github.com/gravitational/teleport/issues/1092)
* Role definitions now support templates. [#1120](https://github.com/gravitational/teleport/issues/1120)
* Authentication: Teleport now supports multilpe OIDC/SAML endpoints.
* Configuration: local authentication is always enabled as a fallback if a SAML/OIDC endpoints go offline.
* Configuration: SAML/OIDC endpoints can be created on the fly using `tctl` and without having to edit configuration file or restart Teleport.
* Web UI: it is now easier to turn a trusted cluster on/off [#1199](https://github.com/gravitational/teleport/issues/1199).

## 2.0.6

### Bugfixes

* Fixed regression in TLP-01-009.

## 2.0.5

Teleport 2.0.5 contains a variety of security fixes. We strongly encourage anyone running Teleport 2.0.0 and above to upgrade to 2.0.5.

The most pressing issues (a phishing attack which can potentially be used to extract plaintext credentials and an attack where an already authenticated user can escalate privileges) can be resolved by upgrading the web proxy. However, however all nodes need to be upgraded to mitigate all vulnerabilities. 

### Bugfixes

* Patch for TLP-01-001 and TLP-01-003: Check redirect.
* Patch for TLP-01-004: Always check is namespace is valid.
* Patch for TLP-01-005: Check user principal when joining session.
* Patch for TLP-01-006 and TLP-01-007: Validate Session ID.
* Patch for TLP-01-008: Use a fake hash for password authentication if user does not exist.
* Patch for TLP-01-009: Command injection in scp.

## 2.0.4

### Bugfixes

* Roles created the the Web UI now have `node` resource. [#949](https://github.com/gravitational/teleport/pull/949)

## 2.0.3

### Bugfixes

* Execute commands using user's shell.  [#943](https://github.com/gravitational/teleport/pull/943)
* Allow users to read their own roles. [#941](https://github.com/gravitational/teleport/pull/941)
* Fix User CA import. [#919](https://github.com/gravitational/teleport/pull/919)
* Role template defaults. [#916](https://github.com/gravitational/teleport/pull/916)
* Skip UserInfo if not provided. [#915](https://github.com/gravitational/teleport/pull/915)

[#874](https://github.com/gravitational/teleport/pull/874), [#876](https://github.com/gravitational/teleport/pull/876), [#883](https://github.com/gravitational/teleport/pull/883), [#892](https://github.com/gravitational/teleport/pull/892), and [#906](https://github.com/gravitational/teleport/pull/906)
