# 5.99. Release Notes for Buildbot 0.9.0b6

The following are the release notes for Buildbot 0.9.0b6 This version was released on January 20, 2016.

See Upgrading to Buildbot 0.9.0 for a guide to upgrading from 0.8.x to 0.9.x

## 5.99.1. Master

### 5.99.1.1. Features

- Builders ui page has improved tag filtering capabilities

- Home page enhanced with the list of recent builds sorted by builder

- `IRC` reporter has been partially ported to work on data api.

### 5.99.1.2. Fixes

- better stability and reliability in the UI thanks to switch to buildbot data-module

- fix irc

### 5.99.1.3. Changes for Developers

- properties object is now directly present in build, and not in build_status. This should not change much unless you try to access your properties via step.build.build_status. Remember that with PropertiesMixin, you can access properties via getProperties on the steps, and on the builds objects.

- Javascript Data Module is now integrated, which sets a definitive API for accessing buildbot data in angularJS UI.

## 5.99.2. Slave

### 5.99.2.1. Features

- The `DockerLatentBuildSlave` image attribute is now renderable (can take properties in account).

- The `DockerLatentBuildSlave` sets environment variables describing how to connect to the master. Example dockerfiles can be found in https://github.com/buildbot/buildbot-contrib/tree/master/master/contrib/docker.
