### Bug Fixes

- #2250: @michaelshobbs Fix missing $ sign in default nginx template

## 0.6.0

The big-six-o. This release is largely comprised of new features that should allow for easier management of dokku. The highlights of this release are:

- The proxy plugin has been enhanced to allow users to map container ports to host ports. In the 0.5.0 release, we changed the semantics of how Dockerfile `EXPOSE` calls work to better follow Docker's lead, which ended up breaking how some applications were deployed to dokku. Please read our documentation surrounding [port management](http://dokku.viewdocs.io/dokku/proxy/) for more details.
- Zero-downtime deploys can be disabled on a per-app and per-process basis. This can be used to speed up deploys when there are non-web processes being deployed, or when a user wishes to completely avoid any such waiting period. Please see the [checks documentation](http://dokku.viewdocs.io/dokku/checks-examples/) for further information.

Thanks to all the contributors who helped with this release, and a special thanks to @michaelshobbs for ferrying the majority of our new functionality to it's current state!

- #2244: @basgys Add InfluxDB to plugins

## 0.5.8

This release is the last release in the `0.5.x` series, and as such is mainly a bugfix release. Users are highly encouraged to upgrade to this release *before* moving to the upcoming `0.6.x` release, as we will be removing deprecated features at that point.

We've also added a small section to the [dokku homepage](http://dokku.viewdocs.io/dokku/) that lists the current core team. Feel free to look at their beautiful faces and imagine yourself contributing to Dokku and joining our core team. There are [quite a few ways to contribute](https://github.com/dokku/dokku/blob/master/CONTRIBUTING.md) - even without code/documentation - so feel more than free to jump on the bandwagon!

Finally, we've started an [Official Dokku Blog](https://dokku.github.io/), where we will post about dokku internals, roadmaps, potential use-cases, etc. An rss feed is available [here](https://dokku.github.io/feed.xml).

## 0.4.14

Hah you got us. We have to ship another 0.4.x release to fix issues with
running commands via `dokku run`. For quite a few releases, we've been
ignoring the `--rm` flag, meaning containers were lying around if you were
using `dokku run` in cron. This release fixes it, and is important enough

## 0.4.10

This release is mostly a bugfix release, though we have a few important changes:

- `dokku plugin:update` can now be used to update a specific plugin. Previously, this could potentially result in an error a user would have to manually resolve.
- We have started labeling all dokku-managed containers. In a future minor release, triggering a `dokku cleanup` will remove *only* exited containers that are managed by dokku. This change allows users to start containers outside of dokku and be assured that dokku would not inadvertently remove them.

Thanks to all the contributors who helped with this release!

## 0.4.9

This release is significant for two reasons:

- A bugfix for git submodule support that was broken in 0.4.7
- Improved and tested support for modern variants of Ubuntu/Debian. This should also improve support for docker-based deployments of dokku, as well as potential support for the upcoming Ubuntu 16.04 release.

Thanks to all the contributors who helped with this release!

### Bug Fixes

- #1810: @josegonzalez Fix debian packaging for usage inside of docker containers

## 0.4.8

If upgrading to 0.4.8, please note that we have tightened the application naming schema, per docker requirements. Upgrade your dokku installation to 0.4.7 first to take advantage of the `dokku apps:rename` command if you are having issues with the new requirement.

### Bug Fixes

## 0.4.7

A few notable new features:

- The new `dokku apps:rename` command. It does not update linked containers, but is useful in many other cases.
- Updated git clone methodology to be more performant for large repositories.
- Moved the dokku-installer from Ruby to Python, allowing us to drop Ruby as a dependency. Python comes with the linux standard base, and should therefore be accessible on more systems.

- #1777: @michaelshobbs Format test labels
- #1782: @michaelshobbs make docker cp work on circleci

## 0.4.3

This release was mainly a documentation release/bugfix.

One major removal was is that as of 0.4.3, we no longer restart containers automatically on failure via docker. This feature was introduced in 0.4.0, and caused issues with duplicate containers being started on server reboot. Until the docker api for container restarts stabilizes, we will not be able to provide this functionality within Dokku.

If desired, you may replicate this functionality using the official `docker-options` plugin.

## 0.4.0

This is our first minor release in almost a year. Many new features and removals have occurred, so here is a neat summary:

- Plugins are now triggered via `plugn`. Notably, you'll need add a `plugin.toml` to describe the plugin as well as use `plugn trigger` instead of `pluginhook` to trigger plugin callbacks. Please see the [plugin creation documentation](http://dokku.viewdocs.io/dokku/development/plugin-creation/) for more details.
- A few new official plugins have been added to the core, including [image tagging](http://dokku.viewdocs.io/dokku/application-deployment/), [certificate management](http://dokku.viewdocs.io/dokku/deployment/ssl-configuration/), a tar-based deploy solution, and much more. Check out the *New Features* section for more details.
- We've removed a few deprecated plugin callbacks. Please see the [plugin triggers documentation](http://dokku.viewdocs.io/dokku/development/plugin-triggers/) to see what is available.
- [Official datastorage plugins](https://github.com/dokku) have been created for the most commonly used datastores. If you previously used/maintained a community contributed plugin, please check these out. We'll be adding more official plugins as time goes on.

Thanks to the *many* contributors for making this release our best release so far, and special thanks to both @michaelshobbs and @Flink for pushing along the `0.4.0` release!
