+
+* [#4544](https://github.com/icinga/icinga2/issues/4544) (Notifications): Icinga 2 sends recovery notifications for SOFT NOT-OK states
+
+## 2.5.0 (2016-08-23)
+
+### Notes
+
+* InfluxdbWriter feature
+* API
+ * New endpoints: /v1/variables and /v1/templates (GET requests), /v1/action/generate-ticket (POST request)
+ * State/type filters for notifications/users are now string values (PUT, POST, GET requests)
+* Configuration
+ * TimePeriod excludes/includes attributes
+ * DateTime object for formatting time strings
+ * New prototype methods: Array#filter, Array#unique, Array#map, Array#reduce
+ * icinga2.conf now includes plugins-contrib, manubulon, windows-plugins, nscp by default (ITL CheckCommand definitions)
+ * Performance improvements (config compiler and validation)
+* CLI
+ * 'icinga2 object list' formats state/type filters as string values
+ * Compiled config files are now visible with "notice" debug level (hidden by default)
+ * CA serial file now uses a hash value (HA cluster w/ 2 CA directories)
+* Cluster
+ * There is a known issue with >2 endpoints inside a zone. Icinga 2 will now log a warning.
+ * Support for accepted ciphers and minimum TLS version
+ * Connection and error logging has been improved.
+* DB IDO
+ * Schema upgrade required (2.5.0.sql)
+ * Incremental config dump (performance boost)
+ * `categories` attribute is now an array. Previous method is deprecated and to be removed.
+ * DbCatLog is not enabled by default anymore.
+ * SSL support for MySQL
+* New packages
+ * vim-icinga2 for syntax highlighting
+ * libicinga2 (Debian), icinga2-libs (RPM) for Icinga Studio packages

+
+## <a id="contributing-intro"></a> Introduction
+
+Please consider our [roadmap](https://github.com/Icinga/icinga2/milestones) and
+[open issues](https://github.com/icinga/icinga2/issues) when you start contributing
+to the project.
+Issues labeled with [help wanted](https://github.com/Icinga/icinga2/labels/help%20wanted) or
+[good first issue](https://github.com/Icinga/icinga2/labels/good%20first%20issue) will
+help you get started more easily.
+
+Before starting your work on Icinga 2, you should [fork the project](https://help.github.com/articles/fork-a-repo/)
+to your GitHub account. This allows you to freely experiment with your changes.
+When your changes are complete, submit a [pull request](https://help.github.com/articles/using-pull-requests/).
+All pull requests will be reviewed and merged if they suit some general guidelines:
+
+* Changes are located in a topic branch
+* For new functionality, proper tests are written
+* Changes should follow the existing coding style and standards
+
+Please continue reading in the following sections for a step by step guide.
+
+## <a id="contributing-fork"></a> Fork the Project
+
+[Fork the project](https://help.github.com/articles/fork-a-repo/) to your GitHub account
+and clone the repository:
+
+```
+git clone git@github.com:dnsmichi/icinga2.git
+cd icinga2
+```
+
+Add a new remote `upstream` with this repository as value.
+
+```
+git remote add upstream https://github.com/icinga/icinga2.git
+```
+
+You can pull updates to your fork's master branch:
+
+```
+git fetch --all
+git pull upstream HEAD
+```
+
+Please continue to learn about [branches](CONTRIBUTING.md#contributing-branches).
+
+## <a id="contributing-branches"></a> Branches
+
+Choosing a proper name for a branch helps us identify its purpose and possibly
+find an associated bug or feature.
+Generally a branch name should include a topic such as `bugfix` or `feature` followed
+by a description and an issue number if applicable. Branches should have only changes
+relevant to a specific issue.
+
+```
+git checkout -b bugfix/service-template-typo-1234
+git checkout -b feature/config-handling-1235
+```
+
+Continue to apply your changes and test them. More details on specific changes:
+
+* [Source Code Patches](#contributing-patches-source-code)
+* [Documentation Patches](#contributing-patches-documentation)
+* [Contribute CheckCommand Definitions](#contributing-patches-itl-checkcommands)
+
+## <a id="contributing-commits"></a> Commits
+
+Once you've finished your work in a branch, please ensure to commit
+your changes. A good commit message includes a short topic, additional body
+and a reference to the issue you wish to solve (if existing).
+
+Fixes:
+
+```
+Fix problem with notifications in HA cluster
+
+There was a race condition when restarting.
+
+refs #4567
+```
+
+Features:
+
+```
+Add ITL CheckCommand printer
+
+Requires the check_printer plugin.
+
+refs #1234
+```
+
+You can add multiple commits during your journey to finish your patch.
+Don't worry, you can squash those changes into a single commit later on.
+
+## <a id="contributing-pull-requests"></a> Pull Requests
+
+Once you've commited your changes, please update your local master
+branch and rebase your bugfix/feature branch against it before submitting a PR.
+
+```
+git checkout master
+git pull upstream HEAD
+
+git checkout bugfix/notifications
+git rebase master
+```
+
+Once you've resolved any conflicts, push the branch to your remote repository.
+It might be necessary to force push after rebasing - use with care!
+
+New branch:
+```
+git push --set-upstream origin bugfix/notifications
+```
+
+Existing branch:
+```
+git push -f origin bugfix/notifications
+```
+
+You can now either use the [hub](https://hub.github.com) CLI tool to create a PR, or nagivate
+to your GitHub repository and create a PR there.
+
+The pull request should again contain a telling subject and a reference
+with `fixes` to an existing issue id if any. That allows developers
+to automatically resolve the issues once your PR gets merged.
+
+```
+hub pull-request
+
+<a telling subject>
+
+fixes #1234
+```
+
+Thanks a lot for your contribution!
+
+
+### <a id="contributing-rebase"></a> Rebase a Branch
+
+If you accidentally sent in a PR which was not rebased against the upstream master,
+developers might ask you to rebase your PR.
+
+First off, fetch and pull `upstream` master.
+
+```
+git checkout master
+git fetch --all
+git pull upstream HEAD
+```
+
+Then change to your working branch and start rebasing it against master:
+
+```
+git checkout bugfix/notifications
+git rebase master
+```
+
+If you are running into a conflict, rebase will stop and ask you to fix the problems.
+
+```
+git status
+
+ both modified: path/to/conflict.cpp
+```
+
+Edit the file and search for `>>>`. Fix, build, test and save as needed.
+
+Add the modified file(s) and continue rebasing.
+
+```
+git add path/to/conflict.cpp
+git rebase --continue
+```
+
+Once succeeded ensure to push your changed history remotely.
+
+```
+git push -f origin bugfix/notifications
+```
+
+
+If you fear to break things, do the rebase in a backup branch first and later replace your current branch.
+
+```
+git checkout bugfix/notifications
+git checkout -b bugfix/notifications-rebase
+
+git rebase master
+
+git branch -D bugfix/notifications
+git checkout -b bugfix/notifications
+
+git push -f origin bugfix/notifications
+```
+
+### <a id="contributing-squash"></a> Squash Commits
+
+> **Note:**
+>
+> Be careful with squashing. This might lead to non-recoverable mistakes.
+>
+> This is for advanced Git users.
+
+Say you want to squash the last 3 commits in your branch into a single one.
+
+Start an interactive (`-i`) rebase from current HEAD minus three commits (`HEAD~3`).
+
+```
+git rebase -i HEAD~3
+```
+
+Git opens your preferred editor. `pick` the commit in the first line, change `pick` to `squash` on the other lines.
+
+```
+pick e4bf04e47 Fix notifications
+squash d7b939d99 Tests
+squash b37fd5377 Doc updates
+```
+
+Save and let rebase to its job. Then force push the changes to the remote origin.
+
+```
+git push -f origin bugfix/notifications
+```
+
+
+## <a id="contributing-testing"></a> Testing
+
+Basic unit test coverage is provided by running `make test` during package builds.
+Read the [INSTALL.md](INSTALL.md) file for more information about development builds.
+
+Snapshot packages from the latest development branch are available inside the
+[package repository](https://packages.icinga.com).
+
+You can help test-drive the latest Icinga 2 snapshot packages inside the
+[Icinga 2 Vagrant boxes](https://github.com/icinga/icinga-vagrant).
+
+
+## <a id="contributing-patches-source-code"></a> Source Code Patches
+
+Icinga 2 is written in C++ and uses the Boost libraries. We are also using the C++11 standard where applicable (please
+note the minimum required compiler versions in the [INSTALL.md](INSTALL.md) file.
+
+Icinga 2 can be built on Linux/Unix nodes and Windows clients. In order to develop patches for Icinga 2,
+you should prepare your own local build environment and know how to work with C++.
+
+More tips:
+
+* Requirements and source code installation for Linux/Unix is explained inside the [INSTALL.md](INSTALL.md) file.
+* Debug requirements and GDB instructions can be found in the [documentation](https://github.com/Icinga/icinga2/blob/master/doc/20-development.md).
+* If you are planning to develop and debug the Windows client, setup a Windows environment with [Visual Studio](https://www.visualstudio.com/vs/community/). An example can be found in [this blogpost](https://blog.netways.de/2015/08/24/developing-icinga-2-on-windows-10-using-visual-studio-2015/).
+
+## <a id="contributing-patches-documentation"></a> Documentation Patches
+
+The documentation is written in GitHub flavored [Markdown](https://guides.github.com/features/mastering-markdown/).
+It is located in the `doc/` directory and can be edited with your preferred editor. You can also
+edit it online on GitHub.
+
+```
+vim doc/2-getting-started.md
+```
+
+In order to review and test changes, you can install the [mkdocs](http://www.mkdocs.org) Python library.
+
+```
+pip install mkdocs
+```
+
+This allows you to start a local mkdocs viewer instance on http://localhost:8000
+
+```
+mkdocs serve
+```
+
+Changes on the chapter layout can be done inside the `mkdocs.yml` file in the main tree.
+
+There also is a script to ensure that relative URLs to other sections are updated. This script
+also checks for broken URLs.
+
+```
+./doc/update-links.py doc/*.md
+```
+
+## <a id="contributing-patches-itl-checkcommands"></a> Contribute CheckCommand Definitions
+
+The Icinga Template Library (ITL) and its plugin check commands provide a variety of CheckCommand
+object definitions which can be included on-demand.
+
+Advantages of sending them upstream:
+
+* Everyone can use and update/fix them.
+* One single place for configuration and documentation.
+* Developers may suggest updates and help with best practices.
+* You don't need to care about copying the command definitions to your satellites and clients.
+
+#### <a id="contributing-itl-checkcommands-start"></a> Where do I start?
+
+Get to know the check plugin and its options. Read the general documentation on how to integrate
+your check plugins and how to create a good CheckCommand definition.
+
+A good command definition uses:
+
+* Command arguments including `value`, `description`, optional: `set_if`, `required`, etc.
+* Comments `/* ... */` to describe difficult parts.
+* Command name as prefix for the custom attributes referenced (e.g. `disk_`)
+* Default values
+ * If `host.address` is involved, set a custom attribute (e.g. `ping_address`) to the default `$address$`. This allows users to override the host's address later on by setting the custom attribute inside the service apply definitions.
+ * If the plugin is also capable to use ipv6, import the `ipv4-or-ipv6` template and use `$check_address$` instead of `$address$`. This allows to fall back to ipv6 if only this address is set.
+ * If `set_if` is involved, ensure to specify a sane default value if required.
+* Templates if there are multiple plugins with the same basic behaviour (e.g. ping4 and ping6).
+* Your love and enthusiasm in making it the perfect CheckCommand.
+
+#### <a id="contributing-itl-checkcommands-overview"></a> I have created a CheckCommand, what now?
+
+Icinga 2 developers love documentation. This isn't just because we want to annoy anyone sending a patch,
+it's a matter of making your contribution visible to the community.
+
+Your patch should consist of 2 parts:
+
+* The CheckCommand definition.
+* The documentation bits.
+
+[Fork the repository](https://help.github.com/articles/fork-a-repo/) and ensure that the master branch is up-to-date.
+
+Create a new fix or feature branch and start your work.
+
+```
+git checkout -b feature/itl-check-printer
+```
+
+#### <a id="contributing-itl-checkcommands-add"></a> Add CheckCommand Definition to Contrib Plugins
+
+There already exists a defined structure for contributed plugins. Navigate to `itl/plugins-contrib.d`
+and verify where your command definitions fits into.
+
+```
+cd itl/plugins-contrib.d/
+ls
+```
+
+If you want to add or modify an existing Monitoring Plugin please use `itl/command-plugins.conf` instead.
+
+```
+vim itl/command-plugins-conf
+```
+
+##### Existing Configuration File
+
+Just edit it, and add your CheckCommand definition.
+
+```
+vim operating-system.conf
+```
+
+Proceed to the documentation.
+
+##### New type for CheckCommand Definition
+
+Create a new file with .conf suffix.
+
+```
+ $ vim printer.conf
+```
+
+Add the file to `itl/CMakeLists.txt` in the FILES line in **alpha-numeric order**.
+This ensures that the installation and packages properly include your newly created file.
+
+```
+vim CMakeLists.txt
+
+-FILES ipmi.conf network-components.conf operating-system.conf virtualization.conf vmware.conf
++FILES ipmi.conf network-components.conf operating-system.conf printer.conf virtualization.conf vmware.conf
+```
+
+Add the newly created file to your git commit.
+
+```
+git add printer.conf
+```
+
+Do not commit it yet but finish with the documentation.
+
+#### <a id="contributing-itl-checkcommands-docs"></a> Create CheckCommand Documentation
+
+Edit the documentation file in the `doc/` directory. More details on documentation
+updates can be found [here](CONTRIBUTING.md#contributing-documentation).
+
+```
+vim doc/10-icinga-template-library.md
+```
+
+The CheckCommand documentation should be located in the same chapter
