Milestone: <https://github.com/cobbler/cobbler/milestone/10>

Diff to last release: <https://github.com/cobbler/cobbler/compare/v3.2.1...v3.3.0>

**Known Issues**:

- `cobbler <item> rename` is not working currently
- `cobbler <item> edit` may have bugs due to the internal refactorings

**Breaking Changes**:

- The webinterface got removed [2434](https://github.com/cobbler/cobbler/pull/2434) [#2434](https://github.com/cobbler/cobbler/issues/2286) [#2700](https://github.com/cobbler/cobbler/pull/2700)
- Please use the CLI in the meantime
- A new webinterface is under development at <https://github.com/cobbler/cobbler-web>
- The core code has priority at any time. There are third party tools available which provide a webinterface and use
Cobbler as a backend. A list of those tools can be found at the bottom of the following page: <https://cobbler.github.io/users.html>
- The Cobbler internal TFTP Demon got removed [2512](https://github.com/cobbler/cobbler/pull/2512)
- `yaboot` support got removed as a bootloader for PowerPC [2723](https://github.com/cobbler/cobbler/pull/2723)

**Announcements**:

- Important Security Bugfixes [2794](https://github.com/cobbler/cobbler/pull/2794) [#2795](https://github.com/cobbler/cobbler/issues/2795)
- Arbitrary Read was possible through `generate_script()`
- Arbitrary Write was possible through `upload_log_data()`
- Log poisoning with Remote-Code-Execution was possible through any XMLRPC method which logs to the logfile.
- There was an internal refactoring from runtime created Python attributes to Python Properties. This allows much
better data validation and thus better error handling but also introduced new bugs.

**Breaking Changes**:

- Possibly the settings file is not correctly migrated and needs to be manually adjusted.
- Rename `settings` to `settings.yaml`
- Add all keys which are missing. List will be available in `/var/log/cobbler/cobbler.log`.
- We dropped support for CentOS 7 since no full Python 3 stack is available [2515](https://github.com/cobbler/cobbler/issues/2515)

**Announcement**:

- We will try to fade out Cheetah3 over time. Release 4.0.0 will contain only Jinja2 templates. We will aide and help with the transition and try to make it as smooth as possible
- We will remove the internal implementation of the TFTP daemon with 3.3.0. If you use it, please use one from your system vendor in the future.

This release is a lot about bug fixes and smaller improvements.

**Important**: This will be the last release to contain the already deprecated Django Web Interface.
