# Release Notes

## <i class="fa fa-tag"></i> 1.7.0-rc2 <i class="fa fa-calendar-o"></i> 2020-12-02
Changes since 1.7.0-rc1:

### Bugfixes
- Fix crash when OAuth2 config parameters are missing (thanks to [@vberger](https://github.com/vberger) for reporting!)
- Handle broken `SequelizeMeta` table on MySQL/MariaDB (thanks to [@titulebolide](https://github.com/titulebolide) for reporting!)


## <i class="fa fa-tag"></i> 1.7.0-rc1 <i class="fa fa-calendar-o"></i> 2020-11-29

We have renamed to HedgeDoc!
Many thanks to [Éric Gaspar](https://github.com/ericgaspar/) who designed our new logo!
Have a look at our new website (which also explains the reasoning behind the renaming) at https://hedgedoc.org

This is probably the last release in the 1.x series. Stay tuned for 2.0, scheduled for release next year.

**Please note:** This release dropped support for Node 8, which is end-of-life since January 2020. You now need at least Node 10.13 to run HedgeDoc, but we recommend running [the latest LTS release](https://nodejs.org/en/about/releases/).

### Enhancements
- Our release tarballs now contain the frontend bundle. This saves users from building the frontend themselves, which was an issue on memory-constrained systems.
- Add OIDC scopes for email & profile retrieval ([#278](https://github.com/hedgedoc/hedgedoc/pull/278) & [#419](https://github.com/hedgedoc/hedgedoc/pull/419) by [@elespike](https://github.com/elespike) & [@vberger](https://github.com/vberger))
- Allow to set a SAML client certificate ([#350](https://github.com/hedgedoc/hedgedoc/pull/350) by [@n0emis](https://github.com/n0emis) & [@em0lar](https://github.com/em0lar))
- Add YunoHost docs ([#431](https://github.com/hedgedoc/hedgedoc/pull/431) by [@ericgaspar](https://github.com/ericgaspar))
- Set OAuth2 `state` parameter ([#407](https://github.com/hedgedoc/hedgedoc/pull/407) & [#541](https://github.com/hedgedoc/hedgedoc/pull/541) by [@dalcde](https://github.com/dalcde) & [@haslersn](https://github.com/haslersn))
- Various documentation improvements (by [@oupala](https://github.com/oupala), [@autra](https://github.com/autra) & [@AdamWorley](https://github.com/AdamWorley))
- Add migration script for minio ([#499](https://github.com/hedgedoc/hedgedoc/pull/499) by [@pierreozoux](https://github.com/pierreozoux))
- Add authorization for OAuth ([#595](https://github.com/hedgedoc/hedgedoc/pull/595) by [@joachimmathes](https://github.com/joachimmathes))
- Improvements to our cookie handling
- Compatibility with Node 14
- Translation updates
- Various dependency updates

### Bugfixes
- Fix compatibility with upper-case MIME-types ([#509](https://github.com/hedgedoc/hedgedoc/pull/509) by [@pierreozoux](https://github.com/pierreozoux))
- Add fix for missing deletion of notes on user-deletion request
- Fix relative path for fetching the style when set 
- Fix broken redirect on login
- CSS fixes for slide mode
- Do not create new notes with `null` as content
