# Release Notes
## <i class="fa fa-tag"></i> 1.8.2 <i class="fa fa-calendar-o"></i> 2021-05-11

This release fixes two security issues. We recommend upgrading as soon as possible.

### Security Fixes
- [CVE-2021-29503: Improper Neutralization of Script-Related HTML Tags in Notes](https://github.com/hedgedoc/hedgedoc/security/advisories/GHSA-gjg7-4j2h-94fq)
- Fix a potential XSS-vector in the handling of usernames and profile pictures

## <i class="fa fa-tag"></i> 1.8.1 <i class="fa fa-calendar-o"></i> 2021-05-06
### Enhancements
- Speed up `yarn install` in production mode (as performed by `bin/setup`) by marking frontend-only dependencies as dev-dependencies.
  This also reduces the size of the docker container
- Speed up the frontend-build by using `esbuild` instead of `terser` to minify JavaScript
- Improve behavior of the 'Quote', 'List', 'Unordered List' and 'Check List' buttons in the editor to automatically
  apply to the complete first and last line of the selection

### Bugfixes
- Correct the 1.8.0 release notes to state that CVE-2021-29475 has been fixed since HedgeDoc 1.5.0.
- Fix crash on startup when `useSSL` or `csp.upgradeInsecureRequests` is enabled (thanks to [@mdegat01](https://github.com/mdegat01) for reporting)
- Automatically enable `protocolUseSSL` when `useSSL` is also enabled
- Fix the 'Quote', 'List', 'Unordered List' and 'Check List' buttons in the editor to not duplicate content
  when only parts of a line are selected (thanks to [@AnomalRoil](https://github.com/AnomalRoil) for reporting)
- Fix click handler for numbered task lists (thanks to [@xoriade](https://github.com/xoriade) for reporting)


## <i class="fa fa-tag"></i> 1.8.0 <i class="fa fa-calendar-o"></i> 2021-05-03

This release fixes multiple security issues. We recommend upgrading as soon as possible.

**Please note:** This release dropped support for Node 10, which is end-of-life since April 2021. You now need at least Node 12 to run HedgeDoc, but we recommend running [the latest LTS release](https://nodejs.org/en/about/releases/).

### Security Fixes
- [CVE-2021-29474: Relative path traversal Attack on note creation](https://github.com/hedgedoc/hedgedoc/security/advisories/GHSA-p528-555r-pf87)
- [CVE-2021-21306: Underscore ReDoS](https://github.com/markedjs/marked/security/advisories/GHSA-4r62-v4vq-hr96) in the `marked` library  
  This issue allowed an attacker to hang HedgeDoc by inserting a malicious string into a note. Thanks to Ralph Krimmel for reporting!

We also published an advisory for [CVE-2021-29475: PDF export allows arbitrary file reads](https://github.com/hedgedoc/hedgedoc/security/advisories/GHSA-pxxg-px9v-6qf3),  
which has already been fixed since HedgeDoc 1.5.0.

### Features
- Database migrations are now automatically applied on application startup  
  The separate `.sequelizerc` configuration file is no longer necessary and can be safely deleted
- A Prometheus-endpoint is now available at `/metrics`, exposing the same stats as `/status`
  in addition to various Node.js performance figures
- Add a config option to require authentication in FreeURL mode ([#755](https://github.com/hedgedoc/hedgedoc/pull/755) by [@nidico](https://github.com/nidico))

### Enhancements
- Removed dependency on external imgur library
- HTML language tags are now set up in a way that stops Google Translate from translating note contents while editing
- Removed `yahoo.com` from the default content security policy
- New translations for Bulgarian, Persian, Galician, Hebrew, Hungarian, Occitan and Brazilian Portuguese  
  Updated translations for Arabic, English, Esperanto, Spanish, Hindi, Japanese, Korean, Polish, Portuguese, Turkish and Traditional Chinese
  Thanks to all translators!
- Various dependency updates

### Bugfixes
- Improve readability of diagrams & embeddings in night-mode
- Use the default template for new notes in FreeURL mode
- Fix frontend-crash in slide-mode if no `slideOptions` are present in the frontmatter
- Return 404 on the `/download` route for non-existent notes in FreeURL mode
- Properly clean up the UNIX socket on application exit
- Don't overwrite existing notes on POST-requests to `/new/<alias>` in FreeURL mode

## <i class="fa fa-tag"></i> 1.7.2 <i class="fa fa-calendar-o"></i> 2021-01-15
This release fixes a security issue. We recommend upgrading as soon as possible.
### Security Fixes
- [CVE-2021-21259: Stored XSS in slide mode](https://github.com/hedgedoc/hedgedoc/security/advisories/GHSA-44w9-vm8p-3cxw)  
  An attacker can inject arbitrary JavaScript into a HedgeDoc note.

### Bugfixes
- Ensure the last line of the markdown editor is not covered by the status bar (thanks to [@mhdrone](https://github.com/mhdrone) for reporting!)

## <i class="fa fa-tag"></i> 1.7.1 <i class="fa fa-calendar-o"></i> 2020-12-27
This release fixes two security issues. We recommend upgrading as soon as possible.
### Security Fixes
- [CVE-2020-26286: Arbitrary file upload](https://github.com/hedgedoc/hedgedoc/security/advisories/GHSA-wcr3-xhv7-8gxc)  
  An unauthenticated attacker can upload arbitrary files to the upload storage backend.
- [CVE-2020-26287: Stored XSS in mermaid diagrams](https://github.com/hedgedoc/hedgedoc/security/advisories/GHSA-g6w6-7xf9-m95p)  
  An attacker can inject arbitrary script tags in HedgeDoc notes using mermaid diagrams.


## <i class="fa fa-tag"></i> 1.7.0 <i class="fa fa-calendar-o"></i> 2020-12-21

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/).

**Please note:** If you use a reverse proxy and TLS, make sure it sets the `X-Forwarded-Proto` header correctly,
otherwise you will encounter login-issues.
[Our docs](https://github.com/hedgedoc/hedgedoc/blob/72734690225bb431908b0d4bd8edf38576a95f2f/docs/setup/reverse-proxy.md#reverse-proxy-config) have example configs for common reverse proxies. 

### 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
