## <i class="fa fa-tag"></i> 1.9.0 <i class="fa fa-calendar-o"></i> 2021-09-13
### Security Fixes
- [CVE-2021-39175: XSS vector in slide mode speaker-view](https://github.com/hedgedoc/hedgedoc/security/advisories/GHSA-j748-779h-9697)
- This release removes Google Analytics and Disqus domains from our default Content Security Policy, because they were repeatedly used to exploit security vulnerabilities.  
  If you want to continue using Google Analytics or Disqus, you can re-enable them in the config.
  See [the docs](https://docs.hedgedoc.org/configuration/#web-security-aspects) for details

### Features
- HedgeDoc now automatically retries connecting to the database up to 30 times on startup
- This release introduces the `csp.allowFraming` config option, which controls whether embedding a HedgeDoc instance in other webpages is allowed.
  We **strongly recommend disabling** this option to reduce the risk of XSS attacks
- This release introduces the `csp.allowPDFEmbed` config option, which controls whether embedding PDFs inside HedgeDoc notes is allowed.
  We recommend disabling this option if you don't use the feature, to reduce the attack surface of XSS attacks
- Add additional environment variables to configure the database.
  This allows easier configuration in containerized environments, such as Kubernetes

### Enhancements
- Further improvements to the frontend build process, reducing the initial bundle size by 60%
- Improve the error handling of the `filesystem` upload method
- Improve the error message of failing migrations

### Bugfixes
- Fix crash when trying to read the current Git commit on startup 
- Fix endless loop on shutdown when HedgeDoc can't connect to the database
- Ensure that all cookies are set with the `secure` flag, if HedgeDoc is loaded via HTTPS
- Fix session cookies being created on calls to `/metrics` and `/status`
- Fix incorrect creation of S3 endpoint domain (thanks to [@matejc](https://github.com/matejc))
- Remove CDN support, fixing inconsistencies in library versions delivered to the client
- Fix font display issues when having some variants of fonts used by HedgeDoc installed locally
- Fix links between slides not working
- Fix Vimeo integration using a deprecated API

### Miscellaneous
- Removed MSSQL support, as migrations from 2018 are broken with SQL Server and nobody seems to use it

## <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

## <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

- 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)

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

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

## <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)

## <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.

- 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))
