## Why did you switch from MathJax to KaTeX?
|
|
|
|
The new react frontend, that was introduced with HedgeDoc 2.0 switched from MathJax 2
|
|
to [KaTeX][katex], because:
|
|
|
|
- [KaTeX is much faster than MathJax](https://www.intmath.com/cg5/katex-mathjax-comparison.php?processor=MathJax )
|
|
- [The MathJax React Component is not maintained and doesn't support MathJax 3](https://github.com/wko27/react-mathjax)
|
|
- [KaTeX supports every command you'll need for math expressions](https://katex.org/docs/supported.html)
|
|

## Why are code-blocks with 'sequence' as language deprecated?
|
|
|
|
Starting with HedgeDoc 2.0, mermaid is used for rendering sequence-diagrams.
|
|
The [syntax][mermaid-syntax] doesn't change. To remove the deprecation warning, simply change the
|
|
codeblock-"language" from `sequence` to `mermaid` and insert a single line with `sequenceDiagram`
|
|
just before your diagram content.
|
|
|
|
**Deprecated**:
|
|
|
|
```sequence
|
|
Alice->>John: Hello John, how are you?
|
|
John-->>Alice: Great!
|
|
```
|
|
|
|
**New**:
|
|
|
|
```mermaid
|
|
sequenceDiagram
|
|
Alice->>John: Hello John, how are you?
|
|
John-->>Alice: Great!
|
|
```
|

|
## Why do tags in headings don't work anymore?
|
|
|
|
Starting with HedgeDoc 2.0, we don't support tag headings in the note anymore.
|
|
|
|
```markdown
|
|
#### tags: `tag1`, `tag2`
|
|
```
|
|
|
|
Instead, please use the [frontmatter metadata][frontmatter] to specify tags.
|
|
|
|
[frontmatter]: https://demo.hedgedoc.org/yaml-metadata#tags
|
|
|
|
## Why is the comma separated definition of tags in the YAML-metadata deprecated?
|
|
|
|
[YAML already has a definition for lists](https://yaml.org/spec/1.2/spec.html#id2759963).
|
|
Therefore, we don't see any reason to maintain another way to define a list.
|
|
|
|
<!-- markdownlint-disable no-emphasis-as-heading -->
|
|
**Deprecated**
|
|
<!-- markdownlint-enable no-emphasis-as-heading -->
|
|
|
|
```yaml
|
|
tags: tag1, tag2
|
|
```
|
|
|
|
<!-- markdownlint-disable no-emphasis-as-heading -->
|
|
**New**
|
|
<!-- markdownlint-enable no-emphasis-as-heading -->
|
|
|
|
```yaml
|
|
tags:
|
|
- tag1
|
|
- tag2
|
|
```
|
|
|
|
<!-- markdownlint-disable no-emphasis-as-heading -->
|
|
*or*
|
|
<!-- markdownlint-enable no-emphasis-as-heading -->
|
|
|
|
```yaml
|
|
tags: ['tag1', 'tag2']
|
|
```
|
|
|
|
## Why should I want to run my renderer on a different (sub-)domain?
|
|
|
|
If the renderer is provided by another domain, it's way harder to manipulate HedgeDoc or
|
|
steal credentials from the rendered note content, because renderer and editor are more isolated.
|
|
This increases the security of the software and greatly mitigates [XSS attacks][xss].
|
|
However, you can run HedgeDoc without this extra security, but we recommend using it if possible.
|
|
|
|
!!! note
|
|
When you want to use a separate domain for `HD_RENDERER_BASE_URL`, your reverse proxy config
|
|
needs to be adjusted to direct requests for this domain to the frontend.

## Why are forkawesome icons deprecated?
|
|
|
|
As forkawesome icons are not really well maintained, we decided to replace them with
|
|
[bootstrap icons][bootstrap-icons]. To keep the compatibility with HedgeDoc 1 notes
|
|
we still import them, but will likely remove those icons at some point. So your
|
|
best take of action is replacing these icons with [bootstrap icons][bootstrap-icons].
