Let’s continue with a new release in this Slipshow thread. It’s my _ginormous pleasure_ to announce the [opam release](https://github.com/ocaml/opam-repository/pull/28128) of:

## Slipshow v0.3.0: The return of the subslips

As you can see, a crucial improvement is that releases are now named. Semver is boring, let’s add a bit of fun in a serious world.

The release name subtly suggests that subslips are back. Yes, subslips are back! Slipshow allows your presentation to be visually organized. Subslips are slips that are inside a slip. You can then “enter” it, go through it, and exit it to go back to the original slip.

But a gif is worth a ginormous word, so here it is:

To obtain a similar effect, using the new release, you can simply do:

```markdownopam
We will discuss three topics:

{style="display:flex" children:slip}
----
# Topic 1

Content of the first topic

---
# Topic 2

Content of the second topic

---
# Topic 3

Content of the third topic

```

If you want to separate the source in multiple file, it’s easy: `{include src="file/to/include.md"}`. And did you notice that `---` now act as group separators? At this point, let me just output the changelog (highligting some of them):

### Compiler

- **Fix file watching issues** by vendoring a (modified) irmin-watcher, and watching  
all files the presentation depends on (images, themes, …) (#113)
- Adds a favicon to the presentation file ( **Slipshow now has a logo!** ) (#115)
- Fix missing attributes on images (#117)
- Fix missing mime type on images that made svg undisplayable (#120)
- Fix detection of math inside inline attributes (#124)
- **Add `--dimension` to specify the dimension of the presentation (#131)**
- Add less boring name for versions (#132)

### Language

- **Add `{include src="path/to/file.md"}` to include a file in another (#114)**
- Allow `pause` to have a target (#118)
- Remove the need for `step` to execute actions (#118)
- **Added support for subslips and slides (#118)**
- Added pause blocks (#127)
- **Use horizontal lines (`---`) to group blocks (#129)**
- Pass attributes to children with `children:` (#130)
- Consistently remove the need for `-at-unpause` (#133)

### Engine

- Simplify table of content by removing preview (#118)
- **Fix wrong computation of location (#118, #119)**
- **Improve zooming behaviour (everywhere) and performance (on chrome-based browsers…) (#121)**
  - If someone has some expertise on how to improve performance on firefox, I’m interested!

- Add PageUp and PageDown as navigation keys, adding support for pointers (#126)
