Hi All!
We have just published the first `beta` of the `1.4.0` release cycle!
This means that we are now satisfied with the new features that have been
added so we will now focus mostly on bug fixing and making sure all our
users can migrate safely from `1.3.7` to the new version.
Here's a quick run-down of some of the major changes since `1.3.7`:
* UTF8 support has been added to script parsing. This means that you can
now do things like this:
```
🎵 = playlist("~/Music")
def f(_) =
[("title","Ma chanson preferée! 🙂")]
end
🎵 = map_metadata(f,🎵)
```
Variable names can be:
- strings of alphabetic characters with underscore, dots and single
quotes Ex: `ma_sourcepreferée.'foo'`
- Single math and other symbols
Things like:
```
∞ = "foo"
💰 = "bling bling"
```
More importantly, as exemplified above, you can now write utf8 strings
in your script. This should make it much more convenient to write
functions handling metadata using non-ascii characters, which happens
a lot with our international users/artists.
* External process executions are now sandboxed using `bwrap` when detected
at compile time. This should guarantee more safety during process
executions. By default, file system is acessible `read-only` except for the
temporary directory and network is accessible.
* HLS input and output support with `output.file.hls`, `output.harbor.hls`
and `input.hls`
* `cross`/`crossfade` operators are removed,
`smart_cross`/`smart_crossfade` are renamed `cross`/`crossfade`.
`override_duration` feature has been ported to the new `cross` and metadata
label for it is now `"liq_cross_duration"`
The full changelog is getting big now so the rest is included below.
We strongly recommend users to test their script as early as possible with
this `beta` in order to let us know if we are missing any important feature
and also if any issue/bug arises. You can test using `opam` this way:
```
git clone https://github.com/savonet/liquidsoap.git
cd liquidsoap
git checkout 1.4.0-beta1
opam pin add .
```
Please note that you may also need to `pin` some of `liquidsoap`'s
dependencies. The `configure` script should let you know those that are
required.
Finally, I would like to point out our new slack workspace! We are moving
most user and developers discussions over there so feel free to give it a
try at http://slak.liquidsoap.info
Hope y'all enjoy this first `beta` release!
