As mentioned in https://www.php.net/manual/en/function.basename.php both
basename() and dirname() are locale aware.
An incorrect locale can cause the page tree to behave in strange ways.
For example the structure
/über-uns
|-index.md
|-impressum.md
could lead to the page impressum not being a child of über-uns.

* [New] Kick-start development of Pico 3.0
* [Changed] Require PHP 7.0.8+
* [Changed] Update dependencies: Twig 2.12, Symfony YAML 3.4, Parsedown 1.7.4
and Parsedown Extra 0.8.1; this is just an interim step, we'll
update to Twig 3.0+ and Symfony YAML 5.0+ later
```
```
* [Fixed] Require Parsedown 1.8.0-beta-7 and Parsedown Extra 0.8.0-beta-1 due
to changes in Parsedown and Parsedown Extra breaking BC beyond repair
* [Changed] #523: Check for hidden pages based on page ID instead of full paths
* [Changed] Improve Pico docs
```
A few days ago Parsedown released new ("stable") versions of Parsedown and Parsedown Extra: Parsedown 1.7.4 and Parsedown Extra 0.8.1. Parsedown 1.7.4 backports some features of Parsedown 1.8.0-beta-7 and is compatible with Parsedown Extra 0.8.1. However, due to these changes Parsedown Extra 0.8.1 now breaks compatibility with Parsedown 1.8.0-beta-7. Parsedown's release process is messed up beyond repair... Not sure what we're going to do now, this needs some research whether we can downgrade to Parsedown 1.7.4 without breaking things (what would require us to release a new major release, i.e. Pico 3.0). For now we're pinning Parsedown 1.8.0-beta-7 and Parsedown Extra 0.8.0-beta-1 as of Pico 2.1.0.
