Dear all,

The Agda Team is very pleased to announce a release candidate of Agda
2.6.2. We plan to release 2.6.2 in a few days.

# Highlights

https://agda.readthedocs.io/en/latest/language/runtime-irrelevance.html).

* Several improvements and bug-fixes related to the JavaScript Backend (
https://agda.readthedocs.io/en/latest/tools/compilers.html#javascript-backend
).

* Added experimental support for Guarded Cubical Agda (
https://agda.readthedocs.io/en/latest/language/guarded-cubical.html).

* The Primitive Sorts (
https://agda.readthedocs.io/en/latest/language/built-ins.html#sorts) of
Agda (`Set` and `Prop`) are no longer keywords and can be renamed when
importing `Agda.Primitive`.

).

* Added support for making System Calls (

from the reflection API.
