When I try to upgrade to a v5.1, composer can't find release:

Your requirements could not be resolved to an installable set of packages.
Problem 1
    - Root composer.json requires exercise/htmlpurifier-bundle 5.1.*, found exercise/htmlpurifier-bundle[dev-master, v0.1.0, ..., 0.9.x-dev, v1.0.0, 1.0.x-dev, v2.0.0-BETA1, ..., 2.0.x-dev, v3.0-beta, ..., 3.x-dev, 4.0, ..., 4.x-dev, v5.0-BETA1, 5.0, 5.x-dev (alias of dev-master)] but it does not match the constraint.

@Evgeny1973 there is no auto update on packagist for this repository. We need to wait a few days before I can update it manually as it did not work yesterday :/.

@Evgeny1973 5.1 is available through packagist 🎉, cheers!
