Previously in werk 17982, Checkmk applied a file upload restriction of 100MB to 2.5.0 as part of our ongoing security hardening practices. This restriction has forced some users to manually update their sites' Apache LimitRequestBody in order to update Checkmk.

As of this werk, this limit has been loosened to 1GB by default. This new limit should mitigate the risk of an update failing due a 413 Request Entity Too Large error.
