Released:    Tue Dec 29 12:24:45 2020
Summary:     Recommended update for libxml2
Type:        recommended
Severity:    moderate
References:  1178823
This update for libxml2 fixes the following issues:

Avoid quadratic checking of identity-constraints, speeding up XML validation (bsc#1178823)
* key/unique/keyref schema attributes currently use quadratic loops
  to check their various constraints (that keys are unique and that
  keyrefs refer to existing keys).
* This fix uses a hash table to avoid the quadratic behaviour.
