New and noteworthy

Updated Apex Support

• The Apex language support has been bumped to version 50 (Winter '21). All new language features are now properly
  parsed and processed. Especially the Safe Navigation Operator is now supported.
  See also Salesforce Winter '21 Release Notes

New Rules

• The new Apex rule OperationWithLimitsInLoop (apex-performance)
  finds operations in loops that may hit governor limits such as DML operations, SOQL
  queries and more. The rule replaces the three rules "AvoidDmlStatementsInLoops", "AvoidSoqlInLoops",
  and "AvoidSoslInLoops".

Renamed Rules

• The Java rule DoNotCallSystemExit has been renamed to
  DoNotTerminateVM, since it checks for all the following calls:
  System.exit(int), Runtime.exit(int), Runtime.halt(int). All these calls terminate
  the Java VM, which is bad, if the VM runs an application server which many independent applications.

Deprecated Rules

• The Apex rules AvoidDmlStatementsInLoops,
  AvoidSoqlInLoops and AvoidSoslInLoops
  (apex-performance) are deprecated in favour of the new rule
  OperationWithLimitsInLoop. The deprecated rules will be removed
  with PMD 7.0.0.
