new thrift method is available to test if a session is reserved and deletes
it if it is not reserved
without creating an additional thread. If the new method is not available
it falls back to the previous
close method to preserve interoperability between 2.x versions.
+* {% ghi 3738 %} Adds parameter {% plink gc.remove.in.use.candidates %}, that
enables the Garbage Collector

expected to increase the speed of

+* {% ghi 3756 %} Added new RPC named cancelUpdate that reduces the amount of
threads waiting to close failed

performance

the same host to leverage
