![*](chapterTOC_bullet.png)
Apama 10.5.3 incorporates the ICU (International Components for Unicode) time-zone data update 2020a, which is the most recent update at the time of release. This will update time-zone data used by the correlator and Time Format EPL plug-in.

You can now enable verbose garbage collection logging and application event logging by using the
--loglevel option of the
correlator executable or by using a YAML configuration file on correlator startup. In previous releases, this was only possible for a running correlator via the
-r option of the
engine_management tool. As a result, these messages are now logged with a
DEBUG prefix when enabled, rather than
INFO. There is also a small change to the format of the messages logged. See also
Viewing garbage collection and application events information.

The REST API and Prometheus now provide statistics information about the number of threads in use by the JVM:
jvmNumThreads (REST API) and
sag_apama_correlator_jvm_num_threads (Prometheus). These statistics will exist when the Java Virtual Machine (JVM) which is embedded in the correlator has been enabled. See also
List of correlator status statistics.
