+
+The new flag `--querylog-sample-rate float` adds support for sampling queries based on a float value between 0.0 _(no logging)_ and 1.0 _(all queries logged)_. If configured, this filtering is applied after the existing `--querylog-filter-tag` filter.

+
+The new flag `--tablet-filter-tags StringMap` adds support to VTGate for filtering tablets by tablet tag key/values, specified as comma-separated list of key:values. The tags of a tablet are defined by the VTTablet flag `--init_tags`, which is also defined as a comma-separated list of key:values.
