MySQL Router 8.4 Release Notes
This release is no longer available for download. It was removed due to a dependency on a version of the server which is also no longer available for download. See MySQL 8.4.1 Release Notes. Please upgrade to MySQL Router 8.4.2 instead.
System variable changes were not propagated when read-write splitting was enabled. (Bug #36674083)
Current schema changes were not propagated to shared connections when both read-write splitting and connection sharing were enabled. (Bug #36663727)
MySQL Router always updates the last_check_in in
the Metadata Schema when it starts, even if the Cluster is
INVALIDATED, leading to an errant
transaction. As of this release, MySQL Router does not update
last_check_in if the Cluster is
INVALIDATED.
(Bug #36563430)
Increased the maximum
router_id value from 999999
to 4294967295 (2^32-1). This also affects how the internal
metadata_cache
user
name is defined.
