v0.85

SQL

• Add mz_internal.mz_recent_activity_log to the system catalog. This view contains a log of the SQL statements that have been issued to Materialize in the past 3 days, along with various metadata about them. Querying this view is typically much faster than querying mz_internal.mz_activity_log.

Bug fixes and other improvements

• Fix a bug where DISCARD ALL did not consider system or role defaults {{% gh 24601 %}}.

• Fix a bug causing the mz_monitor and mz_monitor_redacted system roles to not show up in the mz_roles system catalog table {{% gh 24617 %}}.
