v4.2.2

Added

• Added environment grouping and search to the datasource selector on the ticket creation page; already loaded datasources remain selectable when the environment list is incomplete or fails to load (#293).
• Changed online query result caching to use a configurable capacity limit in MB; when the limit is exceeded, results are removed from oldest to newest by last access time, and setting the limit to 0 disables result caching (#301).

Fixed

• Fixed adding the first Feishu or WeCom approval template failing when its template-list configuration did not yet exist (#214).
• Fixed session initialization for GaussDB and other PostgreSQL-family datasources potentially failing to set the isolation level when manual-commit mode had already started a transaction (#323).
• Fixed Feishu SSO not loading the role-mapping configuration, which prevented the default role from taking effect (PR #325).
• Fixed incomplete SQL Server extended-property joins producing duplicate metadata, and plugin driver classes not being loaded correctly (#224, #327).
• Fixed missing statement splitting, behavior analysis, and security analysis for SQL Server TRUNCATE TABLE statements (#234).
• Fixed rule-validation results not being presented correctly in a modal for tickets and the SQL workspace, while preserving rule level, name, violation message, and line information (#328).
• Fixed the table context menu's permission-request action not opening the permission application page (#329).
• Fixed permission-request ticket descriptions incorrectly including requester information (#162).
