upgrade note

• For the Date/DatetimeV2 type, in the result of the DESCRIBLEAND SHOW CREATE TABLEstatement, it will no longer be displayed as Date/DatetimeV2, but directly displayed as Date/Datetime. (This change is for compatibility with some BI systems. If you want to check the actual type of the column, you can DESCRIBE ALLcheck it with a statement.)
• When querying information_schematables in the library, the meta information in the External Catalog is no longer returned by default. (This change avoids information_schemathe problem that the library cannot be checked due to the connection problem of the External Catalog, thereby solving the problem that some BI systems work with Doris. It can be infodb_support_ext_catalogcontrolled by the configuration item of FE. The default is that falsethe meta in the External Catalog is not returned information.)
