Changed behavior
| Changelog entry | Changed behavior |
|---|---|
| 31226 | Release 11.2.0 of the Script-Languages-Container was integrated, which provides security related updates of several Ubuntu and PyPi packages. |
| 31127 | Database startup can now be blocked by the EXAStorage metadata overlap check. |
| 30131 | For the DUMP function, the size of its VARCHAR return type increased by five characters. Only the data type changed, the returned values remain unchanged. |
| 21012 | Fix introduces a minor change to JSON messages send from DB to VS adapter. SELECTs to Virtual Schemas created prior to Fix Versions could fail with error mentioning "org.glassfish.json.JsonObjectBuilderImpl$JsonObjectImpl.getBoolean". To avoid these errors, either run ALTER SCHEMA REFRESH after DB update or prior to update install a Virtual Schema JAR based on "virtual-schema-common-java" 14.0.5 or newer. E.g., for PostgreSQL Virtual Schema it's release 4.0.2 and respectively file "virtual-schema-dist-14.0.5-postgresql-4.0.2.jar". |
