Changed behavior

Changelog entry Changed behavior
23747 - The default image for all new deployments is `ubuntu/images/hvm-ssd/ubuntu-focal-20.04-amd64-server-20250210` - The newly added nodes (e.g. worker cluster nodes) now use the default image of the current c4 binary installed on the nodes. In case the user has set CCC_AWS_IMAGE_NAME, c4 will use that image instead.
23373 Release 9.1.0 of the Script-Languages-Container was integrated, which also provides package dependency updates. Changed packages of SLC can be found at: https://github.com/exasol/script-languages-release/tree/master/doc/changes/package_diffs/9.1.0/standard-EXASOL-all
22864 The UDF client binary name in the standard container has been renamed exaudfclient_py3 → exaudfclient Release 9.0.0 of the Script-Languages-Container was integrated, which also provides security related updates of several packages. Changed packages of SLC can be found at: https://github.com/exasol/script-languages-release/tree/master/doc/changes/package_diffs/9.0.0/standard-EXASOL-all
22457 The c4 parameter CCC_GROUND_PROC_FILES_OPEN is no longer available.
15363 Exasol ODBC driver and Client SDK drivers are checking the provided connection string more rigorously now. As a result, in particular, IMPORT/EXPORT FROM/TO EXA from a 'jdbc:exa:<something>` won't be possible anymore (it shouldn't have ever worked).
