Changed behavior
| Changelog entry | Changed behavior |
|---|---|
| 24031 | Lua modules lua-cjson (library cjson) and LuaExpat (library lxp) are updated: lua-cjson: 2.1.0 → 2.1.0.10, luaexpat: 1.3.0 → 1.5.2 |
| 23806 | Release 9.2.0 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/9.2.0/standard-EXASOL-all |
| 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. |
| 23470 | We updated the time zone database to version 2025a. The new version changed the definition of some time zones. Some historic time zone conversions now give different results, for example CET prior to May 1892. |
| 21564 | EXA_STATISTICS.EXA_DB_SIZE_DAILY and EXA_STATISTICS.EXA_DB_SIZE_HOURLY tables have for columns OBJECT_COUNT_AVG and OBJECT_COUNT_MAX changed data type from DECIMAL(6,0) to DECIMAL(9,0). EXA_STATISTICS.OBJECT_COUNT table has for column OBJECT_COUNT changed data type from DECIMAL(6,0) to DECIMAL(9,0). EXA_STATISTICS.EXA_DB_SIZE_DAILY and EXA_STATISTICS.EXA_DB_SIZE_HOURLY tables have for columns OBJECT_COUNT_AVG and OBJECT_COUNT_MAX changed data type from DECIMAL(6,0) to DECIMAL(9,0). EXA_STATISTICS.EXA_DB_SIZE_MONTHLY has for columns OBJECT_COUNT_AVG and OBJECT_COUNT_MAX changed data type from DECIMAL(6,0) to DECIMAL(9,0). |
| 19651 | Lua is updated from version 5.4.0 to version 5.4.7. LuaSocket module is updated from 3.0.rc1 to 3.1.0. LuaSec module is updated from 1.0.2 to 1.3.2. |
| 19629 | - IMDS v1 is now explicitly set for all new AWS native deployments that are created by c4. - The "c4 update cluster" command will now create a "LaunchTemplate" resource during the template update. This launch template resource is used to force IMDS v1 for all newly added nodes (e.g. added as a part of worker cluster creation). |
