We will upgrade the Ubuntu release on our servers from 22.04 LTS to 24.04 LTS. This will include newer version of many services. An overview of the most important version changes can be found below. For other services/packages, you can always use the Ubuntu Package Search. The distribution name for Ubuntu 24.04 LTS is "noble".
- PHP will be updated from 8.1 to 8.3
- PostgreSQL will be updated from 14 to 16.2
- MariaDB (MySQL) will be updated from 10.6.7 to 10.11.8
- Python will be updated from 3.10 to 3.12
Furthermore, many services (such as Apache2) are migrating their regex engine from PCRE to PCRE2. You can find a list of incompatibilities here.
