Changed behavior
| Changelog entry | Changed behavior |
|---|---|
| 25090 | Previous Behavior Default Setting: TLS certificate validation was deactivated by default for external file connections (HTTPS, FTPS) in IMPORT and EXPORT queries. Action Required: Users had to manually activate certificate validation via database parameters (-etlCheckCertsDefault=1) or SQL syntax (VERIFY CERTIFICATE) to secure connections. New Behavior Default Setting: TLS certificate validation is now activated by default for external file connections like HTTPS and FTPS across all IMPORT and EXPORT queries. Action Required: Users had to manually deactivate certificate validation via database parameters (-etlCheckCertsDefault=0) or SQL syntax (IGNORE CERTIFICATE). Error Handling: Connections without valid TLS certificates will fail with errors such as: SSL certificate problem: unable to get local issuer certificate Public Key Priority: Providing a public key via SQL syntax (PUBLIC KEY 'sha256//<key>') will override other certificate validation settings and enable explicit validation. |
| 24938 | The database port check will now be done when starting a database (db_start) and not when creating (db_create) or configuring (db_configure) a database. |
| 24714 | 1. Several packages were updated 1. Java 17 is the new default Java version for Java UDFs 2. New Script-Options-Parser for Java UDF's |
| 20854 | Regular expression library was upgraded from PCRE to PCRE2 10.44., so there might be changed behavior. For details refer to documentation on the PCRE2 syntax: http://pcre.org/current/doc/html/pcre2syntax.html and PCRE syntax: http://pcre.org/original/doc/html/pcresyntax.html. |
