# 2023 Changelog
|

### ClickHouse release v23.2.6.34-stable (570190045b0) FIXME as compared to v23.2.5.46-stable (b50faecbb12)

|
#### Improvement
|
||
|
|
* Backported in [#48709](https://github.com/ClickHouse/ClickHouse/issues/48709): Formatter '%M' in function formatDateTime() now prints the month name instead of the minutes. This makes the behavior consistent with MySQL. The previous behavior can be restored using setting "formatdatetime_parsedatetime_m_is_month_name = 0". [#47246](https://github.com/ClickHouse/ClickHouse/pull/47246) ([Robert Schulze](https://github.com/rschu1ze)).
