# Pike Series Release Notes¶

## 3.30.2¶

### Bug Fixes¶

• The JSONFormatter formatter now converts unserializable objects with repr() to prevent JSON serialization errors on logging. The fix requires oslo.serialization 2.20.2 or newer. (Bug #1593641)

## 3.27.0¶

### New Features¶

• If the log format string includes %(error_summary)s, it will be replaced with a summary of the current error when there is one and with “-” when there is no error. If the log format string does not include %(error_summary)s the error summary will be appended to the end of the line automatically, only if there is an error.

## 3.24.0¶

### New Features¶

• Systemd native journal support is added. You can enable this in services with the use_journal flag.

## 3.21.0¶

### New Features¶

• A new oslo_log.log.is_debug_enabled helper function is added that allows to determine whether debug mode is enabled for logging.
