# Changes for 0.1.3 - 20240124

## Update

## bug

### Fixed an error where only the hash (number) value, not the name, was displayed after setting onode_name.
    * The original text and hash data type were incorrect, so the original text was not displayed.

### Fixed an error where the whatap-otel.service file was not recognized in Ubuntu 14 version.
    * Add /etc/systemd/system/whatap-otel.service file. (link /usr/lib/systemd/system/whatap-otel.service)

# Changes for 0.2.0 - 20240619

## Update

### Supports linux aarch64.  

### Add security.conf. 

* Use security.conf file instead of existing paramkey.txt. 
* Use the value of the paramkey key in security.conf. 
* The default value is changed to specify “WHATAP” instead of a random value. (If “WHATAP” is specified, decryption is possible without key input.)
   
### Change the normalization option settings for SQL statements. 

* Always activate the function to separate and normalize parameters in SQL statements. 
	* Always set the trace_sql_normalize_enabled option to true. 
* If you have already disabled the normalization option (normalization stop setting), activate the setting to normalize and display parameters separately. 
	* Enable the profile_sql_param_enabled option.
	* Normalized parameters are separately encrypted and collected. 
	* You can check the data by decrypting it with the paramkey of security.conf. 	

### Add error information collection in span events
	dded error content extraction from events. In general, error content is more often entered as an event rather than an attribute.
	* Added key designation option to find errors in event
		otel_events_exception_keys=exception.type
		otel_events_error_message_keys=exception.message
		otel_events_error_stack_keys=exception.stacktrace
		otel_events_error_esc_keys=exception.escaped

# Changes for 0.2.1 - 20241106


## bug

### Fixed the Queue data processing function to not stop. 

We have corrected an error in which queue processing stops when a panic occurs during statistical data collection, preventing further data processing. 
In this case, data cannot be processed and data accumulates in the queue to the limit, increasing memory and making it impossible to check the data on the screen. 

### Log cleanup 

Fixed an issue where unnecessary logs were output and the log file size increased.
