R39

• fixed several mysql_format buffer overflows
• fixed a bug where the OnQueryError callback wasn't called if no result callback was used
• new mysql_option type: LOG_TRUNCATE_DATA; controls whether MySQL data (that means queries and fetched result data) should be truncated (queries to 64 characters, result data to 1024 characters) in the log file or not (true by default)
• added example scripts into repository (can be found in folder example_scripts)

R38

• fixed a bug where the OnQueryError callback wasn't called
• fixed a bug where mysql_errno returned 0 (which means 'no errors') when connection handle was invalid
• fixed a bug where mysql_unprocessed_queries returned wrong values
• fixed a bug where the character set wasn't always applied when calling mysql_set_charset
• fixed a bug where the charset was applied after the execution of a query, even though mysql_set_charset was called before mysql_tquery
• fixed an incompatibility with YSI 4
• fixed a bug where an argument type mismatch error occured when using orm_addvar_string with a normal string
• fixed a bug where the tag check in orm_addvar_float was ignored
• cleaned up include
• improved error handling within the ORM system
• removed old macro cache_get_field
• added more log messages regarding the charset

R37

• fixed a critical bug where ORM callbacks crashed the server
• fixed a bug where internal connections to a database were never closed
• fixed a bug where the internal query counter wasn't correctly decreased

R36

• redesigned internal threading system: parallel queries (mysql_pquery) are now executed in no strict order and the performance has been increased
• added the natives cache_get_query_exec_time and cache_get_query_string to retrieve query performance information
• fixed a bug with mysql_close crashing/hanging the server up
• fixed a bug where mysql_set_charset only changed the charset on the main connection
• fixed a bug where fetched values were stored incorrect

R35

• code cleanup
• performance improvements
• improved and added some log messages
• callback and format parameters at mysql_tquery and mysql_pquery are optional now
• all cache natives which use the active cache (all cache_* natives but cache_delete, cache_set_active and cache_is_valid) are ignoring the connectionHandle parameter
• added native orm_delvar to delete already added variables from an ORM instance
• added new log type LOG_ALL which logs everything
• added native cache_is_valid to check whether the specified cache is valid
• added native mysql_pquery to send parallel queries
• added native mysql_option to toggle global MySQL options
• added native mysql_current_handle to retrieve the currently used handle in a result callback
• added optional parameter pool_size to native mysql_connect
• added connection pool (to be used with new pool_size parameter in mysql_connect and new native mysql_pquery)
• fixed a bug where mysql_escape_string didn't set the destination var to empty if the source variable was empty
• fixed a bug where the HTML logging logged every callback even if there wasn't any log message in it
• fixed a bug where the plugin entered an infinite loop while calling mysql_close with the wait parameter activated

R34

• fixed bug where orm_update generated wrong queries
• fixed bug where queries sometimes lost connection to a remote database
• added natives "orm_load" and "orm_save" for even easier data management
• added additional (optional) parameter "use_cache" for native "mysql_query" to determine if the cache will be used or not
• added native "mysql_unprocessed_queries" to retrieve the amount of unprocessed queries
• improved backward compatibility a bit

R33

• added ORM system
• improved Windows XP compatibility (proven to work now)
• added parameter values to debug native log messages
• improved y_inline compatiblity code
• "orm_select" and "orm_insert" support y_inline (use "orm_select_inline" and "orm_insert_inline")
• added Cache-tags to cache_set_active, cache_save and cache_delete
• added natives "cache_get_row_count" and "cache_get_field_count"
• added more safety checks
• speed improvements
• fixed bug where mysql_free_result wasn't called internally if callback processing was skipped
• improved thread safety
• improved HTML-logging, reduced file size
• code cleanup
• rewrote the whole (multi-)threading system, multi-threading works now only per-connection (every connection has their own thread)
• added native "mysql_query" for unthreaded queries
• native "mysql_reconnect" no longer returns true if connection was successful and false if not, use "mysql_errno" instead
• improved makefile, use "make" to create a dynamic and static version, "make dynamic" and "make static" are self-explaining
