   1  This files describes API changes in /backup/*,
   2  information provided here is intended especially for developers.
   3  
   4  === 3.1 ===
   5  
   6  * New close() method added to loggers so they can close any open resource. Previously
   7    any backup and restore operation using the file logger may be leaving unclosed files.
   8  * New destroy() method added to loggers, normally called from backup and restore controllers
   9    own destroy() method to ensure that all references in the chained loggers are deleted
  10    and any open resource within them is closed properly.
  11  
  12  === 3.0 ===
  13  
  14  * The backup_auto_keep setting, in automated backups configuration, is now
  15    renamed to backup_auto_max_kept as part of a rationalise of naming (see MDL-50602)
  16  
  17  === 2.6 ===
  18  
  19  * The backup_controller_dbops::create_temptable_from_real_table()
  20    method is not available anymore. Temp tables must be created
  21    inline always.
  22  
  23  * Using the info field from backup_ids_temp or backup_files_temp
  24    must now go via backup_controller_dbops::decode_backup_temp_info() and
  25    backup_controller_dbops::encode_backup_temp_info(). The implementation
  26    of the encoding has changed.  These new functions encapsulate any future
  27    changes to the encoding.
  28  
  29  === 2.5 ===
  30  
  31  * New optional param $sortby in backup set_source_table() allows to
  32      specify the ORDER BY clause to be used. Previously it was required
  33      to use the set_source_sql() more complex alternative in places
  34      requiring ordering.
  35  * The old 1.9 files backuplib.php, lib.php and restorelib.php and the bb directory,
  36      (all under /backup) have been deleted and no code should rely on them anymore.
  37  
  38  === 2.4 ===
  39  
  40  * Since 2.3.1+ the backup file name schema has changed. The ID of the course will always be part of
  41      the filename regardless of the setting 'backup_shortname'. See MDL-33812.
  42  
  43  === 2.3 ===
  44  
  45  * Since 2.3.1+ the backup file name schema has changed. The ID of the course will always be part of
  46      the filename regardless of the setting 'backup_shortname'. See MDL-33812.
  47  
  48  === 2.2 ===
  49  
  50  * Since 2.2.4+ the backup file name schema has changed. The ID of the course will always be part of
  51      the filename regardless of the setting 'backup_shortname'. See MDL-33812.
