3.1.2

Fixed

• Fixed parsing of the nwb_version attribute which followed the previous suggestion to have a NWB- prefix.
  @t-b #2118
• Fixed a performance regression introduced in pynwb 2.8.0 that affected reading NWB files with a large
  number of objects or fields of objects. @rly #2121
• Fixed load_type_config, unload_type_config, and get_loaded_type_config acting on a copy of the global type map
  instead of the global type map itself. @rly #2121

Changed

• Added an argument copy to get_type_map to control whether a copy of the type map is returned or not.
  If copy=False, the returned type map will be a direct reference to the global type map. @rly
  #2121
• Deprecated calling get_type_map with the extensions argument. Call load_namespaces on the returned TypeMap
  instead. @rly #2121
