• added support for backslashes in the PLC paths
• improved parsing of PLC paths
• improved testing

LogixDriver

• added support for writing structures using dicts
• added get_tag_info method for looking up data type and other information about a tags
• added new data_type_name for all tag definitions
  • makes filtering lists simpler due to differences between struct and atomic tags
• fixed bit writes >.31 for LINTs
• fixed some issues with writing boolean arrays longer than 32 elements
• fixed issues when duplicate tags are in the same read/write call
  • especially with duplicate bit level writes having unexpected results
• improved packet size estimation

SLCDriver

• fixed bit level writing in SLCDriver

• mypy support added @EduardoHi

LogixDriver

• added array support for non-string data types for the data_format in generic_message
  • e.g. data_format=[('example', 'SINT[5]'), ]
• added string (2-byte len) and logix_string (4-byte len) support for data_format in generic_message
• improved error messages for bad tag names, fix ambiguous 'Invalid tag request - 'plc_tag' error message

SLCDriver

• added get_file_directory
  • confirmed working for SLC and MLX1100, other MLX models will require help from someone with the hardware to debug against
• added r/w support for L/ST/A files

• fixed error with get_module_info method

• generic_message method now accepts bytes or ints for service, class, instance, and attribute arguments
• minor refactoring and exception improvements

• (new) - SLCDriver for SLC 500 and MicroLogix
  • read/write methods similar to LogixDriver

• fixed loggers so they all contain the module name, not just the class name

• removed autologging dependency
• changed minimum Python version to 3.6.1 due to bug w/ NamedTuples
• some internal restructure and refactoring
• improved some exception handling and raising
• multi-request read/write calls now only filter RequestError and DataError, other exceptions will have to be handled by the user

• restructured some modules, there is now a CIPDriver class that LogixDriver inherits from
  • CIPDriver handles session registrations, forward open/close, generic_message, etc
  • possibly to be used as a base for a SLC/Micrologix driver
• fixed issue with improper unpacking of session ID that would sometime cause a crash
• set minimum Python version to 3.6.1
  • 3.6 had a bug with overloading methods in NamedTuple that broke checking validity of Tag objects
• [Breaking Change] list_identity method now returns a dict with the full identity object, not just a string of the product name

• replaced the generic_read/generic_write method with a single generic_message method
  • it should now work properly, the previous methods did not always
  • replaced some internal methods to use generic_message instead of manually building the requests
  • tested getting/setting drive parameters from a PF525
• updated documentation
• lots of internal changes and restructuring

• minor refactoring
• fix for not using instance ids in requests for array tags
