 the interfaces are correct and ctypes structures match the platform.
 
+Release notes

+  - mbed TLS wrapper added
+  - Minor bug fixes
+
+01/25/2019
+  - Python JWT support
+  - Python configuration structures added
+  - Restructure of secure boot app
+
+01/04/2019
+  - Added GCM functions
+  - Split AES modes into separate files
+  - Bug fix in SWI START driver
+
+10/25/2018
+  - Added basic certificate functions to the python wrapper.
+  - Added Espressif ESP32 I2C driver.
+  - Made generic Atmel START drivers to support most MCUs in START.
+  - Added AES-CTR mode functions.
+  - Python wrapper functions now return single values with AtcaReference.
+  - Added mutex support to HAL and better support for freeRTOS.
+  
+08/17/2018
+  - Better support for multiple kit protocol devices
+
+07/25/2018
+  - Clean up python wrapper
+
+07/18/2018
+  - Added ATCA_NO_HEAP define to remove use of malloc/free.
+  - Moved PEM functions to their own file in atcacert.
+  - Added wake retry to accomodate power on self test delay.
+  - Added ca_cert_def member to atcacert_def_s so cert chains can be traversed
+    as a linked list.
+
+03/29/2018
+  - Added support for response polling by default, which will make commands
+    return faster (define ATCA_NO_POLL to use old delay method).
+  - Removed atcatls related files as they were of limited value.
+  - Test framework generates a prompt before locking test configuration.
+  - Test framework puts device to sleep between tests.
+  - Fixed mode parameter issue in atcah_gen_key_msg().
+  - ATECC608A health test error code added.
+
+01/15/2018
+  - Added AES-128 CBC implementation using AES command
+  - Added AES-128 CMAC implementation using AES command
+  
+11/22/2017
+  - Added support for FLEXCOM6 on SAMG55 driver
+  
+11/17/2017
+  - Added library support for the ATECC608A device
+  - Added support for Counter command
+  - atca_basic functions and tests now split into multiple files based on
+    command

+  - Updated atcab_ecdh_enc() to work more consistently
+
+07/01/2017
+  - Removed assumption of SN[0:1]=0123, SN[8]=EE. SN now needs to be passed in
+    for functions in atca_host and atca_basic functions will now read the
+    config zone for the SN if needed.
+  - Renamed atcab_gendig_host() to atcab_gendig() since it's not a host
+    function. Removed original atcab_gendig(), which had limited scope.
+  - Fixed atcah_hmac() for host side HMAC calculations. Added atcab_hmac().
+  - Removed unnecessary ATCADeviceType parameters from some atca_basic
+    functions.
+  - Added atcacert_create_csr() to create a signed CSR.
+  - New HAL implementation for Kit protocol over HID on Linux. Please see the

+    section in this file for more information.
+  - Added atcacert_write_cert() for writing certificates to the device.
+  - Added support for dynamic length certificate serial numbers in atcacert.
+  - Added atcab_write() for lower level write commands.

+  - Added atcab_verify() command for lower level verify commands.
+  - Added atcab_verify_stored() for verifying data with a stored public key.
+  - Removed atcab_write_bytes_slot(). Use atcab_write_bytes_zone() instead.
+  - Modified atcab_write_bytes_zone() and atcab_read_bytes_zone() to specify a
+    slot
+  - Added atcab_verify_validate() and atcab_verify_invalidate()
+  - Improvements to host functions to handle more cases.
+  - Added atcab_updateextra(), atcab_derive_key()
+  - Added support for more certificate formats.
+  - Added general purpose hardware SHA256 functions. See atcab_hw_sha2_256().
+  - Removed device specific config read/write. Generic now handles both.
+  - Removed unnecessary response parameter from lock commands.
+  - Enhanced and added unit tests.
+  - Encrypted read and write functions now handle keys with SlotConfig.NoMac
+    set
+  - atcab_cmp_config_zone() handles all devices now.

+      found
+    - currently implemented on SAMD21/R21 I2C, SAMV71
+    - additional discovery implementations to come
+  - TLS APIs solidified and documented
+  - Added missing doxygen documentation for some CryptoAuthLib methods 
+  - Stubs for HAL SPI removed as they are unused for SHA204A and ECC508A
+    support
+  - bug fixes
+  - updated atcab_sha() to accept a variable length message that is > 64 bytes
+    and not a multiple of 64 bytes (the SHA block size).
+  - refactored Cert I/O and Cert Data tests to be smaller
+  - 'uncrustify' source formatting
+  - published on GitHub
+
+9/19/2015
+  - Kit protocol over HID on Windows
+  - Kit protocol over CDC on Linux
+  - TLS integration with ATECC508A

+  - Added ca_cert_def member to atcacert_def_s so cert chains can be traversed
+    as a linked list.
+
+03/29/2018
+  - Added support for response polling by default, which will make commands
+    return faster (define ATCA_NO_POLL to use old delay method).
+  - Removed atcatls related files as they were of limited value.
+  - Test framework generates a prompt before locking test configuration.
+  - Test framework puts device to sleep between tests.
+  - Fixed mode parameter issue in atcah_gen_key_msg().
+  - ATECC608A health test error code added.
+
+01/15/2018
+  - Added AES-128 CBC implementation using AES command
+  - Added AES-128 CMAC implementation using AES command
+  
+11/22/2017
+  - Added support for FLEXCOM6 on SAMG55 driver
+  
+11/17/2017
+  - Added library support for the ATECC608A device
+  - Added support for Counter command
+  - atca_basic functions and tests now split into multiple files based on
+    command
+  - Added support for multiple base64 encoding rules
+  - Added support for JSON Web Tokens (jwt)
+  - Fixed atcab_write_enc() function to encrypt the data even when the device
+    is unlocked
+  - Fixed atcab_base64encode_() for the extra newline
+  - Updated atcab_ecdh_enc() to work more consistently
+
+07/01/2017
+  - Removed assumption of SN[0:1]=0123, SN[8]=EE. SN now needs to be passed in
+    for functions in atca_host and atca_basic functions will now read the
+    config zone for the SN if needed.
+  - Renamed atcab_gendig_host() to atcab_gendig() since it's not a host
+    function. Removed original atcab_gendig(), which had limited scope.
+  - Fixed atcah_hmac() for host side HMAC calculations. Added atcab_hmac().
+  - Removed unnecessary ATCADeviceType parameters from some atca_basic
+    functions.
+  - Added atcacert_create_csr() to create a signed CSR.
+  - New HAL implementation for Kit protocol over HID on Linux. Please see the
+    Incorporating CryptoAuthLib in a Linux project using USB HID devices
+    section in this file for more information.
+  - Added atcacert_write_cert() for writing certificates to the device.
+  - Added support for dynamic length certificate serial numbers in atcacert.
+  - Added atcab_write() for lower level write commands.
+  - Fixed atcah_write_auth_mac(), which had wrong OpCode.
+  - Added atcab_verify() command for lower level verify commands.
+  - Added atcab_verify_stored() for verifying data with a stored public key.
+  - Removed atcab_write_bytes_slot(). Use atcab_write_bytes_zone() instead.

+  - Added atcab_updateextra(), atcab_derive_key()
+  - Added support for more certificate formats.
+  - Added general purpose hardware SHA256 functions. See atcab_hw_sha2_256().
+  - Removed device specific config read/write. Generic now handles both.
+  - Removed unnecessary response parameter from lock commands.
+  - Enhanced and added unit tests.
+  - Encrypted read and write functions now handle keys with SlotConfig.NoMac
+    set
+  - atcab_cmp_config_zone() handles all devices now.

+Description: Python Wrapper Library for Microchip Security Products
+ # Python CryptoAuthLib module
+ .
+ ## Introduction
+ This module provides a thin python ctypes layer to evaluate the cryptoauthlib
+ interface to Microchip CryptoAuthentication devices.
+ .
+ ### Code Examples
+ Code examples for python are available on github as part of
+ [CryptoAuthTools](https://github.com/MicrochipTech/cryptoauthtools)
+ under the [python/examples](https://github.com/MicrochipTech/cryptoauthtools/tree/master/python/examples)
+ directory
+ .
+ .
+ ## Installation
+ ### CryptoAuthLib python module can be installed through Python's pip tool:
+ ```
+     pip install cryptoauthlib
+ ```
+ .
+ ### To upgrade your installation when new releases are made:
