Implemented TLS 1.2 support with TLS/SSL client certificate authentication using smart card GIDS applet for client certificate storage and digital signing. See the documentation (uFR_Series_NFC_reader_API.pdf) for details.
Extended APDU implementation based on uFR Plus firmware version 5.0.57.
Inclusion for <unistd.h> for Linux variants has been fixed.
Timestamp server for Windows DLLs codesigning has been changed to http://timestamp.sectigo.com in csign.cmd.
Copyright range of years updated in src/ver_inf.rc.

Version 5.0.56 - NDEF functions update, minor bugs fixed. uFCoder.aar - minSdkVersion set to 21, targetSDK set to 29

Version 5.0.51 - NDEF bugs fixed - M24SR/NTAG4xx tags read/write NDEF records fixed, NDEF RAM Emulation Write fixed, Android NFC flags updated

NTAG 424 Tag Tamper support added.

version 5.0.42 - Linux MultiReader functions fixed, communication with uFR devices on Linux improved

ReaderOpen updated - removed search for uFR Online devices from the function due to multiple platform incompatibility, bad file descriptor error fixed, minor bugs fixed

Improved MRZ check-sum algorithm in MRTD_MRZSubjacentCheck() function (ICAO MRTD related).

RSA "off-card" hash signer patch implemented (for PKCS#11 module with PIN request)

New functions implemented:
   UFR_STATUS SetISO14443_4_Mode_GetATS();
   UFR_STATUS SetISO14443_4_Mode_GetATSM();
   Used to select ISO14443-4 tag and get its ATS, UID and SAK
