Hello,

I would like to announce the release of tpm2-openssl 1.3.1-rc0: https://github.com/tpm2-software/tpm2-openssl/releases/tag/1.3.1-rc0

This is a bugfix release:
 - Fixed compatibility with OpenSSL 4.0.
 - Fixed the ECDSA signature algorithm to omit the parameters field (thanks to @smhmeier).
 - Fixed cipher padding validation according to PKCS#5/PKCS#7, so zero padding is now rejected (thanks to @hyperfinitism).
 - Fixed buffer indexing for block ciphers without padding (thanks to @hyperfinitism).
 - Fixed cleansing of sensitive data upon buffer deallocation and fixed buffer allocator consistency (thanks to @hyperfinitism).
 - Fixed missing NULL checks and harmless type cast errors in RSA and ECDSA algorithms (thanks to @hyperfinitism).
 - Fixed semaphore destruction (thanks to @Deadolus).


Kind Regards,
Petr
