Changes between 1.25.9 and 1.26.6 (21 September 2023) :

- All OSes:
　* Security: Ensure that XTS primary key is different from the secondary key when creating volumes
　　* Issue unlikely to happen thanks to random generator properties but this check must be added to prevent attacks
　　* Reference: CCSS,NSA comment at page 3: https://csrc.nist.gov/csrc/media/Projects/crypto-publication-review-project/documents/initial-comments/sp800-38e-initial-public-comments-2021.pdf
　* Remove TrueCrypt Mode support. Version 1.25.9 can be used to mount or convert TrueCrypt volumes.
　* Complete removal of RIPEMD160 and GOST89 algorithms. Legacy volumes using any of them cannot be mounted by VeraCrypt anymore.
　* Add support for BLAKE2s as new PRF algorithm for both system encryption and standard volumes.
　* Introducing support for EMV banking smart cards as keyfiles for non-system volumes.
　　* No need for a separate PKCS#11 module configuration.
　　* Card PIN isn't required.
　　* Generates secure keyfile content from unique, encoded data present on the banking card.
　　* Supports all EMV standard-compliant banking cards.
　　* Can be enabled in settings (go to Settings->Security Tokens).
　　* Developed by a team of students from the Institut national des sciences appliquées de Rennes.
　　* More details about the team and the project are available at https://projets-info.insa-rennes.fr/projets/2022/VeraCrypt/index_en.html.
　* When overwriting an existing file container during volume creation, add its current size to the available free space
