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
　* Add Corsican language support. Update several translations.
　* Update documentation

- Windows:
　* Officially, the minimum supported version is now <strong>Windows 10</strong>. VeraCrypt may still run on Windows 7 and Windows 8/8.1, but no active tests are done on these platforms.
　* EFI Bootloader:
　　* Fix bug in PasswordTimeout value handling that caused it to be limited to 255 seconds.
　　* Rescue Disk: enhance "Boot Original Windows Loader" by using embedded backup of original Windows loader if it is missing from disk
　　* Addition of Blake2s and removal of RIPEMD160 & GOST89
　* Enable memory protection by default. Add option under Performance/Driver Configuration to disable it if needed.
　　* Memory protection blocks non-admin processes from reading VeraCrypt memory
　　* It may block Screen Readers (Accessibility support) from reading VeraCrypt UI, in which case it can be disabled
　　* It can be disabled by setting registry value "VeraCryptEnableMemoryProtection" to 0 under "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\veracrypt"
　* Add process mitigation policy to prevent VeraCrypt from being injected by other processes
　* Fix Secure Desktop issues under Windows 11 22H2
　* Implement support for mounting partially encrypted system partitions.
　* Fix false positive detection of new device insertion when Clear Encryption Keys option is enable (System Encryption case only)
　* Better implementation of Fast Create when creating file containers that uses UAC to request required privilege if not already held
　* Allow choosing Fast Create in Format Wizard UI when creating file containers
　* Fix formatting issues during volume creation on some machines.
　* Fix stall issue caused by Quick Format of large file containers
　* Add dropdown menu to Mount button to allow mounting without using the cache.
　* Possible workaround for logarithmic slowdown for Encrypt-In-Place on large volumes.
