MTE 1.4.1​

• Fixed some incorrect cipher/hash informational values.
• Fixed AES CBC mode issues on 32 bit platforms.
• Changed naming of Nuget packages to avoid conflicts when multiple packages are produced with different options.
• Fixed integer nonce conversion to byte arrays in C#, Go, Java, Python, and Swift to avoid potentially undefined behavior.

MTE 1.3.2​

• Fixed Swift MKE chunking buffer size issues.
• Fixed Java set entropy issue.
• Fixed documentation of C++ timestamp callback behavior.
• Fixed documentation of Objective-C timestamp callback behavior.
• Fixed documentation of Swift timestamp callback behavior.
• Clarified documentation in mte_dec.h regarding the status.
• Fixed C Support API's sequence window argument to be signed instead of unsigned.
• Added missing documentation about timestamp callback usage in C Support API.
• Removed unused status code.
• Added IncrReset helper struct to C++ language interface to help with testing.
• Fixed Go decoder messages skipped integer return type.
• Removed UTF-8 BOMs from demo and language interface files.
• Removed unnecessary Swift code.
• Removed unnecessary semicolons from Swift.
• Improved WASM/JS nonce handling to support 64 bit nonce integers instead of only 32.
• Changed the Base64 state save function signatures in the C Support API to return char * instead of void * for consistency in Base64 functions.
• Renamed mte_message_get_timestamp64 to mte_verifier_get_timestamp64 in the C APIs. Moved this to its own header mte_verifier_defs.h, which is now distributed instead of mte_message_defs.h, which included many typedefs not needed by SDK users.

MTE 1.3.1​

• Changed TypeScript const enum to non-const enum since they are exported.
• Updated WASM demos to use the non-const enums.
• Fixed buffer size issues in Swift non-Base64 encode/decode methods.
• Fixed Swift handling of zero-length entropy for fake DRBG.
• Fixed typo in mte_enc.h comments.

MTE 1.3.0​

• Fixed Java MteJail to work correctly with Android/iOS 64 bit simulators.
• Fixed memory sizing issues in MKE.
• Fixed alignment issues in MKE.
• Added FIPS 140-3 self-test capability to all DRBG, cipher, and hash algorithms.
• Added APIs to let users run the self-tests.
• Removed mte_mke_base (MteMkeBase in language interfaces), moving its functionality to mte_base (MteBase) to consolidate all information and FIPS 140-3 self-tests in one place, and not require MKE to do DRBG primitive self-tests.
• Fixed comments in encoder and decoder headers related to external DRBGs.
• Refactored SHA-1/256/512 implementations to support optimizations of DRBGs based on them.
• Optimized HASH-SHA1/256/512 DRBGs.
• Refactored SHA-512 length handling to get full 128 bit support.
• Optimized MKE's use of provided ciphers and hashes.

Notes:​

• The first three issues are important bug fixes for anyone using jailbreak or MKE add-ons.
• There is a new build-time option for enabling FIPS 140-3 compliance. It is currently turned off for all builds because it adds overhead and none of our clients have FIPS requirements.
• MteMkeBase no longer exists, as documented in the notes above - just use MteBase instead.
• The package names have changed a bit to try to include all possible information. In particular, "Release" is shorted to "R" and add-ons are now included in the name.
• Trial mode builds have been added for iOS and Android in the Eclypses build to support demo apps.

MTE 1.2.0​

• Optimized tokenization algorithms.
• Fixed JNI issues when DRBG errors occur.
