1.16.0

[DennisDyallo]

Release date: March 31st, 2026

Features:

• The FIDO2 application now supports SCP03 and SCP11 secure channels over USB CCID on YubiKeys with firmware version 5.8 and above. This enables encrypted communication with the FIDO2 application, matching the SCP support already available for PIV, OATH, OTP, and YubiHSM Auth. (#428)

• ZLib compression and decompression support has been added via a new ZlibStream class. The PivSession.KeyPairs property now correctly handles compressed certificate formats. (#417)

Bug Fixes:

• The MSVC C runtime is now statically linked in Yubico.NativeShims, removing the dependency on the Visual C++ Redistributable. Additionally, cmake_minimum_required has been bumped to 3.15 for proper CMP0091 policy support, and an explicit exit /b 0 has been added to prevent findstr exit codes from leaking into the build process. (#427)

Documentation:

• NFC requirements and SCP usage examples have been added to the Fido2Session documentation. (#428)

• Comments and logical grouping have been added to the NativeShims CMakeLists and readme. (#427)

Miscellaneous:

• The Serilog dependency has been removed from integration tests and the sandbox app, simplifying the test project dependencies.

Dependencies:

• Several dependencies across the Yubico.Core, Yubico.YubiKey, and GitHub Actions workflows have been updated to newer versions. (#424, #429, #430, #432, #433, #435, #436, #437, #438)
