 - The [PivSession.ChangeManagementKey](xref:Yubico.YubiKey.Piv.PivSession.ChangeManagementKey(Yubico.YubiKey.Piv.PivTouchPolicy)) method was incorrectly assuming Triple-DES was the default management key algorithm for FIPS keys. The SDK now verifies the management key alorithm based on key type and firmware version. ([#162](https://github.com/Yubico/Yubico.NET.SDK/pull/162))
 - The SDK now correctly sets the IYubiKeyDeviceInfo property [IsSkySeries](xref:Yubico.YubiKey.IYubiKeyDeviceInfo.IsSkySeries) to True for YubiKey Security Key Series Enterprise Edition keys. ([#158](https://github.com/Yubico/Yubico.NET.SDK/pull/158))
-- Exceptions are now caught when running [PivSession.Dispose](xref:Yubico.YubiKey.Piv.PivSession.Dispose). This fixes an issue where the Dispose method could not close the Connection in the event of a disconnected YubiKey. ([#104](https://github.com/Yubico/Yubico.NET.SDK/issues/104))

 - A dynamic DLL resolution based on process architecture (x86/x64) has been implemented for NativeShims.dll. This fixes a reported issue with the NativeShims.dll location for 32-bit processes. ([#154](https://github.com/Yubico/Yubico.NET.SDK/pull/154))
