### Changes after audit

PropellerHeads applied fixes after receiving the audit report. Trail of Bits then audited the fixes; the findings are in the reports linked above.

PropellerHeads kept developing Turbine while Trail of Bits reviewed the code. Trail of Bits has not audited some newer parts. PropellerHeads consults an internal security consultant on all significant changes. A formal audit of post-review changes will follow.
