drewnoakes/metadata-extractor 2.9.0

v2.9.0

on GitHub

This release contains fixes across the entire project uncovered during the creation of the official .NET port of this project. This new implementation was originally ported from Java to C# by Yakov Danilov (for Imazen LLC). Since then it's been heavily refactored. Going forward, it will be kept functionally equivalent to the Java implementation.
