It has landed - the Beta of ILSpy 1.0: What's new / changed: a new BAML decompiler (the main reason for the wait since M3), Analyzer improvements, bug fixes.
We will focus mainly on bug fixes for the final version (new features will go into 2.0), therefore please test your scenarios and provide feedback so we can get the "gold" version in your hands as soon as possible. Feel free to do so either via our forums or file bug reports directly on GitHub.
