Ghidra 11.3 is out! There's some awesome new features, but I want to highlight how responsive the dev team is to questions, issues, and feature suggestions. They've addressed several issues I've opened, notably a bunch of quality of life UI/UX things I've had while using Ghidra.

Want to run roadrecon, but a device compliance policy is getting in your way? You can use the Intune Company Portal client ID, which is a hardcoded and undocumented exclusion in CA for device compliance. It has user_impersonation rights on the AAD Graph 😃
