Contributions
Decompilation engine

- siriak: Code cleanup (#1363)
Improvements & Bugfixes
- Added option to display all members, including compiler-generated members and getters/setters in tree view. (#747)
- Added option to display metadata token in 10-based or hex format. (#628)
- Reorganized option pages. (#1130)
- Local functions: Code is no longer hidden if local functions are used in the code, as long as they're not decompled correctly. Note that this might still lead to compile errors, if anonymous types or lambdas are used in the local functions.
- Decompilation of invalid IL
- Improved decompilation of C++/CLI constructs
- Improved stability of analyzers
- Various smaller bugfixes
Misc
- CreateCecilObjectModel: extension method to help plugin writers porting their plugins to ILSpy 4.0
- IAmbience API revived: If you want to nicely print type names or member signatures in C# style, you can now use CSharpAmbience
- "Open containing folder" and "Open command line here" added to Assembly tree nodes.
- Experimental PDBgen (no lambda support, no yield/async state machines; very basic C#)
- New IAnalyzer API
- Added IDocumentationProvider: allows providing XML doc comments from custom sources
- Added IDebugInfoProvider: allows providing debug info (variable names and sequence points)
Architectural Changes
For ILSpy 4 we replaced Mono.Cecil with System.Reflection.Metadata. The wiki entry on SRM deals at length with information that is important to addin writers, the background story and some of the performance/memory improvements you as a user of ILSpy can expect.
Our goal for this version given the underlying architectual changes is as follows: "As good or better as ILSpy 3.2 in terms of decompilation quality, stability, performance and memory usage."
ILSpy 4.0 RC2
Only bug fixes in comparison to RC1. Prior feature release notes apply.

ILSpy 4.0 Alpha 1
Technical details for this first release of ILSpy 4.0 are available in a dedicated page in our wiki: SRM deals at length with information that is important to addin writers, the background story and some of the performance/memory improvements you as a user of ILSpy can expect.
Our goal for this version given the underlying architectual changes is as follows: "As good or better as ILSpy 3.2 in terms of decompilation quality, stability, performance and memory usage."
Therefore we ask you to compare the last released production version with this Alpha 1 - we are confident that even at this early stage we match the quality in decompilation. If not, please do open an issue (sample assemblies very much appreciated!)
ILSpy 3.2
Security Advisory
Resource Deserialization Security Vulnerability If you are using an older version, please update immediately! (especially if the assemblies you decompile are untrustworthy). Note that the integration in Visual Studio via Roslyn is not affected.
The Visual Studio addin is now available on the marketplace, the Decompiler engine as usual via NuGet.
