 # 8.3.8xx (Habu series release 14)
 * [VISUALIZER] Fix off-by-one error in markup for the very last line of the file
 * [BUGFIX] -- Fake API fix for ZipFile, MethodPoint, SingleVisit, SourceLink to enable their activation
-* [BUGFIX] -- `--dependency` and `/p:AltCoverDependencyList` -- work around the behaviour of `dotnet test` with an argument ending `.dll` or `.exe`, directly through API and in docs for direct use.
-* Make explicit dependencies through `--dependency` have priority over other assembly resolution; this allows explicit specification of GAC'd assemblies to be found by .net core AltCover builds in place of the .net core stubs (works around Mono.Cecil issue #863).
-* Add a `--verbose`option for AltCover, the converse of `-q`.  Away from the command line, adds meaning to the `Verbosity` option value `System.Diagnostics.TraceLevel.Verbose`.  Currently `Verbose` output shows more of the selection of files for instrumentation, noting when files are excluded from the process.

+* [BUGFIX] -- Issue #156: Make explicit dependencies through `--dependency` have priority over other assembly resolution.  This works around a Mono.Cecil misfeature (Mono.Cecil issue #863) where the `netstandard2.0` Cecil binaries do not consider the GAC for Framework system assemblies, but instead will find stubs in `dotnet/shared/Microsoft.NETCore.App` for e.g. WPF related assemblies
+* [BUGFIX] -- Improve selection of non-embedded symbol files (between location in assembly debug header, the same directory as the assembly and any `--symbolDirectory` values) to avoid symbol mismatch when there are multiple possible files on offer
+* Add a `--verbose`option for AltCover, the converse of `-q`.  Away from the command line, adds meaning to the `Verbosity` option value `System.Diagnostics.TraceLevel.Verbose`.  Currently `Verbose` output shows more of the selection of files for instrumentation, noting when files are excluded from the process, symbol file selection etc.
 * Add a matching field, `ILoggingOptions.Verbose`, to the API as a sink to capture verbose output.
 * Other minor build process asjustments for SDK 6.0.300/F# 6.0.4 and later
