Added support for implement type options - it is now possible to define whether code-fix/refactoring generated properties should be auto- or throwing-properties and at which place in the class should newly generated members be inserted. They can be set via OmniSharp configuration, such as omnisharp.json file. (PR: #1672)
```
{
    "ImplementTypeOptions": {
        "PropertyGenerationBehavior": "PreferAutoProperties", // or "PreferThrowingProperties" which is the default
        "InsertionBehavior": "AtTheEnd" // or "WithOtherMembersOfTheSameKind" which is default
    }
}
```
Added support for organizing usings on format. This can be set via OmniSharp configuration, such as omnisharp.json file. (PR: #1686)
```
{
    "FormattingOptions": {
        "OrganizeImports": true
    }

[1.34.0] - 2019-07-15

Added support for Roslyn code actions that normally need UI - they used to be explicitly sipped by OmniSharp, now it surfaces them with predefined defaults instead. (#1220, PR: #1406) These are:
- extract interface
- generate constructor
- generate overrides
- generate Equals and GetHashCode
Improved analyzers performance by introducing background analysis support (#1507)
According to official Microsoft .NET Core support policy, .NET Core 1.0 and 1.1 (project.json-based .NET Core flavors) have reached end of life and went out of support on 27 June 2019. OmniSharp features to support that, which have been obsolete and disabled by default since version 1.32.2 (2018-08-07), are now completely removed.
Fixed a bug where some internal services didn't respect the disabling of a project system (#1543)
Improved the MSBuild selection logic. The standalone instance inside OmniSharp is now preferred over VS2017, with VS2019 given the highest priority. This ensures that .NET Core 3.0 works correctly. It is also possible manually provide an MSBuild path using OmniSharp configuration, which is then always selected. (#1541, PR: #1545)
```
    {
        "MSBuild": {
            "MSBuildOverride": {
                "MSBuildPath": "C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Enterprise\\MSBuild\\15.0\\Bin",

            }
        }
    }
```

[1.33.0] - 2019-07-01

Added support for .editorconfig files to control formatting settings, analyzers, coding styles and naming conventions. The feature is currently opt-into and needs to be enabled using OmniSharp configuration (#31, PR: #1526)
```
    {
        "FormattingOptions": {
            "EnableEditorConfigSupport": true
        }
    }
```
Analyzers improvements (PR: #1440)
- Dynamically loaded / modifiable rulesets instead without full restart on omnisharp after every change
- Reanalyze updated projects
- Built-int Roslyn diagnostics can be controlled by rulesets even when analyzers are not enabled
- Faster analysis since project isn't updated every time
- When project is restored it is re-analyzed with correct dependencies
Added support for various renaming options - renaming any symbol can now propagate to comments or strings, and renaming a method symbol can also rename its overloads. They can be set via OmniSharp configuration, such as omnisharp.json file (they are disabled by default). (PR: #1495)
```
{
    "RenameOptions": {
        "RenameInComments": true,
        "RenameOverloads": true,
        "RenameInStrings": true
    }

[1.32.2] - 2018-08-07

OmniSharp now targets net461, instead of net46 (PR: #1237)
Added new /codestructure endpoint which serves a replacement for the /currentfilemembersastree endpoint. The new endpoint has a cleaner design, properly supports all C# types and members, and supports more information, such as accessibility, static vs. instance, etc. (PRs: #1211 #1217)
Fixed a bug where language services for newly created CSX files were not provided if no CSX files existed at the moment OmniSharp was started (#1199, PR: #1210)
The legacy project.json support is now disabled by default, allowing OmniSharp to start up a bit faster for common scenarios. If you wish to enable project.json support, add the following setting to your omnisharp.json file. (PR: #1194)
```
{
    "dotnet": {
        "enabled": false
    }
}
```

[1.31.1] - 2018-05-28

Fixed bug where diagnostics from loaded .cake files was shown in the current file. (PR: #1201)

[1.31.0] - 2018-05-29

Update to Roslyn 2.8.0 packages, adding support for C# 7.3. (PR: #1182)
MSBuild project system no longer stops when a project fails to load. (PR: #1181)
Fixed null-reference exception that could be thrown during MSBuild discovery. (#1188, PR: #1189)
Fixed an issue where referenced projects outside of OmniSharp's target path/solution would not be evaluated properly if they were multi-targeted (e.g. contained <TargetFrameworks>), which could result in downstream failures. (omnisharp-vscode#2295, PR: #1195)
Removed logic that set MSBuildSDKsPath environment variable before loading a project. This environment variable overrides normal MSBuild SDK resolution, which breaks resolution for custom MSBuild SDKs (for more information on MSBuild SDKs, see the documentation). (#1190, PR: #1192)
- Breaking Change: Removing this logic means that OmniSharp will no longer load .NET Core projects that target a .NET Core SDK with a version <= 1.0.3 by default. If you need to restore this behavior, you can set the following option in an omnisharp.json configuration file:
```
{
    "MSBuild": {
        "UseLegacySdkResolver": true
    }
}
```
  See Configuration Options for more details on omnisharp.json.
Support /rename endpoint in .cake files.
Support custom .rsp files in scripting. It is now possible to use omnisharp.json to define a path to an .rsp file, containing predefined namespaces and assembly references, and OmniSharp will respect those as part of its language services for CSX files. For example, given the following .rsp file:
```
/r:bin/FakeLib.dll
/r:bin/FSharp.Core.dll
/r:bin/FSharpx.Extras.dll
/u:Fake
/u:FSharpx
/u:System.Linq
/u:System.IO
```
and the following omnisharp.json:
```
{
    "Script": {
        "RspFilePath": "path/to/my.rsp"
    }
}
```
OmniSharp will automatically include the predefined DLLs and namespaces in the language services for all the scripts in the given folder (in case of a local omnisharp.json) or on the machine (in case of a global omnisharp.json). Note that the reference to mscorlib/System.Runtime is always there anyway and doesn't need to be specified again in the .rsp file. (#1024, PR: #1112)
- Note that the reference to mscorlib/System.Runtime is always there anyway and doesn't need to be specified again in the .rsp file
- only imports and references are supported as part of the .rsp file (scripting doesn't support other compiler settings passed using the .rsp file). In the future, depending on whether the feature is available in Roslyn, OmniSharp may also support defining a scripting globals type via .rsp file.
.cake files are now parsed using the C# version Latest rather than Default, to match the runtime behavior of Cake. (PR: #1201)
Updated DotNetTest result to include messages from stdout and stderr. (PR: #1203)

[1.30.1] - 2018-05-11

[1.23.2] - 2017-08-14

[1.23.1] - 2017-08-08

Fixed two regressions with MSBuild projects:
1. .NET Core projects were not properly processed if Mono was installed.
2. When Mono is installed, don't set MSBuildExtensionsPath to $mono_prefix/xbuild unless both $mono_prefix/msbuild and $mono_prefix/xbuild/15.0 also exist.
Properly set new language version values to support C# 7.1.

[1.23.0] - 2017-08-07

Windows builds that run on Desktop CLR.
- omnisharp-win-x86.zip
- omnisharp-win-x64.zip
A *Nix build that be run on Mono 5.2.0 or greater. (Note that the --assembly-loader=strict flag must be specified when launch this build with Mono).
- omnisharp-mono.tar.gz
Standalone builds for OSX and Linux that include the Mono bits necessary to run OmniSharp.
- omnisharp-osx.tar.gz
- omnisharp-linux-x86.tar.gz
