-## Install .Net Core 2.x Linux Dependencies

-The `./config.sh` will check .Net Core 2.x dependencies during agent configuration.  
 You might see something like this which indicate a dependency's missing.
 ```bash
 ./config.sh
     libunwind.so.8 => not found
     libunwind-x86_64.so.8 => not found
-Dependencies is missing for Dotnet Core 2.1
+Dependencies is missing for Dotnet Core 3.0
-Execute ./bin/installdependencies.sh to install any missing Dotnet Core 2.1 dependencies.
+Execute ./bin/installdependencies.sh to install any missing Dotnet Core 3.0 dependencies.
 ```
 You can easily correct the problem by executing `./bin/installdependencies.sh`.  
 The `installdependencies.sh` script should install all required dependencies on all supported Linux versions   
 > Note: The `installdependencies.sh` script will try to use the default package management mechanism on your Linux flavor (ex. `yum`/`apt-get`/`apt`). You might need to deal with error coming from the package management mechanism related to your setup, like [#1353](https://github.com/Microsoft/vsts-agent/issues/1353)

 ## Features
-  - Set Default shell to powershell for windows runners (#135)
+  - Added the "severity" keyword to allow action authors to set the default severity for problem matchers (#203)
-  - Use Powershell as fallback if Powershell Core is not available for default shell on windows (#142)
 
 ## Bugs
-  - Removed unintended additional fields on error and warning commands (#137)
+  - Fixed generated self-hosted runner names to never go over 80 characters (helps Windows customers) (#193)
+  - Fixed `PrepareActions_DownloadActionFromGraph` test by pointing to an active Actions repository (#205)
 
 ## Misc
-  - N/A
+  - Updated the publish and download artifact actions to use the v2 endpoint (#188)
