Time for a new crisp feature on elmah.io. All software applications have a version number (or at least should have). Being able to distinguish one version from the other is important. That's why we have implemented version number support on elmah.io.

Basically, there's a new version property on the message details:

The idea here is that you set this version number to the current version number of your application through appSettings, assembly version or similar.

Having a version number on all messages, lets you do funky searches like this:

To add a version number on all of the messages logged to elmah.io, add the following code somewhere during initialization:

Elmah.ErrorLog.GetDefault(null); // Forces creation of logger client
var logger = ErrorLog.Client;
logger.OnMessage += (sender, args) =>
{
    args.Message.Version = "1.2.3"; // Requires elmah.io.core version >= 2.0.26
}

I addition to setting the version number through the OnMessage event, there are alternatives as well as support for logging frameworks like log4net, NLog and Serilog. Check out the Adding Version Information article on our documentation site for more details.
