After "Patch applied successfully" I get the following exception;

Unable to apply delta updates, falling back to full update.: System.Exception: Invalid release entry: 903B6727BF05FA7B1F46C78066DAA37FFE72926E Caiman IQ Desktop.deps.json.shasum 117288

at Velopack.UpdateManager.DownloadUpdatesAsync(UpdateInfo updates, Action`1 progress, Boolean ignoreDeltas, CancellationToken cancelToken)

The issue appears to be that entryRegex format doesnt like that:

As an example, this fails:

Regex entryRegex = new Regex(@"^([0-9a-fA-F]{40})\s+(\S+)\s+(\d+)[\r]*$");
var m = entryRegex.Match("903B6727BF05FA7B1F46C78066DAA37FFE72926E Caiman IQ Desktop.deps.json.shasum 117288");

Whereas this passes and on the following group test:
var m = entryRegex.Match("903B6727BF05FA7B1F46C78066DAA37FFE72926E CaimanIQDesktop.deps.json.shasum 117288");

I would offer to fix this but this regex isnt compatible with my brain...
