Imageoptim taking much longer with Middleman > 4.3

[umerebryx]

Normally my build used to take 3-4 mins to complete. After upgrading to middleman 4.3 and middleman-imageoptim (0.3.0) build process is now taking 45-50 mins.

Even the skipped images are taking longer. Is there a way to ignore imageoptim during middleman build process? Or any suggestions how I can get this back to 3-4 mins.

Environment:

Middleman 4.3.5
middleman-imageoptim (0.3.0)
Ubuntu 16.04
Ruby 2.5.3
builder 1.7.3

I'm experiencing this as well on a mac 10.13.6

middleman 4.3.5
middleman-imageoptim (0.3.0)
ruby 2.6.0

I was just looking at this and it looks like something has changed about how the updated_images list is built in Middleman::Imageoptim::Optimizer.

With middleman 3.3.12 and middleman-imageoptim 0.2.1 that list is only images that have been created/updated during the current build and I don't see any [skipped] lines in the build output.

With middleman 4.x and middleman-imageoptim 0.3.0 that list contains every single image in the entire build directory, whether or not it was created/updated, and I see a [skipped] line in the build output for every image.

In the little bit of digging I've done so far I haven't spotted anything obvious in this gem that has changed.

It has something to do with changes in the ManifestResource that is causing the manifest file to be overwritten in the first stage of the build, so then in the second stage we don't have any information about which files have been optimized, so we have to do them all again.

The digging continues...

#63 takes one of my projects from being a 22 minute build down to 2 minutes.
