Phil, Yes, you're right. For some reason it was missing in the documentation. I've removed it from the release message.

David,

Thanks for the release!

The release message in Github [https://github.com/polyml/polyml/releases/tag/v5.8.1] says "Added Weak.touch. Including this in code that uses a weak reference ensures that the reference will not be garbage-collected." I think Weak.touch was actually introduced in Poly/ML 5.6 (or even 5.5.3).? It looks like 5.8.1 just changes its implementation.

After the recent bug fixes I thought it was time to produce a new release.? There are very few new features; it's almost all bug fixes.

Thanks to everyone for the patches and bug reports.

David

Rather soon, I will continue on the Isabelle repository with Poly/ML repository versions, because I want to start using the experimental GCPercent feature. (The next Isabelle release will probably be in Jan-2021.)

I've updated the GCPercent branch to incorporate 5.8.1.

For everyone else: the GCPercent branch adds information to the statistics about operations, primarily garbage-collection, that may cause ML to be unresponsive for significant amounts of time. It requires a separate process to read the statistics since obviously the local ML code can't. It's rather experimental at the moment which is why it's not yet in the main line.
