What's better than Fable 5?
Fable 5.1 and 5.2! π (And yes, I totally forgot to announce 5.1).
Both releases bring plenty of fixes across various targets. Check out the release notes for details:

Introducing Claude Fable 5: a Mythos-class model that weβve made safe for general use.
Its capabilities exceed those of any model weβve ever made generally available.
There is a new test framework joining the F# ecosystem: Scriptorium.
It is designed from the ground up as a cross-target testing framework, seamlessly supporting both F# .NET and Fable compilation targets (JavaScript only at the time of writing)

π Fable 5.0.0-alpha.14 is out!
This one has a big focus on Python and adding support for Nullness to Fable (both your project and dependencies needs to be written with nullness in mind for it to work)
To benefit from all the new features you need to use Fable.Core beta too
1/
The goal of this alpha is for people to be able to experiment with Nullness in Fable and see how it plays out both in term of usage and for creating bindings.
