The new version of OCaml, OCaml 4.11.0, has started its bugfix period: the set of new features is now mostly frozen, and in the three upcoming months, we will focus mostly on fixing bugs.
For this release cycle, we will experiment releasing an alpha version of the compiler.
This new alpha version is expected to work as a synchronization point for people working on updating the opam ecosystem for the new release. Once the opam ecosystem is in shape for some wider audience testings, we will publish a beta version as usual. This should be happen around June.
One of the most notable change in this release is
Statmemprof, a new statistical memory profiler directly integrated into the GC.
The provisional Changes list is here.
At this point of time, it is better to take this list with a grain of salt: there are a handful of new features that are still under integration, problematic features might be removed, and of course the list of bug fixes is incomplete.
But one of the most notable feature in this change log,
Statmemprof which a new statistical memory profiler API, is most probably here to stay.
