Unfortunately, I won't be able to use a lot of the improvements in my projects, since it'll take some time for everyone to adopt it. But maps and dirty schedulers (!!!) are both very welcome.
Do heed the warning in the README wrt dirty schedulers...
Note that the functionality is experimental, and not
supported. This functionality will be subject to backward
incompatible changes. You should not enable the dirty
scheduler functionality on production systems. It is only
provided for testing.
