These release notes used to live on the mailing list at: https://listman.redhat.com/archives/mgmtconfig-list/ until Red Hat killed off this excellent service recently. I'm adding them all here for reference. Before 0.0.9 there were no release notes.

|
This is a very important (and huge) release and has some important
|
|
fixes that landed since 0.0.18, including:
|
|
|
|
* A huge re-write of the elastic etcd clustering code base
|
|
* A significant improvement in the type unification algorithm
|
|
* An important import/class scoping bug was discovered and fixed
|
|
* New mcl functions and resource improvements
|
|
|
|
And much more...
|
|
|
|
What comes next is just polish, new features and small bug fixes!

NEWS
|
|
|
|
* A giant etcd re-write was completed and merged. The elastic
|
|
clustering algorithm is not perfect, however it should suffice for most
|
|
use cases, and it's always possible to point mgmt at an external etcd
|
|
cluster if you don't understand the limitations of the automatic
|
|
clustering algorithm. The important part is that the core code is much
|
|
cleaner now, so hopefully races and bugs of ignorance are gone now. :)
|
|
|
|
* I found an unfortunate bug in the type unification algorithm that
|
|
severely impacted performance for some types of code bases. This is now
|
|
fixed, and I hope we should not experience problems again! Special
|
|
thanks to Sam for talking me through the problem and understanding the
|
|
space better! Woo \o/
|
|
|
|
* An important import/class scoping bug was fixed. Thanks to Nicolas
|
|
for the bug report. We also added tests for this too!
|
|
|
|
* Nicolas also added our first os detection function. os.is_debian and
|
|
os.is_redhat are now in core. Get your favourite os added today!
|
|
|
|
* The polymorphic len function can also check str length.
|
|
|
|
* The exec resource got a big cleanup. It also learned the interrupt
|
|
trait so that long running commands can be forcefully killed if need
|
|
be.
|
|
|
|
* A fancy new test infra for testing functions over time was added.
|
|
Anytime we want to check our individual FRP functions are working as
|
|
expected, this is an easy way to add a test. This way, if we ever find
|
|
a bug, we can drop in a test with the fix. This actually helped find a
|
|
very subtle bug in readfile that nobody had experienced yet!
|
|
|
|
* File res with state => exists but no content now performs as
|
|
expected.
|
|
|
|
* Improved send/recv, since it was neglected a bit. Hopefully it ends
|
|
up being a useful primitive.
|
|
|
|
* Added a new synchronization primitive that I'm called
|
|
SubscribedSignal. I found it very useful for building some of my code,
|
|
and I hope you'll find it useful too. I'd offer it upstream to the sync
|
|
package if Google didn't force their crappy CLA nonsense on everyone
|
|
who wanted to send a patch. :/ Death by 1000 paper cuts, I guess.
|
|
|
|
* Added a match function in the new regexp core package. Try it out and
|
|
add some more functions!
|
|
|
|
* Wouter has been testing mgmt and filling all sorts of useful bug
|
|
reports. We fixed at least one related to a report, and more are
|
|
planned for the next release. Wouter also sent in one cleanup patch to
|
|
remove some dead code. Welcome to the project!
|
|
|
|
* We're looking for help writing Amazon, Google, DigitalOcean, etc
|
|
resources if anyone is interested, reach out to us. Particularly if
|
|
there is support from those organizations as well.
|
|
|
|
* Many other bug fixes, changes, etc...
|
|
|
|
* See the git log for more NEWS, and for anything notable I left out!
|
|
|
|
BUGS
|
|
|
|
* There are a few known issues, in particular with some over eager
|
|
checking done in the Validate portion of two resources, that should
|
|
actually be runtime checks in CheckApply. As a result, if you intend to
|
|
change some state during the graph execution, the resource won't see
|
|
it. These should be very easy to fix if someone is interested in
|
|
writing the patch!
|
|
|
|
TALKS
