I've used MariaDB in production a few years back and didn't notice any differences in operation except for an esoteric bug with some version of Ubuntu that required making a minor change to the config file...otherwise, it worked as a drop-in replacement as advertised, though this app didn't do anything particularly exotic outside of the standard Rails/ActiveRecord conventions...
Has much changed? Is MariaDB still pretty much a drop-in replacement? And has anyone moved a non-trivial app from MySQL to MariaDB...or would be confident in making that move on RDS, on the heels of this announcement? I mean, if there aren't any production problems, the change in licensing [1] alone seems like it could be enough of a reason (although I may be misunderstanding MySQL's licensing, it's always been a little confusing to me).

yes, MariaDB is still a drop-in replacement for MySQL with a number of enhancements. There are a few minor incompatibilities to be aware of.

We moved from MySQL on RDS to MariaDB and back and didn't run into any real issues.
Just to clarify here:
The license for MySQL remains the same (GPLv2). It has not changed at any point.
Apparently this doesn't include the version that comes with data at rest encryption (10.1.3):

RDS MariaDB already supports encryption at rest, so you don't need to wait for 10.1: http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Overvi...
MariaDB 10.1 is not a GA release, yet. When it goes GA, presumably this will also be available on RDS. Currently 5.5 & 10.0 are GA releases.
