&h1(RMR Release Notes)
The following is a list of release highlights for the core RMR library and 
wrappers which are housed in the same repository.
These are extracted directly from the CHANGES_*.txt files at the repo root; 
please refer to those files for a completely up to date listing of
API changes (as generated documents may lag).  
&space

The RMR repo houses two distinct release entities: the core RMR package
and the python wrapper package.
To avoid naming conflicts (tags mostly) The core package uses odd 
major version numbers (e.g. 3.2.1) and the wrapper package uses even
major version numbers. 
The release notes are split into two sections; please be sure to 
scroll to the section that is appropriate.
