[1.0.0-BETA4] - 2020-02-05

The main changes on the user side are the fact that R functions are Clojure functions, and the initial suppoort for a Renjin backend. Details below:

• performance improvement: using an R environment rather than an R list for session memory
• some refactoring to allow other kinds of R backends, in particular exending the Session protocol to take care of details such as printing and package in spection
• more careful id management of sessions
• checking the object class on creation of R objects
• being careful when printing objects of lost sessions
• R objects now extend the IFn inerface, so that R functions are Clojure functions
• bugfix in regreshing objects across sessions
• simplified the implementation of require-r -- functions can now be handled as regular objects
• handling of strange symbols/keywords: refactored a bit, added some filtering
• initial support of a Renjin (pure-JVM R) backend
• handling failures in require-r
• changes in logging

[1.0.0-BETA3] - 2020-01-28

• handling unhandled cases in java->naive-clj conversion
• loading data, not only functions, at require-r
• require-r optimization: all underlying robjects are created once, then bound to namespaces
• more careful handling of data conversion of list names: names with reader special characters are not converted to keywords

[1.0.0-BETA2] - 2020-01-21

• added '$ as binary operator
• performance bugfix: using native double array and type hint when conferting integer R vectors with missing values to clj
• recognizing reticulate python functions as functions
• bugfix in overriding default session args

[1.0.0-BETA1] - 2020-01-07

Initial v1 version.

Main developments since earlier versions:

• code generation
• changes in error handling, printing, etc.
• requiring of R packages inspired by the python interop story (though less sophisticated)
• function call syntax a bit different (no detailed function signatures yet)
• documentation and tests using notespace

[0.0.1-SNAPSHOT] - Sep. 2019 - Dec. 2019

Initial draft version
