 Synapser is compatible with [reticulate](https://rstudio.github.io/reticulate/) and the two packages can be used together in the same R session.
 
-As a workaround, if you wish to communicate with Synapse in an R session that also uses reticulate, you can use the [Synapse Python client](https://python-docs.synapse.org/build/html/index.html) through reticulate.

+As of synapser v2.0.0, it is still only compatible with reticulate v1.28 due to a miscellaneous update in [reticulate v1.29](https://rstudio.github.io/reticulate/news/index.html#misc-1-29).  Specifically, `py_to_r()` now succeeds when converting subtypes of the built-in Python types (e.g. list, dict, str).  Please install reticulate v1.28.
