Dear list,

We are about one year behind current R (Sagemath Cloud even installed a 
"modern" R Jupyter kernel as an alternative to "our" R for Jupyter 
purposes). To solve this, three patches need your attention :

Sage-7.6.beta4 + Trac#20523 <https://trac.sagemath.org/ticket/20523> 
(upgrade R to 3.3.2) + Trac#21767 <https://trac.sagemath.org/ticket/21767> 
(add curl as new standard package) + Trac#21770 
<https://trac.sagemath.org/ticket/21770> (add pcre as new standard package) 
passes ptestlong with two transient errors :
----------------------------------------------------------------------
sage -t --long src/sage/homology/simplicial_set_morphism.py  # Bad exit: 2
sage -t --long src/sage/homology/simplicial_complex.py  # 1 doctest failed
----------------------------------------------------------------------
Both tests pass when run standalone.

Reminder : since Trac#22189 <https://trac.sagemath.org/ticket/22189>, we 
***depend*** on some SSL system-wide library, and we strongly recommend 
OpenSSL. This is true also for patchbots ;-).

This should close the R saga (for now) by allowing the current interfaces 
to work with R >= 3.3.x.
For docudrama lovers, the next cliffhanger should be a future Rpy2-based R 
interface ;-). But don't hold your breath...

HTH,
