For other readers:
The R-devel NEWS is a good source to find possible change reasons:

And if you want to follow along, you can get it as an RSS feed from

Hi,
I have a failing unit test in my package tryCatchLog on the CRAN build
infrastructure
(https://cran.r-project.org/web/checks/check_results_tryCatchLog.html)
with "R Under development (unstable) (2019-09-27 r77229)"
and the unit tests just ensures consistent behaviour of R (not of my package)
as a precondition:
The failing unit test is caused by
typeof(getOption("warn"))
[1] "integer"
but it should be
[1] "double"
This is related to this bug fix:
CHANGES IN R 3.6.1 patched BUG FIXES
‘options(warn=1e11)’ is an error now, instead of later leading to C
stack overflow because of infinite recursion.
which occurred in rev 77226. It explicitly coerces the warn value to
integer.
I have no build infrastructure for dev and want to find out if this is caused by
- my mistake
- changes in the R dev version
- the new C compilers used (correlates with the failing unit test)
It is changes in the dev and patched versions, and also your mistake:
your test shouldn't be so stringent. The docs don't say that the value
has to be a double; in fact, they suggest it should be a whole number
value (talking about 0, 1, "2 or more", not about what would happen with
options(warn = pi/2), for example.
In older versions, options(warn = pi/2) is treated the same as
options(warn = 1), and in the new version, it is displayed as 1 as well.

Can somebody (having the R dev version available) please help me and answer the
result of
typeof(getOption("warn"))
using "R Under development (unstable) (2019-09-27 r77229)" or newer?
Thanks a lot and sorry for the "noise"!
Jurgen
PS: These R (dev) versions did work as expected (returning "double") but were
also using older C compilers:
- R Under development (unstable) (2019-09-20 r77199)
- R Under development (unstable) (2019-09-22 r77202)
- R Under development (unstable) (2019-09-25 r77217)
- R version 3.6.1 Patched (2019-09-25 r77224)
- R version 3.6.1 (2019-07-05)
- R version 3.6.0 beta (2019-04-15 r76395)
- R version 3.5.3 (2019-03-11)
- R version 3.5.2 (2018-12-20)
