Hi,

R's software development life cycle is documented here:

  https://www.r-project.org/doc/R-SDLC.pdf<https://www.r-project.org/doc/R-SDLC.pdf>

This is available via the Certification link, under Documentation, on the main R Project web page:

  https://www.r-project.org<https://www.r-project.org>

Section 4.4 of the document, on page 10, covers the release cycles, and section 4.6, on page 11, covers maintenance, support and retirement.

Section 4.6 includes the following text at the end of that section on page 12:

"The x.y.0 releases are maintained via a series of x.y.z patch releases. At a new x.y.0 version of R, the prior version is retired from formal support. R Core’s efforts are then focused on the new Release (and the on-going Development) version. No further development, bug fixes or patches are made available for the retired versions. Thus there is always only one current version of R. However, the SVN repository will allow older release branches to be reopened, should the need arise."


Version 4.0.0 of R was released on April 24, 2020, thus ending formal support for version 3.x.x, with the last 3.x.x version being 3.6.3, which was released on February 29, 2020.

Regards,

Marc Schwartz
