The CHANGES file tends to be the place to look for stuff like this.
From an entry for 2.5.0:

  o  There is support in both Rgui and Rterm for object/file name
 completion via the TAB key using package rcompgen. This can
 be disabled by setting the environment variable
 R_COMPLETION=FALSE when starting R (e.g. in ~/.Renviron).
 (Words within quotes are interpreted as file names, others as
 R object names. Use library(rcompgen); ?rc.options for more
 details, including tuning the behaviour.)

Subscribe to one of the feeds listed on
http://developer.r-project.org/RSSfeeds.html if you want to hear about
these things as they are developed (and watch typos being corrected,
etc.), or just read through the "New features in this version: Windows
specific" on the CRAN download site.

Some other help (on startup options) is available if you run Rgui
--help, and more if you use the Help|Console menu item. But there is no
Rgui manual as such. If you want to write one, I'd suggest putting it
on the R Wiki, so you don't take on sole responsibility for maintaining
it.
