• Sys.setenv() since R 2.7.0 was limited to 1023 characters for the name+value, and silently truncated the value otherwise. It should now work up to the Windows limit (which is version-dependent).

2.2.1 UNCATEGORIZED (Windows)

• Input from the Rgui console was changing the letter 255 (ÿ in Latin-2) in the character set to letter 1.

• Sys.setenv() and Sys.getenv() now use the Windows API functions rather than the buggy C runtime functions, allowing longer settings, e.g. for a long PATH.

• Sys.setenv() and Sys.getenv() now use the Windows API functions rather than the buggy C runtime functions, allowing longer settings, e.g. for a long PATH.

• dir() does a better job when dir is of rhe form "d:", the currrent directory is not the root on that drive, and either 'full' or 'recursive' is true.

• Sys.setenv() and Sys.getenv() now use the Windows API functions rather than the buggy C runtime functions, allowing longer settings, e.g. for a long PATH.

• getwd() could segfault (PR#13424).

• The attenmpt to make the 'Load' button in the GUI preferences start in the home directory failed if the latter was specified with forwward slashes, and reset the current search directory for other file open dialogs (e.g. for opening a script).

• Rcmd INSTALL has a new option --pkglock to allow a per-package lock directory (useful for parallel installs).

• R_HOME/bin/helpPRINT.bat now contains an example of use with MiKTeX to produce a PDF version of the help file.

2.8.0 patched BUG FIXES (Windows)

• The windows() device now works around the total clipping of semi-transparent rectangles and circles that extend outside the device region.

• The script editor did not respect user preferences for the background colour.

• normalizePath() no longer returns a garbage string when the input is bad; it now signals an error. (PR#13199)

• File share/sh/dcf.sh was not distributed with the binary build. (PR#13200)

• dir.create() did not print the path correctly in warning messages.

• The C-level function consolecmd had been broken in non-Latin-1 single-byte locales in R 2.8.0 by changes intended to support the Japanese IME. This affected some menu items in Rgui (e.g. to source R files with non-Latin-1 names) and submitting commands from the script editor, but only in rarer encodings such as Central European, Greek and Cyrillic. (PR#13195, probably also PR#13120)

• The attenpt to make the 'Load' button in the GUI preferences start in the home directory failed if the latter was specified with forwward slashes, and reset the current search directory for other file open dialogs (e.g. for opening a script).

• The installer would sometimes write the current version information to the registry even if that option was not checked.

• Rcmd INSTALL --with-package-versions now works in a few more cases (of lazy loading and lazy data), but still many of the options are not supported (e.g. --use-zip). Versioned installs are now deprecated, so regard them as unsupported on Windows (and a warning is given). (PR#13284)
