| 1 | 4.2.3 | 2023/03/17 |
| CHANGES IN R 4.2.3 C-LEVEL FACILITIES The definition of DL_FUNC in ‘R_ext/Rdynload.h’ has been changed to be fully C-compliant. This means that functions loaded via for example R_GetCCallable need to be cast to an appropriate type if they have any arguments. .Machine has a new element sizeof.time_t to identify old systems with a 32-bit type and hence a limited range of date-times (and limited support for dates millions of years from present). PACKAGE INSTALLATION (Windows) The default C++ standard had accidentally been left at C++11 when it was changed to C++14 on Unix. BUG FIXES As "POSIXlt" objects may be “partially filled” and their list components meant to be recycled, length() now is the length of the longest component. as.POSIXlt.Date() could underflow for dates in the far past (more than half a million years BCE).

| 2 | 4.2.2 | 2022/11/04 |
| CHANGES IN R 4.2.2 NEW FEATURES tools::Rdiff(useDiff = TRUE) checks for the presence of an external diff command and switches to useDiff = FALSE if none is found. This allows R CMD Rdiff to always work. On Windows, environment variable R_LIBCURL_SSL_REVOKE_BEST_EFFORT can be used to switch to only ‘best-effort’ SSL certificate revocation checks with the default "libcurl" download method. This reduces security, but may be needed for downloads to work with MITM proxies (PR#18379). (macOS) The run-time check for libraries from XQuartz for X11 and Tcl/Tk no longer uses otool from the Apple Developer Tools (PR#18400). The LaTeX style for producing the PDF manuals, ‘Rd.sty’, now loads the standard ‘amsmath’, ‘amsfonts’ and ‘amssymb’ packages for greater coverage of math commands in the Rd \eqn and \deqn macros.

| 3 | 4.2.1 | 2022/06/25 |
| CHANGES IN R 4.2.1 NEW FEATURES New function utils::findCRANmirror() to find out if a CRAN mirror has been selected, otherwise fallback to the main site. This behaves in the same way as tools::CRAN_package_db() and is intended for packages wishing to access CRAN for purposes other than installing packages. The need for this was shown by a day when the main CRAN website was offline and a dozen or so packages which had its URL hardcoded failed their checks. INSTALLATION on a UNIX-ALIKE The libraries searched for by --with-blas (without a value) now include BLIS (after OpenBLAS but before ATLAS). And on macOS, the Accelerate framework (after ATLAS). (This is patterned after the AX_BLAS macro from the Autoconf Archive.) The included LAPACK sources have been updated to 3.10.1. UTILITIES The (full path to) the command tidy to be used for (省略されました) | ||
| 4 | 4.2.0 | 2022/04/25 |
| CHANGES IN R 4.2.0 SIGNIFICANT USER-VISIBLE CHANGES The formula method of aggregate() now matches the generic in naming its first argument x (resolving PR#18299 by Thomas Soeiro). This means that calling aggregate() with a formula as a named first argument requires name formula in earlier versions of R and name x now, so portable code should not name the argument (code in many packages did). Calling && or || with either argument of length greater than one now gives a warning (which it is intended will become an error). Calling if() or while() with a condition of length greater than one gives an error rather than a warning. Consequently, environment variable _R_CHECK_LENGTH_1_CONDITION_ no longer has any effect. Windows users should consult the WINDOWS section below for some profound changes including Support for 32-bit builds has been dropped. (省略されました) | ||
| 5 | 4.1.3 | 2022/03/13 |
| CHANGES IN R 4.1.3 NEW FEATURES The default version of Bioconductor has been changed to 3.14. (This is used by setRepositories and the menus in GUIs.) UTILITIES R CMD check --as-cran has a workaround for a bug in versions of file up to at least 5.41 which mis-identify DBF files last changed in 2022 as executables. C-LEVEL FACILITIES The legacy S-compatibility macros SINGLE_* in ‘R_ext/Constants.h’ (included by ‘R.h’) are deprecated and will be removed in R 4.2.0. BUG FIXES Initialization of self-starting nls() models with initialization functions following the pre-R-4.1.0 API (without the ... argument) works again for now, with a deprecation warning. Fixed quoting of ~autodetect~ in Java setting defaults (省略されました) | ||
| 6 | 4.1.2 | 2021/11/04 |
| CHANGES IN R 4.1.2 C-LEVEL FACILITIES The workaround in headers ‘R.h’ and ‘Rmath.h’ (using namespace std;) for the Oracle Developer Studio compiler is no longer needed now C++11 is required so has been removed. A couple more usages of log() (which should have been std::log()) with an int argument are reported on Solaris. The undocumented limit of 4095 bytes on messages from the S-compatibility macros PROBLEM and MESSAGE is now documented and longer messages will be silently truncated rather than potentially causing segfaults. If the R_NO_SEGV_HANDLER environment variable is non-empty, the signal handler for SEGV/ILL/BUS signals (which offers recovery user interface) is not set. This allows more reliable debugging of crashes that involve the console. DEPRECATED AND DEFUNCT The legacy S-compatibility macros PROBLEM, MESSAGE, ERROR, WARN, WARNING, (省略されました) | ||
| 7 | 4.1.1 | 2021/08/12 |
| CHANGES IN R 4.1.1 NEW FEATURES require(pkg, quietly = TRUE) is quieter and in particular does not warn if the package is not found. DEPRECATED AND DEFUNCT Use of ftp:// URIs should be regarded as deprecated, with on-going support confined to method = "libcurl" and not routinely tested. (Nowadays no major browser supports them.) The non-default method = "internal" is deprecated for http:// and ftp:// URIs for both download.file and url. On Windows, method = "wininet" is deprecated for http://, https:// and ftp:// URIs for both download.file and url. (A warning is only given for ftp://.) For ftp:// URIs the default method is now "libcurl" if available (which it is on CRAN builds). method = "wininet" remains the default for http:// (省略されました) | ||
| 8 | 4.1.0 | 2021/05/19 |
| CHANGES IN R 4.1.0 FUTURE DIRECTIONS It is planned that the 4.1.x series will be the last to support 32-bit Windows, with production of binary packages for that series continuing until early 2023. SIGNIFICANT USER-VISIBLE CHANGES Data set esoph in package datasets now provides the correct numbers of controls; previously it had the numbers of cases added to these. (Reported by Alexander Fowler in PR#17964.) NEW FEATURES www.omegahat.net is no longer one of the repositories known by default to setRepositories(). (Nowadays it only provides source packages and is often unavailable.) Function package_dependencies() (in package tools) can now use different dependency types for direct and recursive dependencies. The checking of the size of tarball in R CMD check --as-cran <pkg> may be tweaked via the new environment variable (省略されました) | ||
| 9 | 4.0.5 | 2021/04/03 |
| CHANGES IN R 4.0.5 BUG FIXES The change to the internal table in R 4.0.4 for iswprint has been reverted: it contained some errors in printability of ‘East Asian’ characters. For packages using LazyData, R CMD build ignored the --resave-data option and the BuildResaveData field of the ‘DESCRIPTION’ file (in R versions 4.0.0 to 4.0.4). | ||
| 10 | 4.0.4 | 2021/02/16 |
| CHANGES IN R 4.0.4 NEW FEATURES File ‘share/texmf/tex/latex/jss.cls’ has been updated to work with LaTeX versions since Oct 2020. Unicode character width tables (as used by nchar(, type = "w")) have been updated to Unicode 12.1 by Brodie Gaslam (PR#17781), including many emoji. The internal table for iswprint (used on Windows, macOS and AIX) has been updated to include many recent Unicode characters. INSTALLATION on a UNIX-ALIKE If an external BLAS is specified by --with-blas=foo or via environment variable BLAS_LIBS is not found, this is now a configuration error. The previous behaviour was not clear from the documentation: it was to continue the search as if --with-blas=yes was specified. BUG FIXES all.equal(x,y) now “sees” the two different NAs in factors, thanks to Bill Dunlap and others in (省略されました) | ||
| 11 | 4.0.3 | 2020/10/12 |
| CHANGES IN R 4.0.3 NEW FEATURES On platforms using configure option --with-internal-tzcode, additional values "internal" and (on macOS only) "macOS" are accepted for the environment variable TZDIR. (See ?TZDIR.) On macOS, "macOS" is used by default if the system timezone database is a newer version than that in the R installation. When install.packages(type = "source") fails to find a package in a repository it mentions package versions which are excluded by their R version requirement and links to hints on why a package might not be found. The default value for options("timeout") can be set from enviromnent variable R_DEFAULT_INTERNET_TIMEOUT, still defaulting to 60 (seconds) if that is not set or invalid. This may be needed when child R processes are doing downloads, for example during the installation of source packages which download jars or other forms of data.
