pkgbuild 1.4.8

• New Config/build/never-clean DESCRIPTION option to avoid adding
  --preclean to R CMD INSTALL (e.g., when header files have changed)
  (@krlmlr, #204).

• has_rtools() & co. now work correctly on aarch64 Windows, when
  RTOOLS45_AARCH64_HOME is not set (@remlapmot, #203).

• pkg_build() and pkgbuild_process now work corrently when building
  binary packages from non-standard file names (#208).

pkgbuild 1.4.7

• pkgbuild now supports R 4.5.x and Rtools45.

• has_build_tools() (and related functions) now do not explicitly check
  for Rtools on Windows and R 4.3.0 and later, but rather they try to
  compile a simple package, like on Unix, for #199.

pkgbuild 1.4.6

• No changes.

pkgbuild 1.4.5

• pkgbuild now does a better job at finding Rtools 4.3 and 4.4 if they
  were not installed from an installer.

• pkgbuild now detects Rtools correctly from the Windows registry
  again for Rtools 4.3 and 4.4

pkgbuild 1.4.4

• pkgbuild now supports R 4.4.x and Rtools44 (#183).

pkgbuild 1.4.3

• pkgbuild now does not need the crayon, rprojroot and prettyunits
  packages.

pkgbuild 1.4.2

• Running bootstrap.R now works with pkgbuild_process, so it also works
  from pak (r-lib/pak#508).

pkgbuild 1.4.1

• New Config/build/extra-sources DESCRIPTION option to make pkgbuild aware
  of extra source files to consider in needs_compile().

• New Config/build/bootstrap DESCRIPTION option. Set it to TRUE to run
  Rscript bootstrap.R in the package root prior to building the source
  package (#157, @paleolimbot).

• pkgbuild now supports Rtools43.

• pkgbuild now always appends its extra compiler flags to the ones that
  already exist in the system and/or user Makevars files (#156).

pkgbuild 1.4.0

• pkgbuild can now avoid copying large package directories when building a
  source package. See the PKG_BUILD_COPY_METHOD enviroment variable in
  ?build or the package README (#59).

  This is currently an experimental feature, and feedback is
  appreciated.

• R CMD build warnings can now be turned into errors, by setting the
  pkg.build_stop_for_warnings option to TRUE or by setting the
  PKG_BUILD_STOP_FOR_WARNINGS environment variable to true (#114).

• need_compile() now knows about Rust source code files, i.e. Cargo.toml
  and *.rs (#115).

• Now pkgbuild::build() will not clean up inst/doc by default if the
  Config/build/clean-inst-doc entry in DESCRIPTION is set to FALSE (#128).

• New PKG_BUILD_COLOR_DIAGNOSTICS environment variable to opt out from
  colored compiler output (#141).

• pkgbuild now works with a full XCode installation if the XCode Command
  Line Tools are not installed, on macOS, in RStudio (#103).

v1.3.1

• Accept Rtools40 for R 4.2, it works well, as long as the PATH includes
  both ${RTOOLS40_HOME}/usr/bin and ${RTOOLS40_HOME}/ucrt64/bin.
  E.g. ~/.Renviron should contain now

  PATH="${RTOOLS40_HOME}\usr\bin;${RTOOLS40_HOME}\ucrt64\bin;${PATH}"
  

  to make Rtools40 work with both R 4.2.x (devel currently) and R 4.1.x and
  R 4.0.x.
