- In "install" target, create `${DESTDIR}` if needed.
- In **mkconcurrent**, extract and cache make target fragments directly from an installed build.\*.mk so we no longer need to maintain a copy of them in the script.
- [**build.lib.mk**](https://bsdbuild.hypertriton.com/man5/build.lib.mk): Disable use of Libtool by default. Generate .la files even when `USE_LIBTOOL=No`. Handle .dylib and .dll files directly.

Merge the "depend" from [**build.dep.mk**](https://bsdbuild.hypertriton.com/man5/build.dep.mk). Include support for cc65 compiler.
- [**mkconfigure**](https://bsdbuild.hypertriton.com/man1/mkconfigure): Make the generated `config.log` a runnable shell script containing all test code and compilation commands. This allows individual tests to be "replayed" easily by copy/pasting from `config.log` to a shell.
- [**mkconfigure**](https://bsdbuild.hypertriton.com/man1/mkconfigure): Show influential environment variables in generated "--help" output. Introduce `Register_env_var()` directive. Use `$IFS` instead of sed for path traversals. Add test for `$PATH_SEPARATOR`. Use expr to validate `--with-*` and `--enable-*` arguments. Honor `${EXECSUFFIX}` in `$PATH` searches. Don't invoke config.guess unnecessarily if --build is provided.
- [**mkconfigure**](https://bsdbuild.hypertriton.com/man1/mkconfigure): Now exports `LDFLAGS` to `Makefile.config`.
- Don't output Lua definitions unless `--output-lua` is passed to [**mkconfigure**](https://bsdbuild.hypertriton.com/man1/mkconfigure).
- **cc**: Define `HAVE_CC_GCC` and `HAVE_CC_CLANG`.
- **libidn**: Check for `idn2` instead of the old `idna` interface.
- **png**: Use `libpng-config --static --libs` to include any libpng dependencies in `${PNG_LIBS}`.
- **pthreads**: Add subtests `HAVE_PTHREAD_{MUTEX,COND,}_T_POINTER` to determine whether `pthread_mutex_t`, `pthread_cond_t` and `pthread_t` are pointer types or not. Needed for `_Pure_Attribute_If_Unthreaded` in agar.
- **x11**: Honor `--x-includes=*` and `--x-libraries=*` configure arguments. If XKB is not found then fallback to libXf86misc.

- [**mkconfigure**](https://bsdbuild.hypertriton.com/man1/mkconfigure): In `MkExecOutput()` and `MkExecOutputPfx()`, always initialize `MK_EXEC_FOUND` to `No`.
- [**mkconfigure**](https://bsdbuild.hypertriton.com/man1/mkconfigure): New Core functions `MkLog()`, `MkPrintSN()`, `MkComment()`, `MkCache()`, `MkCleanup()`, `MkLogCode()`, `MkRun()`.

- [**build.www.mk**](https://bsdbuild.hypertriton.com/man5/build.www.mk): Multi-lingual document targets are now specified as `${HTML}` elements with the .html.var extension (as opposed to .html). Write charset variants into `${CHARSETS}` directory.
- **cc**, **cxx**, **objc**: When cross-compiling, autodetect `${host}-cc` et al.
- **opengl**: On MacOS X, prefer "-framework OpenGL" to -lGL where available.
- **sdl**: On MacOS X, fallback to trying `-framework SDL` if **sdl-config** fails.

- **jpeg**: Remove `_WIN32` exception (there are workarounds the `<windows.h>` issue).
- **perl**: Fix compiler warnings in test (due to myPerl -> my\_perl).

## [3.0] - 2012-08-10

### Added

- [**mkconfigure**](https://bsdbuild.hypertriton.com/man1/mkconfigure): New directives `MAPPEND()`, `CHECK_PERL_MODULE()`, `DEFAULT_DIR()`. Introduced new configure options `--moduledir`, `--statedir` and `--libexecdir` (and others for autoconf compatibility).

### Changed

- It is now possible to control conditional compilation from configure (i.e., a Makefile's `${SRCS}` definition may safely reference configure-defined variables). In separate builds, the mkconcurrent script is now invoked at the very end of configure, and it now performs more extensive parsing of Makefiles as well.
- Prevent redundant Makefile.config definitions from being produced.
- [**mkconfigure**](https://bsdbuild.hypertriton.com/man1/mkconfigure): Allow use of terminating backslash to escape long line breaks in input scripts.
