• Thanks to @mikekap, Buck now supports 1.6-style vendoring for Go.

v2016.02.29.01

• An experimental autodeps command was added. This currently only works with Java: https://buckbuild.com/command/autodeps.html
• The message a user sees when an http cache error is encountered is now configurable: https://buckbuild.com/concept/buckconfig.html#cache.http_error_message_format
• genrule now supports the tests argument: https://buckbuild.com/rule/genrule.html
• python_binary and python_test now support the linker_flags argument which indicates any flags that should be applied to any links for the build rule. https://buckbuild.com/rule/python_binary.html, https://buckbuild.com/rule/python_test.html
• A massive performance win (200x on HFS+ and 20x on ext4) when crawling the filesystem for build files (common during commands like buck project or buck build //...) when using watchman. This may not be enabled by default for your project, however. See https://buckbuild.com/concept/buckconfig.html#project.build_file_search_method for more details.
• Thanks to @mikekap, test selectors now work for python_test when using buck test. https://buckbuild.com/command/test.html
• Thanks to @janicduplessis, buck fetch now properly works on Windows when downloading from a disk-based Maven repository.
• Buck will now use clang's colors when using the SuperConsole.
• python_test rules can now be run with buck run.
• Thanks to @mikekap, the library argument was added to go_test to automatically use the same values for srcs, package, and deps from the specified library. https://buckbuild.com/rule/go_test.html
• The disk cache of Buck is now structured differently and performs better as a result on some filesystems.
• The licenses argument was added to all build rules. With buck query, one could construct the licenses used by a binary. For example, in the Buck repository: buck query "labels('licenses', deps('buck'))"
• You can now use the $(location ) macro with prebuilt_cxx_library.
• Thanks to @mikekap, Buck now has CI for Windows (via Appveyor).
• Thanks to @mrkane27, Buck now supports authentication when fetching from Maven repositories. This is controlled by the [credentials] section of the buckconfig: https://buckbuild.com/concept/buckconfig.html#credentials

v2016.02.08.01

• platform_linker_flags are now supported on apple_binary: https://buckbuild.com/rule/apple_binary.html
• Fixed a bug where Buck is only using the hostname portion of cache.http_url for distributed caches.

• export_file was documented: https://buckbuild.com/rule/export_file.html
• The directory cache is now enabled by default. @bolinfest noticed that lots of folks who blog about Buck never setup the cache, which is a big speed improvement in itself. Buck now picks a sensible location (buck-out/cache) for the cache by default and enables the dir cache. See https://buckbuild.com/concept/buckconfig.html#cache for more details.
• A number of options were added to control the size of the Super Console that Buck outputs. See https://buckbuild.com/concept/buckconfig.html#ui for more details.

v2016.02.01.01

• buck project now removes unused IntelliJ project files when generating a new project
• A read_config function was added that can be called in build files in order to read a config from the .buckconfig settings. https://buckbuild.com/function/read_config.html
• Buck will now properly filter all resources for android_resource rules instead of only filtering drawables by DPI. See http://developer.android.com/guide/topics/resources/providing-resources.html for valid resource folders (which are now checked by Buck) and valid DPI qualifiers.
• x86_64 Android builds are now supported by Buck
• Fixed a bug that would cause buck to hang if you had a build file that didn't parse.

v2016.01.25.01

• buck publish now only publishes CLASSPATH entries intstead of all deps when publishing a JAR
• The .buckconfig docs have been revamped. You can now link directly to any setting, and the formatting has been changed to be consistent throughout: http://buckbuild.com/concept/buckconfig.html
• You can now set the packaging type for a python_binary via a rule parameter in addition to the global setting in .buckconfig. See package_style at https://buckbuild.com/rule/python_binary.html
• @DanielGrech fixed buck quickstart to generate a valid .hgignore file
• Buck can now enforce the Build Tools version used when compiling Android code. This can be used to avoid the build time regression of aapt in 23.0.2: https://buckbuild.com/concept/buckconfig.html#android.build_tools_version, https://code.google.com/p/android/issues/detail?id=198488
• Buck will no longer consider codesign identities which are marked as invalid when building apple_* rules.

v2016.01.18.01

• @mikekap fixed Buck parsing the verbosity from a command running with buck run
• buck root was added: https://buckbuild.com/command/root.html
• @mogers added the buildfile operator to buck query: https://buckbuild.com/command/query.html#buildfile
• @mikekap updated Buck to use the latest version of PEX: https://github.com/pantsbuild/pex/
• @davido fixed a number of bugs with cross-cell build targets
• @anorth fixed a bug that prevented Buck from running under Python 3.5
• @davido fixed a long shutdown time issue when parallel parsing is enabled

• Fixed a bug when compiling with clang for NDK builds (assembling would fail)
• @grumpyjames added support for groovy_library: https://buckbuild.com/rule/groovy_library.html
• Buck can now take an agentpath for the invocation of the ProGuard step. This allows profiling with tools like YourKit and Profiler, which can be useful when trying to determine which optimizations you want to enable for your project. See https://buckbuild.com/concept/buckconfig.html#tools for more details.
• buck publish now checks to make sure a library you are publishing doesn't package a library that another library will also package and publish.

v2015.12.28.01

• Logs from apple_test and java_test tests are now reported after the tests have ran.
• Fixed a bug where Buck was not copying WatchKit stub .ipa which is required for the App Store when submitting a WatchOS 2 app.
• Fixed a bug where Buck would copy Frameworks into Frameworks.
• Improve watchman interaction performance by using Unix domain sockets.
• python.native_link_strategy was added to dictate how native dependencies are linked. See https://buckbuild.com/concept/buckconfig.html#python for more details.
• Buck now properly reports the failure of installation on an iOS device.

v2015.12.14.01

• An issue causing buck publish to not work was fixed by @davido on GitHub.
• Buck now reports the target that failed when buck project fails.
• Buck can now parse build files in parallel if you pass --config project.parallel_parsing=true on the command line. We expect to make this the default soon, but for now it is considered experimental. https://buckbuild.com/concept/buckconfig.html#project
• @LegNeato on GitHub added support for setting read and write HTTP headers when Buck talks to the HTTP cache. https://buckbuild.com/concept/buckconfig.html#cache

v2015.11.30.01

• Added a new type of caching which should improve cache hits of native code.
• test_rule_timeout_ms was added for python_test.
• Various reliability fixes to how Buck communicates over Nailgun
• Reduced Buck's memory usage.

v2015.11.23.01

• Buck now uses a Python version of nailgun so it no longer builds or runs native code in order to use buckd.
• When running a java_binary, the produced jar would not pass JVM arguments to the child process that actually runs your code. This is now fixed.
• buck test had a flag, --ignore-failing-dependencies, which is now a no-op.
• The soname field of cxx_library is now documented and has added functionality to add a version-aware macro to the field. See https://buckbuild.com/rule/cxx_library.html
• An issue where large source files were used in a cxx_library caused a Buck crash due to our use of MappedByteBuffers was fixed.
• Docs were added for platform_srcs and platform_compiler_flags for apple_* rules.
• Mike Kaplinskiy (@mikekap) added support for setting go.root in a repository: https://buckbuild.com/concept/buckconfig.html#go
• Mike Kaplinskiy (@mikekap) added support to run Buck under pypy.
• Buck now uses the new parser again as performance is the same as the parser it replaced. There should be no user-visible changes as a result of this, but let us know if you see something wrong.
