0.30.0

  • Feature: Introduced major versions for gcc (5, 6, 7) as defaults settings for OSS packages, as minors are compatible by default

  • Feature: VisualStudioBuildEnvironment has added more compilation and link flags.

  • Feature: new MSBuild build helper that wraps the call to msvc_build_command with the correct application of environment
    variables with the improved VisualStudioBuildEnvironment

  • Feature: CMake and Meson build helpers got a new cache_build_dir argument for configure(cache_build_dir=None)
    that will be used to define a build directory while the package is being built in local cache, but not when built locally

  • Feature: conanfiles got a new apply_env attribute, defaulted to True. If false, the environment variables from
    dependencies will not be automatically applied. Useful if you don't want some dependency adding itself to the PATH by default,
    for example

  • Feature: allow recipes to use and run python code installed with conan config install

  • Feature: conanbuildinfo.cmake now has KEEP_RPATHS as argument to keep the RPATHS, as opposed to old SKIP_RPATH which
    was confusing. Also, it uses set(CMAKE_INSTALL_NAME_DIR "") to keep the old behavior even for CMake >= 3.9

  • Feature: conan info is able to get profile information from the previous install, instead of requiring it as input again

  • Feature: tools.unix_path support MSYS, Cygwin, WSL path flavors

  • Feature: added destination folder argument to tools.get() function

  • Feature: SystemPackageTool for apt-get now uses --no-install-recommends automatically.

  • Feature: visual_studio_multi generator now uses toolsets instead of IDE version to identify files.

  • Fix: generators failures print traces to help debugging

  • Fix: typos in generator names, or non-existing generator now raise an Error instead of a warning

  • Fix: short_paths feature is active by default in Windows. If you want to opt-out, you can use CONAN_USER_HOME_SHORT=None

  • Fix: SystemPackageTool doesn't use sudo in Windows

  • BugFix: Not using parallel builds for Visual<10 in cmake build helper

  • Deprecation: conanfile_directory shouldn't be used anymore in recipes. Use source_folder, build_folder, etc

    Breaking changes

    • scopes have been completely removed. You can use environment variables, or the conanfile.develop or conanfile.in_local_cache
      attributes instead.
    • Command test_package has been removed. Use conan create instead, and conan test for just running package tests.
    • werror behavior is now by default. Dependencies conflicts will now error, and have to be fixed.
    • short_paths feature is again active by default in Windows, even with Py3.6 and system LongPathsEnabled.
    • ConfigureEnvironment and GCC build helpers have been completely removed
