1.0.0-beta1 (22-December-2017)

1.0.0-beta1

Install with: pip install conan==1.0.0b1

• Feature: New command line UI. Most commands use now the path to the package recipe, like conan export . user/testing
  or conan create folder/myconanfile.py user/channel.
• Feature: Better cross-compiling. New settings model for os_build, arch_build, os_target, arch_target.
• Feature: Better Windows OSS ecosystem, with utilities and settings model for MSYS, Cygwing, Mingw, WSL
• Feature: package() will not warn of not copied files for known use cases.
• Feature: reduce the scope of definition of cpp_info, env_info, user_info attributes to package_info()
  method, to avoid unexpected errors.
• Feature: extended the use of addressing folder and conanfiles with diffeent names for source, package and export-pkg
  commands
• Feature: added support for Zypper system package tool
• Fix: Fixed application of build requires from profiles that didn't apply to requires in recipes

• Deprecation: Removed self.conanfile_directory attribute.

Breaking changes

• The new command line UI breaks command line tools and integration. Most cases, just add a . to the command.
• Removed self.copy_headers, self.copy_libs, methods for package(). Use self.copy() instead.
• Removed self.conanfile_directory attribute. Use self.source_folder, self.build_folder, etc.
  instead

0.30.0 (12-December-2017)

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

0.29.2 (2-December-2017)

0.29.2

• Updated python cryptography requirement for OSX due the pyOpenSSL upgrade. See more: https://pypi.python.org/pypi/pyOpenSSL

• Feature: AutoToolsBuildEnvironment now auto-loads pkg_config_path (to use with pkg_config generator)
• Feature: Changed search for profiles. Profiles not found in the default profiles folder, will be searched for locally. Use ./myprofile to force local search only.
• Feature: Parallel builds for Visual Studio (previously it was only parallel compilation within builds)
• Feature: implemented syntax to check options with if "something" in self.options.myoption
• Fix: Fixed CMake dependency graph when using TARGETS, that produced wrong link order for transitive dependencies.
• Fix: Trying to download the exports_sources is not longer done if such attribute is not defined
• Fix: Added output directories in cmake generator for RelWithDebInfo and MinSizeRel configs
• Fix: Locks for concurrent access to local cache now use process IDs (PIDs) to handle interruptions and inconsistent states. Also, adding messages when locking.
• Fix: Not remove the .zip file after a conan config install if such file is local
• Fix: Fixed CMake.test() for the Ninja generator
• Fix: Do not crete local conaninfo.txt file for conan install <pkg-ref> commands.

• Development: Large restructuring of files (new cmd and build folders)
• Deprecation: Removed old CMake helper methods (only valid constructor is CMake(self))
• Deprecation: Removed old conan_info() method, that was superseded by package_id()

Breaking changes

• CMAKE_LIBRARY_OUTPUT_DIRECTORY definition has been introduced in conan_basic_setup(), it will send shared libraries .so
  to the lib folder in Linux systems. Right now it was undefined.
• Profile search logic has slightly changed. For -pr=myprofile, such profile will be searched both in the default folder
  and in the local one if not existing. Use -pr=./myprofile to force local search only.
• The conan copy command has been fixed. To copy all binaries, it is necessary to explicit --all, as other commands do
• The only valid use of CMake helper is CMake(self) syntax
• If using conan_info(), replace it with package_id()

0.28.1 (31-October-2017)

0.28.1

• BugFix: Downloading (tools.download) of files with content-encoding=gzip were raising an exception because the downloaded content length didn't match the content-length

😈 Happy Halloween!

Breaking changes

This is an important release towards stabilizing conan and moving out of beta. Some breaking changes have been done, but mostly to command line arguments, so they should be easy to fix. Package recipes or existing packages shouldn't break.
Please update, it is very important to ease the transition of future stable releases. Do not hesitate to ask questions, or for help, if you need it. This is a possibly not complete list of things to take into account:

• The command conan install doesn't accept cwd anymore, to change the directory where the generator
  files are written, use the --install-folder parameter.
• The command conan build now requires the path to the conanfile.py (optional before)
• The command conan package not longer re-package a package in the local cache, now it only operates in a user local folder. The recommended way to re-package a package is using conan build and then conan export-pkg.
• Removed conan package_files in favor of a new command conan export-pkg. It requires a local recipe with a package() method.
• The command conan source no longer operates in the local cache. now it only operates in a user local folder. If you used conan source with a reference to workaround the concurrency, now it natively supported, you can remove the command call and trust concurrent install processes.
• The command conan imports doesn't accept -d, --dest anymore, use --imports-folder parameter instead.
• If you specify a profile in a conan command, like conan create or conan install the base profile ~/.conan/profiles/default won’t be applied.
  Use explicit include to keep the old behavior.
