0.29.0 (21-November-2017)

0.29.0

• Feature: Support for WindowsStore (WinRT, UWP)
• Feature: Support for Visual Studio Toolsets.
• Feature: New boost-build generator for generic bjam (not only Boost)
• Feature: new tools.PkgConfig helper to parse pkg-config (.pc) files.
• Feature: Added self.develop conanfile variable. It is true for conan create packages and for local development.

• 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.

• Deprecation: Removed old conan_info() method, that was superseded by package_id()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)

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.

0.25.0 (19-July-2017)

0.25.0

This release introduces a new layout for the local cache, with dedicated export_source folder to store the source code exported with exports_sources feature, which is much cleaner than the old .c_src subfolder. A migration is included to remove from the local cache packages with the old layout.
