## 0.19.3 (2014-10-07)
###### Bug Fixes
* `PlistHelper`: Drop usage of the `CFPropertyList` gem and `plutil` and replace
it with a version that uses the native `CFPropertyList` APIs from the OS X
`CoreFoundation` framework, like the previous C extension did. Except this
time we use Ruby's Fiddle API (MRI >= 1.9.3) to interface with it instead of
the need to compile a C extension.
This release still includes a prebuilt version of the C extension for Ruby
1.8.7 support (OS X 10.8.x), but this will soon be dropped completely.

###### Bug Fixes
* [Scheme] Generate correct ReferencedContainer attribute when the Xcode project
has a non-empty `projectDirPath`.
[Per Eckerdal](https://github.com/pereckerdal)
[#102](https://github.com/CocoaPods/Xcodeproj/pull/102)
###### Enhancements
* [Gem] Provide prebuilt binary versions of the C extension for the stock Ruby
versions on both OS X 10.8 (MRI 1.8.7) and 10.9 (MRI 2.0.0). Due to the ABI
of MRI’s C ext API not always being consistent, these will **not** install on
Ruby versions you have installed yourself. To override the default behaviour
you can use the `XCODEPROJ_BUILD` environment variable. Set it to `1` to
_always_ build the C extension or to `0` to _never_ build the C extension.
[Eloy Durán](https://github.com/alloy)

## 0.13.1 (2013-10-10)
###### Bug Fixes
* Fix `Unable to read data from Model.xcdatamodeld/.xccurrentversion` when
there are more Data model versions.
[Pim Snel](https://github.com/mipmip)
###### Enhancements
* [AbstractTarget] Added default value for `default_configuration_name`
attribute.
[Fabio Pelosin](https://github.com/fabiopelosin)
* [XCConfigurationList] `common_resolved_build_setting` will now ignore nil
values. This is an heuristic which might not closely match Xcode behaviour.
This is done because some information, like the SDK, is usually considered at
the target level but it might actually differ in the build configurations.
For example nothing prevents a target to build with the iOS sdk in one
configuration and with the OS X in another.
[Fabio Pelosin](https://github.com/fabiopelosin)
[CocoaPods/CocoaPods#1462](https://github.com/CocoaPods/CocoaPods/issues/1462)
## 0.13.0 (2013-10-09)
###### Breaking
* [AbstractTarget] The `#sdk` method now raises if the value is not the same
across all the build configurations. This has been done to prevent clients
from accidentally using arbitrary values.
[Fabio Pelosin](https://github.com/fabiopelosin)
###### Enhancements
* [AbstractTarget] Added `#resolved_build_setting` and
`#common_resolved_build_setting`.
[Fabio Pelosin](https://github.com/fabiopelosin)
* [XCConfigurationList] Added `#get_setting` and `#set_setting`.
[Fabio Pelosin](https://github.com/fabiopelosin)
* [Project] Added `#build_configuration_list`.
[Fabio Pelosin](https://github.com/fabiopelosin)
## 0.12.0 (2013-10-08)
###### Breaking
* [PBXGroup] `#new_static_library` has been replaced by the more versatile
`#new_product_ref_for_target`.
[Fabio Pelosin](https://github.com/fabiopelosin)
* [XCScheme] Overhauled interface to support multiple targets.
[Jason Prado](https://github.com/jasonprado)
[#95](https://github.com/CocoaPods/Xcodeproj/pull/95)
* [PBXGroup] renamed `#recursively_sort_by_type` to
`#sort_recursively_by_type`.
[Fabio Pelosin](https://github.com/fabiopelosin)
###### Enhancements
* [PBXNativeTarget] `#add_system_framework` now adds the system frameworks
relative to the developer directory. Xcode behaviour is following: if the
target has the same SDK of the project it adds the reference relative to the
SDK root otherwise the reference is added relative to the Developer
directory. This can create confusion or duplication of the references of
frameworks linked by iOS and OS X targets. For this reason the new Xcodeproj
behaviour is to add the frameworks in a subgroup according to the platform.
The method will also honor the SDK version of the target if available
(otherwise the last known version is used).
[Fabio Pelosin](https://github.com/fabiopelosin)
* [Project] The project can now recreate it schemes from scratch and optionally
hide them.
[Fabio Pelosin](https://github.com/fabiopelosin)
* Added support for booleans in the C extension which handles Property list
files.
[Fabio Pelosin](https://github.com/fabiopelosin)
* Improvements to the generation of new targets.
[Fabio Pelosin](https://github.com/fabiopelosin)
* [Project] Added possibility to specify the position of groups while sorting.
[Fabio Pelosin](https://github.com/fabiopelosin)
* [PBXGroup] Now defaults to sorting by name.
[Fabio Pelosin](https://github.com/fabiopelosin)
* [XCScheme] The string representation of schemes now closely matches Xcode
behaviour.
[Fabio Pelosin](https://github.com/fabiopelosin)
* [PBXGroup, PBXFileReference] Added `#parents`.
[Fabio Pelosin](https://github.com/fabiopelosin)
* [PBXGroup] Added `#recursive_children_groups`.
[Fabio Pelosin](https://github.com/fabiopelosin)
* [AbstractTarget] Add #sdk_version.
[Fabio Pelosin](https://github.com/fabiopelosin)
* Added default build settings to new projects according to Xcode defaults.
[Fabio Pelosin](https://github.com/fabiopelosin)
## 0.11.1 (2013-09-21)
###### Bug Fixes
* No longer allow `PBXTargetDependency` to sort recursively. When two targets
depend on each other, this would lead to the two targets endlessly sorting
each other and finally crashing with a stack overflow.
[Eloy Durán](https://github.com/alloy)
[CocoaPods#1384](https://github.com/CocoaPods/CocoaPods/issues/1384)
## 0.11.0 (2013-09-20)
###### Breaking
* Added support for Xcode 5.
* The `ARCHS` option is not set anymore and will use Xcode’s defaults. This
fixes the build and archive issue with the new `arm64` architecture.
[CocoaPods#1352](https://github.com/CocoaPods/CocoaPods/issues/1352)
* The default of the `ONLY_ACTIVE_ARCH` setting has changed to `YES`
in the `Debug` configuration. This means that if this is a static library,
the application that links the library in will have to make the same
adjustment, or the build will fail.
* [Project] `#add_system_framework` has been removed in favor of
`PBXNativeTarget#add_system_framework`.
###### Enhancements
* [Command] Added new subcommand `sort`, to sort projects from the command
line. This command is useful for sorting projects as well to easy comparison
of existing projects.
* [Project::Object] Added `#sort`.
* [Project] Added `#sort`, `#add_system_library`.
* [Project::ObjectList] Added `#move` and `#move_from`.
* [PBXNativeTarget] Improve `#add_dependency` to avoid duplicates.
* [PBXNativeTarget] Added `#add_system_framework`, `#add_system_frameworks`,
`#add_system_library`, `#add_system_libraries`.
* [PBXFileReference, PBXGroup] Added `set_source_tree` and `#set_path`.
* [PBXGroup] Added `find_file_by_path`.
* [AbstractBuildPhase] Added `#file_display_names`, `#build_file`, and `#include`.
###### Bug Fixes
* [Command] Fixed opening existing projects.
* [GroupableHelper] Improved handling of ambiguous parents.
* Decode XML entities in project paths when reading workspace files. This
prevents double-encoding the entities (for example, `&apos;`) when writing
the file.
[amolloy](https://github.com/amolloy)
* Fix C-ext memory leak by closing and releasing the CFWriteStream used to write
projects when done.

* Build configurations are now deeply copied.
[CocoaPods/CocoaPods#1288](https://github.com/CocoaPods/CocoaPods/issues/1322),
## 0.10.0 (2013-09-04)
###### Breaking
* To initialize a project a path is required even is the project is being
initialized from scratch.
* To open an existing project `Xcodeproj::Project.open` should be used in place
of `Xcodeproj::Project.new`, which now is deprecated for that purpose.
* `Project#save_as` has been renamed to `Project#save` which uses the path
provided during initialization by default.
* The parameter to specify a subgroup of the helper methods to create file
references and new groups (e.g. `#new_file`, `#group`) has been deprecated.
* Removed `PBXGroup#new_xcdatamodel_group`.
* [PBXFileReference] `#update_last_known_file_type` has been renamed to
`#set_last_known_file_type`. Added `#set_explicit_file_type`.
* [PBXGroup] Renamed `#sort_by_type!` to `#sort_by_type`.
* [Project] `#add_system_framework` now adds the reference to the frameworks
build phase of the target as well.
###### Enhancements
* CoreData versioned models are now properly handled respecting the contents of
the `.xccurrentversion` file.
[CocoaPods/CocoaPods#1288](https://github.com/CocoaPods/CocoaPods/issues/1288),
[#83](https://github.com/CocoaPods/Xcodeproj/pull/83)
[Ashton-W](https://github.com/Ashton-W)
* [PBXGroup, PBXFileReference] Improved source tree handling in creation
helpers. Now it is possible to specify the source tree which will be used to
adjust the provided path as needed.
* Added `PBXGroup#parent`, `PBXGroup#real_path`, `PBXFileReference#parent`
(replaces `#group`), and `PBXFileReference#real_path`.
* Xcodeproj will automatically utilize the
[xcproj](https://github.com/0xced/xcproj) command line tool if available in
the path of the user to touch saved projects. This will result in projects
serialized in the exact format used by Xcode.
* [PBXGroup] Improved deletion.
* [PBXGroup] Added `#recursively_sort_by_type`.
* [PBXGroup, PBXFileReference] Added `#move`.
* [AbstractTarget] Added `#add_build_configuration`.
## 0.9.0 (2013-08-02)
###### Enhancements
* Frameworks are added using the last sdks version reported by the xcodebuild if
the target links against the last SDK.
* Improvements in the handling of file references to frameworks.
* Improvements to the schemes logic.
* Added support for resources bundle targets.
* Project::Group#new_file will now create XCVersionGroup for xcdatamodeld file.
###### Bug Fixes
* The file type of the frameworks file references has be corrected.
