###### Enhancements
- Released preview [documentation](docs.cocoapods.org).
- CocoaPods now has support for working in teams and not committing the Pods folder.
- Released [documentation](docs.cocoapods.org).
- CocoaPods now can infer the platform from the integrated targets.
- Adds new subcommand `pod spec cat NAME` to print a spec file to standard output.
- Added Podfile to the Pods project.
- The `--no-clean` option of the `pod spec lint` command now displays the Pods project for inspection.
- CocoaPods now can infer the platform from the integrated targets.
- It is now possible to specify default values for the configuration in `~/.cocoapods/config.yaml`.
- CocoaPods now keeps track of the checksum of the specifications of the installed Pods and reinstalls them if needed.
- It is now possible to specify default values for the configuration in `~/.cocoapods/config.yaml` ([example]()).
- CocoaPods now checks the checksums of the installed specifications and reinstalls them if needed.
