## Highlights - Bitrise CLI v1.12.0 available on all stacks: [Monthly release of Bitrise CLI tools and summary of updates (January, 2018) - CLI v1.12.0](http://discuss.bitrise.io/t/monthly-release-of-bitrise-cli-tools-and-summary-of-updates-january-2018-cli-v1-12-0/3682) ### Android/Linux stacks - Ruby upgrade: from `2.4.3` to `2.5.0` ([Update ruby to 2.5.0 by ghaabor · Pull Request #166 · bitrise-io/bitrise-base · GitHub](https://github.com/bitrise-docker/bitrise-base/pull/166)) **Update** : one more important change on the Linux/Android stacks: we changed the default docker image registry from [https://hub.docker.com](https://hub.docker.com) to [https://quay.io](https://quay.io) The images are identical (e.g. [bitriseio/android-ndk - Docker Image](https://hub.docker.com/r/bitriseio/android-ndk/) and [Quay](https://quay.io/repository/bitriseio/android-ndk)) but from now we’ll use [quay.io](http://quay.io) as the default registry instead of [hub.docker.com](http://hub.docker.com) Of course the images are available in both registries, but if you build your own image on top of ours we suggest you to switch to our [quay.io](http://quay.io) images as the base. For reference these are the current pre-cached images on the Android/Docker/Ubuntu16 stack: ```auto + docker images REPOSITORY TAG IMAGE ID CREATED SIZE quay.io/bitriseio/android-ndk latest 7d8b644eb156 4 hours ago 20.5GB quay.io/bitriseio/android latest 415222134aab 4 hours ago 17.6GB quay.io/bitriseio/bitrise-base latest 40c7e729a4ad 5 hours ago 1.93GB ``` ### Xcode stacks - No significant change ### Visual Studio for Mac stacks - Visual Studio for Mac, Beta channel update: [https://releases.xamarin.com/preview-release-15-6-preview-2/](https://releases.xamarin.com/preview-release-15-6-preview-2/) - Visual Studio for Mac, Stable channel update: [https://releases.xamarin.com/service-release-15-5-3/](https://releases.xamarin.com/service-release-15-5-3/) ### Hybrid stacks - No significant change ## This week’s changes (diffs) > ## Stack System Reports You can find the full system report of all of the available Stacks on GitHub: [https://github.com/bitrise-io/bitrise.io/tree/master/system\_reports](https://github.com/bitrise-io/bitrise.io/tree/master/system_reports).

**Update** : one more important change on the Linux/Android stacks: we changed the default docker image registry from [https://hub.docker.com](https://hub.docker.com) to [https://quay.io](https://quay.io) The images are identical (e.g. [https://hub.docker.com/r/bitriseio/android-ndk/](https://hub.docker.com/r/bitriseio/android-ndk/) and [https://quay.io/repository/bitriseio/android-ndk](https://quay.io/repository/bitriseio/android-ndk)) but from now we’ll use [quay.io](http://quay.io) as the default registry instead of [hub.docker.com](http://hub.docker.com) Of course the images are available in both registries, but if you build your own image on top of ours we suggest you to switch to our [quay.io](http://quay.io) images as the base. ---
