Fast, lightweight, free CMS?

Question

CMS

The functionality should not be burdened with various modules of forums, boards, guest books, and other unnecessary things. Is that the ability to add news (a brief description with a link to the full text). The main functionality will consist of a third-party service API, only a skeleton is required from the CMS. You will also need static pages, with the ability to create them. Subject of the project: sale of railway and air tickets with the possibility of searching and booking hotels.
Must be modern (authorization / registration through social networks, for example), be aware of trends (markup, possibly adaptability, latest versions of languages, modern libraries). If possible with easily changeable design.
Russian support is not required, but optional.
What you use and what you are ready to recommend. A huge request: do not recommend monsters like WordPress, Joomla, ModX, Drupal, and others like them.
Thanks for the replies!

Answer 4

Try CleverStyle CMS - fast, light, free, nothing extra in the core, and then as you wish.
Regarding trends: support for Composer, Bower, NPM without having to put anything on the server and generally have access to exec() calls (you don't even need to have Node.js), web components (+Polymer) and hacked versions of libraries to support work with shadow trees out of the box.
Russian support from me) The repository has a wiki with documentation in English.
Now the 3.x series is in development, the transition to Polymer 1.1 has been made, which is not backward compatible with 0.5, so part of the interface is temporarily broken. It will be fixed in the near future, but for now you can try the latest stable version from the 2.x series.
It's not even a CMS, but a CMF, just what you need. oAuth2 server and RESTful API support is also available.
