Taken straight from the LibreELEC website:
LibreELEC is ‘Just enough OS’ for Kodi, a Linux distribution built to run Kodi on current and popular mediacentre hardware. We are an evolution of the popular OpenELEC project. LibreELEC software will be familiar to OpenELEC users, but the project follows its own path and has intentional differences:
LibreELEC is governed by a project board elected from active team members to set project goals, priorities, and take executive decisions. The board ensures project tasks are distributed among volunteers; we operate on the principle of “many hands make light work” and no project task should ever depend on the skills or efforts of a single person. In the long-term we intend to preserve the collaborative nature of the project by registering LibreELEC as a non-profit charity or foundation.
LibreELEC intends to publish a mid-term release schedule. Our goal is to never leave you (or ourselves) guessing when the next maintenance or public beta release will arrive. Kodi will occasionally provide us with a moving target to hit, but when this happens we will endeavour to communicate, not frustrate.
LibreELEC intends to be a stable and bleeding-edge distribution. Untested and often experimental commits on the bleeding-edge of development will be restricted to our master branch. The active release branch will be frozen at release and future maintenance updates will contain fixes for reported user and security issues plus minor hardware support changes only.
LibreELEC intends to be non-profit in nature with public funding goals and public updates on our progress towards those goals. If you sponsor or donate to the project we guarantee 100% of your funds will be used for project goals.
LibreELEC intends to have minimal advertising on our website and forums. Your donations and a small number of discrete and tasteful spots for commercial sponsors will ensure there’s no need to overload your browser with AdSense.
LibreELEC sponsorships will be for an agreed fixed-term with the responsibilities and expectations of both project and sponsor documented in a Memorandum Of Understanding that is shared with the project team and summarised to our users to ensure broad support and cooperation.
LibreELEC welcomes community builds and encourages people to submit additional projects and device sub-projects to our central GitHub repo. We aren’t going to release or support everything that’s submitted as an official build, but providing a clear development target for emerging and niche hardware will de-fragment community efforts and create a stronger ecosystem around the project. LibreELEC can provide community builders and add-on creators with http://name.libreelec.tv hosting space to publish and a dedicated forum area to support their creations from – and in the longer-term we plan to extend active-user statistics and auto-update capabilities to help our community builders grow and sustain their community
