Marlin 1.1 represents an evolutionary leap over Marlin 1.0.2. It is the result of over two years of effort by several volunteers around the world who have paid meticulous and sometimes obsessive attention to every detail. For this release we focused on code quality, performance, stability, and overall user experience. Several new features have also been added, many of which require no extra hardware.
For complete Marlin documentation click over to the [Marlin Homepage <marlinfw.org>](http://marlinfw.org/), where you will find in-depth articles, how-to videos, and tutorials on every aspect of Marlin, as the site develops. For release notes, see the [Releases](/MarlinFirmware/Marlin/releases) page.
## Stable Release Branch
This Release branch contains the latest tagged version of Marlin (currently 1.1.0 – May 2017).
Previous releases of Marlin include [1.0.2-2](/MarlinFirmware/Marlin/tree/1.0.2-2) (December 2016) and [1.0.1](/MarlinFirmware/Marlin/tree/1.0.1) (December 2014). Any version of Marlin prior to 1.0.1 (when we started tagging versions) can be collectively referred to as Marlin 1.0.0.
## Contributing to Marlin
Click on the [Issue Queue](/MarlinFirmware/Marlin/issues) and [Pull Requests](/MarlinFirmware/Marlin/pulls) links above at any time to see what we're currently working on.
To submit patches and new features for Marlin 1.1 check out the [bugfix-1.1.x](/MarlinFirmware/Marlin/tree/bugfix-1.1.x) branch, add your commits, and submit a Pull Request back to the `bugfix-1.1.x` branch. Periodically that branch will form the basis for the next minor release.
Note that our "bugfix" branch will always contain the latest patches to the current release version. These patches may not be widely tested. As always, when using "nightly" builds of Marlin, proceed with full caution.
## Current Status: In Development
Marlin development has reached an important milestone with its first stable release in over 2 years. During this period we focused on cleaning up the code and making it more modern, consistent, readable, and sensible.
## Future Development
Marlin 1.1 is the last "flat" version of Marlin!
Arduino IDE now has support for folder hierarchies, so Marlin 1.2 will have a [hierarchical file structure](/MarlinFirmware/Marlin/tree/breakup-marlin-idea). Marlin's newly reorganized code will be easier to work with and form a stronger starting-point as we get into [32-bit CPU support](/MarlinFirmware/Marlin/tree/32-Bit-RCBugFix-new) and the Hardware Access Layer (HAL).
Additional documentation can be found at [The Marlin Documentation Project](https://www.marlinfw.org/).
Please test this firmware and inform us if it misbehaves in any way, volunteers are standing by!
## Release Candidate -- Marlin 1.1.0-RCBugFix - 6 Dec 2016
__Not for production use – use with caution!__
You can download earlier versions of Marlin on the [Releases page](https://github.com/MarlinFirmware/Marlin/releases). (The latest "stable" release of Marlin is 1.0.2-1.)
The latest Release Candidate lives in the ["RC" branch](https://github.com/MarlinFirmware/Marlin/tree/RC). Bugs that we find in the current Release Candidate are patched in the ["RCBugFix" branch](https://github.com/MarlinFirmware/Marlin/tree/RCBugFix), so during beta testing this is where you can always find the latest code on its way towards release.
