NGINX Full Version

Introducing NGINX 1.12 and 1.13

Today we’re pleased to announce the availability of NGINX Open Source 1.12 and 1.13. These version numbers define the stable and mainline branches, respectively, of NGINX Open Source. We will focus on developing and improving these two branches for the next 12 months.

NGINX version 1.12.0 was released today, and the next feature release of our mainline branch will be numbered 1.13.0.

NGINX Version Numbering Overview

NGINX, Inc. manages two NGINX source code branches:

Each year, we create a new fork from our mainline branch which becomes the new stable branch. Version 1.12.0 is forked from 1.11.13, the last release of the prior mainline branch (1.11). The previous stable branch, 1.10, is now deprecated and we will no longer be updating or supporting it. Development will continue on the 1.13 mainline branch.

We generally recommend using the mainline branch. This is where we commit all new features, performance improvements, and enhancements. We actively test and QA the mainline branch, so it’s arguably more stable than the “stable” branch. The mainline branch is also the source of NGINX Plus builds for our commercial customers.

If you want to minimize the number of updates you need to deploy and don’t anticipate an urgent need for any of the features planned for the next 12 months, the stable branch is a good choice.

NGINX 1.11 in Review

The past year was another busy one for NGINX development. We added a number of new features and capabilities to the 1.11 mainline branch: dynamic modules, IP Transparency, improved TCP/UDP load balancing, better caching performance, and more.

NGINX 1.11 also saw numerous other feature improvements, bug fixes, and other enhancements, making this series of releases the largest development of NGINX in its recent history (check out the release notes for a full list of changes in 1.11). Only a small number of changes needed to be backported to the 1.10 stable release, a clear testament to the high standards of quality and reliability our engineering team maintains.

In the past year we also started a project to better document NGINX. As part of that effort we released the NGINX development guide, which documents NGINX internals. Though still a work in progress, it thoroughly describes our internal data structures, how we manage memory, how event handling works, and other aspects of NGINX’s internal architecture.

We also hit a major milestone in NGINX adoption in the past year. Although we don’t set out to compete or take market share from other web servers, it’s gratifying to see continued steady growth in the use of NGINX. This January, we became the web server for the majority of the world’s 100,000 busiest websites, a distinction we also hold for the 1,000 and 10,000 busiest sites.

Looking Forward to NGINX 1.13

The NGINX 1.13 release series also promises to bring significant advances, including enhancements to HTTP/2 and caching capabilities. We will also be making continual improvements to the NGINX JavaScript module in terms of JavaScript language support and to enable even more sophisticated programmatic configuration. The demands of modern, distributed, microservices applications are also driving part of our roadmap, and more will be shared at our annual user conference, nginx.conf 2017, this September 6–8 in Portland, OR.
