Road Map / Development Wish List for OpenAFS

In its fifteen-plus years as an open-source project, OpenAFS has made great progress and proved to be a mature project, providing clients and servers on all UNIX/Linux variants.

Road Map

As an independent open-source project, OpenAFS has no paid staff or full-time developers to maintain the software and add new features. The contributions of volunteers drive the pace of progress, so there cannot be fixed timelines for future plans. Regardless, there is still an overarching plan for the desired trend of future development, with major features and milestones to be reached. Please send inquiries, comments, and offers of support to Where external contributors have promised contributions, they are included, as are timelines when those are provided. The following release schedule is subject to change.


The next release in the stable series for Unix will bring additional incremental improvements in line with previous stable branch releases. Most noteworthy, it will include fixes that prevent cases where a database write could be lost or an old version of the database be used instead of the latest version.

The 1.6 stable release series is nearing the end of its development lifecycle; development resources are shifting to the forthcoming 1.8 release series. Non-invasive bugfixes and OS support will continue to be merged to the 1.6 series, with OS support expected to drive the release schedule.

No firm end-of-life date is yet set, as that will depend on the timeline for the 1.8 release to be available.


The 1.7.33 release is the latest release from the 1.7 series of stable releases for Windows clients. No additional releases from this series are currently planned.

Starting from the 1.7.32 release, 1.7-series releases are only distributed from in source form. Pre-built installers are available from third-party organzations.


Preparation for a new stable release series for Unix has begun. This release will bring a wide variety of improvements and features that have been developed on the master branch for the past several years. In addition to the general code cleanup that has accumulated, it will include support for pthreaded database servers, shared libraries built with libtool, and use the crypto and roken libraries from Heimdal, eliminating the broad reliance on libkrb5 for rxkad-k5 support. The Rx protocol performance is improved, and private structures have been removed from the public header files. The most recent status update for this release was posted to openafs-devel is available here.


The 1.9 series will be an experimental release series, producing a rapidly updating set of releases to facilitate access to the features being developed for the 2.0 release.


One of the goals of the 1.8 release is to open up the tree for more invasive (and more rewarding) feature development. One long-desired feature that is expected to be in 2.0 is the rxgk Rx security class; some preliminary changes toward that feature are in gerrit waiting for review. Other desired features such as IPv6 support are listed below, but as always, are contingent on the contributions of volunteers and companies to make them happen.

Development Wish List

Modernization of crypto and network support

Over the years, the AFS protocol has not kept up with developments in cryptography and network protocols, sticking with single-DES-grade encryption and remaining an IPv4-only service. The 2013 security release moved the long-term krb5 cell-wide keys off of single-DES, but wire encryption remains unchanged since the original AFS release.
