A time-line of past dCache releases and anticipated future dCache series (Large version).

Release Policy

dCache follows a timeboxed two dimensional release policy. Every three months we produce a feature release. Feature releases have version numbers 2.x.0, where x is a positive integer. Each feature release is followed up by a number of maintenance releases containing bug fixes or high priority feature tweaks. Maintenance releases for release 2.x.0 have version numbers 2.x.y, for y being an integer larger than 0. For example; 2.0.0 is a feature release, 2.0.1 is the first maintenance release for the 2.0-series and 2.0.2 is the second maintenance release.

A feature release is maintained for four months during which regular maintenance releases are made. We strive to make a final release within the last two weeks of those four months. Long term support releases (the "Golden Releases") are maintained for at least 2 years.

Recommended Releases

At any point in time, dCache.org will recommend one or more releases. Recommended releases are marked green below. Unless you have a reason not to do so, we urge you to use recommended releases on production systems.

Other releases are considered stable, however care should be taken as such releases may only have received a limitted amount of public testing. Unless you have reason to do otherwise, we urge you to not install or upgrade to these release series unless you are already using that particular release series.

Any change comes with a risk of introducing bugs. We urge all sites to carefully test each release with their setup before upgrading a production system. Upgrading to a newer maintenance release within the same release series is however a relatively low risk step and we strongly recommend to always use the latest maintenance release.

If you use repackaged versions of dCache not provided by dcache.org, for instance from OSG, EMI, gLite or NDGF, then the provider may recommended a different version. In that case use the version recommended by the provider.

Golden Releases

Golden releases are our long term support releases. These release series will receive updates for typically two years, with amble overlap between releases to allow sites to upgrade to the next Golden Release.

The release schedule of golden releases is adjusted to match the WLCG and LHC schedules.

We support upgrading from one golden release to the next and provide detailed upgrade instructions. We do however not explicitly support "skipping" golden releases. We therefore recommend that a site that uses a golden release plans for upgrading to the next golden release when such a release becomes available and no later than the end of life of the previous golden release.

Choosing between golden releases and regular releases is a matter of site policy and a matter of taste. Using regular releases means upgrading more often, and each feature release comes with a risk of introducing bugs. On the other hand it means the upgrade process is more incremental, with less drastic changes between each release. One also gets early access to new features, performance improvements, and low priority bug fixes.

Upgrade instructions

Non-pool nodes must belong to the same feature release, but may use different patch level releases. That is, version 2.x.y is compatible with 2.x.z; under the older release numbers 1.9.x-y is compatible with 1.9.x-z. Pool nodes (which do not have any doors or other dCache services) belonging to different feature releases can be mixed to some extend. Please consult the compatibility matrix of the release notes for details.

We try to avoid configuration and schema changes in maintenance releases. Moving from one feature release to another may require configuration changes during upgrade. We provide three upgrade guides from one golden release to the next (1.9.5 to 1.9.12, 1.9.12 to 2.2, 2.2 to 2.6), whereof the upgrade guide from 2.2 to 2.6 is a preliminary version at the moment and a document for the migration from the /opt layout to the FHS compliant layout.

In addition to the usual improvements and bug fixes, dCache 2.6 focuses on:

If you upgrade from dCache 2.2 to dCache 2.6, please read the preliminary version of the Ultimate Golden Release Upgrade Guide carefully.

dCache 2.6 requires Java-7.

Sites upgrading to 2.6.x and runnig postgresql < 9.2 should be aware that due to an unfortunate behaviour of postgresql the automated database schema migration which is applied on startup of dCache may take a lot of time (e.g. 3 hours for 20 million files).

Requires Java-7.

Sites upgrading to 2.5.x and runnig postgresql < 9.2 should be aware that due to an unfortunate behaviour of postgresql the automated database schema migration which is applied on startup of dCache may take a lot of time (e.g. 3 hours for 20 million files).

Please note that due to a regression introduced in dCache 2.5.0, which has been fixed in dCache 2.5.2, dCache 2.5.2 is not compatible with dCache 2.5.0 or dCache 2.5.1.
