Support length

After the release of a new major SabreDAV (for example, 1.8.0), we will promise to support the previous version 1.7.* for at least 12 months.

Currently and previously supported versions:

Versioning scheme

SabreDAV uses three digits for versions. x.y.z.

The first part, x, is reserved for major overhauls of SabreDAV.

The y part is also for fairly large releases. We try to have one or two of these per year, but this fluctuates.

The z is reserved for minor upgrades.

If you are upgrading from a version, to a version that only changes the last digit, it should always be safe to do so.

To do this with composer, just run:

composer update sabre/dav

This should automatically do all the work. This should be 100% risk free, except in cases where we are fixing a major security issue, and we are not able to do so, without breaking backwards compatibility.

This means an upgrade from 2.1.2 to 2.1.3 is always safe. Upgrading from 2.0.6 to 2.1.0 is not.

For versions where we are changing x or y, we almost always want to break backwards compatibility in some areas. Depending on what features you are using in SabreDAV you may or may not be affected by this.

Alpha and beta versions

Alpha and beta versions always have the word 'alpha' or 'beta' in them. In alpha versions it is highly likely that we are not done yet, and will still want to make changes.

Beta versions should not get any BC-breaking changes, but they still may.
