sabre/dav 3.0 released
We just tagged and zipped the sabre/dav 3.0 release. This is only a year after the 2.0 release, but 6 years after the 1.0 release.
This means we needed 440% less time to release. If we continue to increase speed at this rate, it means we should get a 4.0 release in august, and somewhere in september we will average 1 major release per hour.
Lets hope that's not the case though, because writing these blogposts would get old rather quickly.
Anyway, back to the subject at hand:
The browser plugin has received a lot of subtle upgrades that should make it easier to use. We've removed some of the information that was not useful 99% of the time, and added the ability to create new principals in the browser.
Authentication system overhaul
The authentication system and backends got a new API, which allows for cleaner implementation in many cases, and also adds the ability to run multiple authentication backends cooperatively.
This allows the implementor to support HTTP Auth, as well as for example OAuth2, or any custom schemes.
Nearly all XML code got rewritten
Back then these api's were rather unstable and had a big number of problems. In 2012 I started again, and since then have been working on a separate sabre/dav branch to implement this.
After many hundreds of commits, it's finally done. The new xml system is based on a new sabre/xml library and has made the xml code a lot more legible and in some cases faster.
Furthermore, it will in the future allow us to make further optimizations that were not possible before, due to the fact that this new system can read and write XML from and to streams, whereas the DOM had no other option but to keep objects in memory (which would become in some instances absolutely massive).
MKCOL can now create new principals
If your backend has support for it, new principals can now be programmatically created.
Support for a "home"-like collection
We added a new collection type that can automatically create a "home" directory for every principal, protected by ACL rules.
Property storage can now store any complex XML property
A lot of smaller changes have been made since version 2.1. You can find more details in the ChangeLog. Read from 2.2.0-alpha1 onwards, as most changes have been made in the alpha versions.
As always, the zip can be found on the github releases page, but the recommended installation method is using composer:
composer require sabre/dav ~3.0.0
A few backwards compatibility breaks have been made in this release.
If you are running a standard server, it's likely that you only have to run the database upgrade script, but if you did any sort of customizations, chances are that you need to make changes in your code to keep stuff running.
Make a backup. and then head to the migration instructions for 3.0.
Due to the 3.0 release, 2.1 now enters maintenance mode. This means that version 2.1 of sabre/dav will be actively maintained for the next 12 months.
More information about previous versions and their support status can be found on the upgrade page.
Thanks as always!!!
