The CSS Snapshot

http://www.w3.org/TR/css-2015/

First update since 2010

What is the Snapshot

[...] includes only specifications that we consider stable and for which we have enough implementation experience that we are sure of that stability.

Unstable feature policy

Before

Release early

Use prefixes

-webkit-foo: bar;
-moz-foo: bar;
-ms-foo: bar;
-o-foo: bar;
foo: bar;

After

Release when stable

Use flags until then

Alias prefixed and unprefixed syntax if you break the rule
