Version numbers

Version numbers mostly reflect how much change the underlying code has undergone since the previous releases. See Roadmap & Unified Process. Version numbers do not really reflect how many new features may or may not be available. Please refer to the following table for more information about each release.

Stability

We use the following indicators:

• Alpha: Consider it as a demo release. Do not run on production.
• Beta: The version is usable. Only run on production if you're ready to apply PHP patches by hand. Occasionnally, a beta may prove stable and not require any patching at all. ;)
• Release Candidate (RC): There may be remaining minor bugs but nothing bad. It is safe to run on production.
• No special label: This is considered a stable release.

We do our best to release the most stable possible versions. However, no one is getting paid for doing Quality Assurance, so problems may arise after release time. The level of stability for each version will be reported in the table below. Look for the green checks .
