How updates & versioning work

The platform version (shown in the admin sidebar footer and the public site footer) follows a simple scheme while the platform is pre-1.0:

• A batch of features or multiple changes bumps the third number (0.8.9 → 0.8.10).
• A small, one-off tweak adds or increments a fourth number (0.8.10 → 0.8.10.1).
• A genuinely new subsystem (site templates, self-service trials, the site importer, the calendar) still bumps that same third number — there’s no separate “major feature” number while the platform is pre-1.0.

Every update bumps the version in lockstep across the admin panel and the public site, and adds a matching entry to the What’s New changelog — so the number you see always matches a specific, documented set of changes.
