Te falto añadir que es la más estable...
Reynier, en el propio sitio de las descargas de MySQL (
http://dev.mysql.com/downloads/) fijate que aparece la version 4.0.x como la recomendada.
Cita: MySQL database server & standard clients: - MySQL 4.0 -- Generally Available (GA) release (recommended)
- MySQL 4.1 -- Gamma release (use this for new development)
- MySQL 5.0 -- Alpha release (use this for previewing and testing new features)
- MySQL 5.0.1 -- Snapshot release (use this for previewing and testing new features)
- Older releases -- older releases (only recommended for special needs)
