    * Small, frequent upgrades are easier to manage than large, infrequent upgrades. 
    * Development freezes longer than a week don't work. 
    * You can't make volunteers produce work on defined schedules. 
    * Feature-based releases expand to fill all available time until someone feels
      guilty for not finishing the feature on a magical, wish-fulfillment schedule,
      and hey, has it been a couple of years already? 
    * A release with even one improvement over the previous release is worth
      releasing on a time-based schedule. 
    * (Almost) no one but contributors will test an alpha, beta, gamma, or release
      candidate in the same way that (almost) no one but contributors wants to run
      nightly trunk builds. 
    * The only reliable way to get real feedback from real
      users is to give them a real release. 
    * Users may complain that a feature doesn't exist, but at a fraction of the
      volume than if you remove a feature they thought they might want. 
    * Handing boring scut-work to volunteers is a great way to reduce their
      motivation. 
    * It's possible to release software every month without burning out volunteers,
      patch managers, pumpkings, release managers, or testers -- and the software 
      can get better every month.
    * Revision numbers are meaningless, except insofar as they increase
      monotonically. Revision identifiers (alpha, beta, release candidate) are
      evidence of an unhealthy release process. 
    * Rapid deprecation cycles are okay if you provide migration tools. 
    * Supporting more than two stable versions of a piece of software purely
      through volunteer effort is crazy. 
    * If downstream makes substantial changes to the code or to the release
      process, downstream has just volunteered to support those changes. 
    * If your project is under active development, the longer the period between
      stable releases, the less relevant your project is. 
    * Users who want critical bug fixes and new features without actually upgrading
      their software also want magic flying candy-dropping ponies.
