      BIND 9.13 is an unstable development release of BIND.
64
      This document summarizes new features and functional changes that
Tinderbox User's avatar

65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91
      have been introduced on this branch.  With each development release
      leading up to the stable BIND 9.14 release, this document will be
      updated with additional features added and bugs fixed.
    </p>
  </div>

  <div class="section">
<div class="titlepage"><div><div><h3 class="title">
<a name="relnotes_versions"></a>Note on Version Numbering</h3></div></div></div>
    <p>
      Prior to BIND 9.13, new feature development releases were tagged
      as "alpha" and "beta", leading up to the first stable release
      for a given development branch, which always ended in ".0".
    </p>
    <p>
      Now, however, BIND has adopted the "odd-unstable/even-stable"
      release numbering convention. There will be no "alpha" or "beta"
      releases in the 9.13 branch, only increasing version numbers.
      So, for example, what would previously have been called 9.13.0a1,
      9.13.0a2, 9.13.0b1, and so on, will instead be called 9.13.0,
      9.13.1, 9.13.2, etc.
    </p>
    <p>
      The first stable release from this development branch will be
      renamed as 9.14.0. Thereafter, maintenance releases will continue
      on the 9.14 branch, while unstable feature development proceeds in
      9.15.
