<H3 class=docSection1Title>6.1 Summary of Changes</H3>
<P class=docText>Developmental releases of Ruby always have an
odd minor revision number such as 1.5 or 1.7. Once a
developmental release is stable and finalized, it's then
"promoted" to a stable release. Stable releases always have an
even minor revision number such as 2.0 or 3.2. Therefore,
releases with even subversion numbers (1.4, 1.6, 1.8, etc.)
are stable releases. Releases with odd subversion numbers
(1.5, 1.7, etc.) are developmental versions and are available
only from the CVS repository. </P>
<P class=docText>At of the writing of this book, the current
stable release version is 1.6.5. The current developmental
version is 1.7.1. The changes presented here are currently
reflected in 1.7.1 and will probably remain relatively
unchanged in the next stable release梀ersion 1.8. </P><A
