Changes in 1.5.5

• This is a pure bug-fix release that fixes runtime issues reported in 32-bit i386 builds, some of which would not affect a more common 64-bit architecture, but some of which could under the wrong circumstances, so this release should be used in preference to 1.5.4 or 1.5.3 on any architecture.

Other recent user-visible changes were announced in release 1.5.4 and release 1.5.3.

Please see the release notes for a more complete list of changes.
