Changes since the 1.9.1 release

Library updates (outstanding ones only)

Language changes

  • Regexp properties (p{}) names now ignore underscores, spaces, and case, so p{ol chiki} is the same as p{Ol_Chiki}

  • Regexps now support Unicode 5.2 (new characters and scripts)

  • d, s, and w are now ASCII only; use POSIX bracket classes and p{} for Unicode semantics

  • $: no longer includes the current directory, use require_relative

  • Symbol with an invalid encoding is forbidden to exist.

Compilation options

  • –program-prefix and –program-suffix no longer act on the shared object names nor paths to libraries.

    use –with-rubylibprefix='${libruby}/${RUBY_INSTALL_NAME}' and –with-soname='${RUBY_INSTALL_NAME}' for the same result as Ruby 1.9.1.

  • –with-arch is added for universal binary, instead of –enable-fat-binary option.
