199 The --enable-gc2 options was replaced by --with-gc. Choose boehm for the
200 Boehm garbage collector. Also see README.boehm.

221 the use of the new garbage collector can be enabled/disabled from using
224 --enable-threads [default]
227 --enable-gc2 [default]

244 Hardware null pointer check added, fixed severe errors in GC/Threads, type
245 check and IEEE arithmetic.
247 * Version 0.20beta (can't remember)
248 =========================
250 There is a completely new JIT compiler which is about 7 times faster and
251 produces better code.
252 Multithreading is now supported.
253 A lot of bugs have been fixed.
255 * Version 0.10 (ancient history)
258 The initial version included the old JIT and support for lang, util and io.
