186 ** Boehm garbage collector supported
187 ------------------------------------
189 The --enable-gc2 options was replaced by --with-gc. Choose boehm for the
190 Boehm garbage collector. Also see README.boehm.
195 Now runs on some SGI systems, which are based on the mips architecture.

200 Even more java programs work as expected!
203 * Version 0.35 (experimental)

207 -----------------------------
209 Finally moved the entire distribution to autoconf/automake. This should fix
210 some of our problems with supporting different compilers. Thread support and
211 the use of the new garbage collector can be enabled/disabled from using
214 --enable-threads [default]
217 --enable-gc2 [default]
220 ** new garbage collector
221 ------------------------
223 Included the new garbage collector as default garbage collector.
225 * Version 0.30 (released)
226 =========================
228 Added unlimited stack for GC and main thread.
229 Some optimzations for instructions which operate on constants.
231 * Version 0.20 (released)
232 =========================
234 Hardware null pointer check added, fixed severe errors in GC/Threads, type
235 check and IEEE arithmetic.
237 * Version 0.20beta (can't remember)
238 =========================
240 There is a completely new JIT compiler which is about 7 times faster and
241 produces better code.
242 Multithreading is now supported.
243 A lot of bugs have been fixed.
245 * Version 0.10 (ancient history)
248 The initial version included the old JIT and support for lang, util and io.
