177 =========================
179 ** Boehm garbage collector supported
180 ------------------------------------
182 The --enable-gc2 options was replaced by --with-gc. Choose boehm for the
183 Boehm garbage collector. Also see README.boehm.
188 Now runs on some SGI systems, which are based on the mips architecture.
190 ** multiple bug fixes

193 Even more java programs work as expected!
196 * Version 0.35 (experimental)

200 -----------------------------
202 Finally moved the entire distribution to autoconf/automake. This should fix
203 some of our problems with supporting different compilers. Thread support and
204 the use of the new garbage collector can be enabled/disabled from using
207 --enable-threads [default]
210 --enable-gc2 [default]
213 ** new garbage collector
214 ------------------------
216 Included the new garbage collector as default garbage collector.
218 * Version 0.30 (released)
219 =========================
221 Added unlimited stack for GC and main thread.
222 Some optimzations for instructions which operate on constants.
224 * Version 0.20 (released)
225 =========================
227 Hardware null pointer check added, fixed severe errors in GC/Threads, type
228 check and IEEE arithmetic.
230 * Version 0.20beta (can't remember)
231 =========================
233 There is a completely new JIT compiler which is about 7 times faster and
234 produces better code.
235 Multithreading is now supported.
236 A lot of bugs have been fixed.
238 * Version 0.10 (ancient history)
241 The initial version included the old JIT and support for lang, util and io.
