148 =========================
150 ** Boehm garbage collector supported
151 ------------------------------------
153 The --enable-gc2 options was replaced by --with-gc. Choose boehm for the
154 Boehm garbage collector. Also see README.boehm.
159 Now runs on some SGI systems, which are based on the mips architecture.
161 ** multiple bug fixes
162 ---------------------
164 Even more java programs work as expected!
167 * Version 0.35 (experimental)
168 =============================
170 ** autoconf, automake support
171 -----------------------------
173 Finally moved the entire distribution to autoconf/automake. This should fix
174 some of our problems with supporting different compilers. Thread support and
175 the use of the new garbage collector can be enabled/disabled from using
178 --enable-threads [default]
181 --enable-gc2 [default]
184 ** new garbage collector
185 ------------------------
187 Included the new garbage collector as default garbage collector.
189 * Version 0.30 (released)
190 =========================
192 Added unlimited stack for GC and main thread.
193 Some optimzations for instructions which operate on constants.
195 * Version 0.20 (released)
196 =========================
198 Hardware null pointer check added, fixed severe errors in GC/Threads, type
199 check and IEEE arithmetic.
201 * Version 0.20beta (can't remember)
202 =========================
204 There is a completely new JIT compiler which is about 7 times faster and
205 produces better code.
206 Multithreading is now supported.
207 A lot of bugs have been fixed.
209 * Version 0.10 (ancient history)
212 The initial version included the old JIT and support for lang, util and io.
