153 * Version 0.40 (released)
154 =========================
156 ** Boehm garbage collector supported
157 ------------------------------------
159 The --enable-gc2 options was replaced by --with-gc. Choose boehm for the
160 Boehm garbage collector. Also see README.boehm.
165 Now runs on some SGI systems, which are based on the mips architecture.
167 ** multiple bug fixes
168 ---------------------
170 Even more java programs work as expected!
173 * Version 0.35 (experimental)
174 =============================
176 ** autoconf, automake support
177 -----------------------------
179 Finally moved the entire distribution to autoconf/automake. This should fix
180 some of our problems with supporting different compilers. Thread support and
181 the use of the new garbage collector can be enabled/disabled from using
184 --enable-threads [default]
187 --enable-gc2 [default]
190 ** new garbage collector
191 ------------------------
193 Included the new garbage collector as default garbage collector.
195 * Version 0.30 (released)
196 =========================
198 Added unlimited stack for GC and main thread.
199 Some optimzations for instructions which operate on constants.
201 * Version 0.20 (released)
202 =========================
204 Hardware null pointer check added, fixed severe errors in GC/Threads, type
205 check and IEEE arithmetic.
207 * Version 0.20beta (can't remember)
208 =========================
210 There is a completely new JIT compiler which is about 7 times faster and
211 produces better code.
212 Multithreading is now supported.
213 A lot of bugs have been fixed.
215 * Version 0.10 (ancient history)
218 The initial version included the old JIT and support for lang, util and io.
