122 =========================
124 ** Boehm garbage collector supported
125 ------------------------------------
127 The --enable-gc2 options was replaced by --with-gc. Choose boehm for the
128 Boehm garbage collector. Also see README.boehm.
133 Now runs on some SGI systems, which are based on the mips architecture.
135 ** multiple bug fixes
136 ---------------------
138 Even more java programs work as expected!
141 * Version 0.35 (experimental)
142 =============================
144 ** autoconf, automake support
145 -----------------------------
147 Finally moved the entire distribution to autoconf/automake. This should fix
148 some of our problems with supporting different compilers. Thread support and
149 the use of the new garbage collector can be enabled/disabled from using
152 --enable-threads [default]
155 --enable-gc2 [default]
158 ** new garbage collector
159 ------------------------
161 Included the new garbage collector as default garbage collector.
163 * Version 0.30 (released)
164 =========================
166 Added unlimited stack for GC and main thread.
167 Some optimzations for instructions which operate on constants.
169 * Version 0.20 (released)
170 =========================
172 Hardware null pointer check added, fixed severe errors in GC/Threads, type
173 check and IEEE arithmetic.
175 * Version 0.20beta (can't remember)
176 =========================
178 There is a completely new JIT compiler which is about 7 times faster and
179 produces better code.
180 Multithreading is now supported.
181 A lot of bugs have been fixed.
183 * Version 0.10 (ancient history)
186 The initial version included the old JIT and support for lang, util and io.
