135 =========================
137 ** Boehm garbage collector supported
138 ------------------------------------
140 The --enable-gc2 options was replaced by --with-gc. Choose boehm for the
141 Boehm garbage collector. Also see README.boehm.
146 Now runs on some SGI systems, which are based on the mips architecture.
148 ** multiple bug fixes
149 ---------------------
151 Even more java programs work as expected!
154 * Version 0.35 (experimental)
155 =============================
157 ** autoconf, automake support
158 -----------------------------
160 Finally moved the entire distribution to autoconf/automake. This should fix
161 some of our problems with supporting different compilers. Thread support and
162 the use of the new garbage collector can be enabled/disabled from using
165 --enable-threads [default]
168 --enable-gc2 [default]
171 ** new garbage collector
172 ------------------------
174 Included the new garbage collector as default garbage collector.
176 * Version 0.30 (released)
177 =========================
179 Added unlimited stack for GC and main thread.
180 Some optimzations for instructions which operate on constants.
182 * Version 0.20 (released)
183 =========================
185 Hardware null pointer check added, fixed severe errors in GC/Threads, type
186 check and IEEE arithmetic.
188 * Version 0.20beta (can't remember)
189 =========================
191 There is a completely new JIT compiler which is about 7 times faster and
192 produces better code.
193 Multithreading is now supported.
194 A lot of bugs have been fixed.
196 * Version 0.10 (ancient history)
199 The initial version included the old JIT and support for lang, util and io.
