126 * Version 0.40 (released)
127 =========================
129 ** Boehm garbage collector supported
130 ------------------------------------
132 The --enable-gc2 options was replaced by --with-gc. Choose boehm for the
133 Boehm garbage collector. Also see README.boehm.
138 Now runs on some SGI systems, which are based on the mips architecture.
140 ** multiple bug fixes
141 ---------------------
143 Even more java programs work as expected!
146 * Version 0.35 (experimental)
147 =============================
149 ** autoconf, automake support
150 -----------------------------
152 Finally moved the entire distribution to autoconf/automake. This should fix
153 some of our problems with supporting different compilers. Thread support and
154 the use of the new garbage collector can be enabled/disabled from using
157 --enable-threads [default]
160 --enable-gc2 [default]
163 ** new garbage collector
164 ------------------------
166 Included the new garbage collector as default garbage collector.
168 * Version 0.30 (released)
169 =========================
171 Added unlimited stack for GC and main thread.
172 Some optimzations for instructions which operate on constants.
174 * Version 0.20 (released)
175 =========================
177 Hardware null pointer check added, fixed severe errors in GC/Threads, type
178 check and IEEE arithmetic.
180 * Version 0.20beta (can't remember)
181 =========================
183 There is a completely new JIT compiler which is about 7 times faster and
184 produces better code.
185 Multithreading is now supported.
186 A lot of bugs have been fixed.
188 * Version 0.10 (ancient history)
191 The initial version included the old JIT and support for lang, util and io.
