146 * Version 0.40 (released)
147 =========================
149 ** Boehm garbage collector supported
150 ------------------------------------
152 The --enable-gc2 options was replaced by --with-gc. Choose boehm for the
153 Boehm garbage collector. Also see README.boehm.
158 Now runs on some SGI systems, which are based on the mips architecture.
160 ** multiple bug fixes
161 ---------------------
163 Even more java programs work as expected!
166 * Version 0.35 (experimental)
167 =============================
169 ** autoconf, automake support
170 -----------------------------
172 Finally moved the entire distribution to autoconf/automake. This should fix
173 some of our problems with supporting different compilers. Thread support and
174 the use of the new garbage collector can be enabled/disabled from using
177 --enable-threads [default]
180 --enable-gc2 [default]
183 ** new garbage collector
184 ------------------------
186 Included the new garbage collector as default garbage collector.
188 * Version 0.30 (released)
189 =========================
191 Added unlimited stack for GC and main thread.
192 Some optimzations for instructions which operate on constants.
194 * Version 0.20 (released)
195 =========================
197 Hardware null pointer check added, fixed severe errors in GC/Threads, type
198 check and IEEE arithmetic.
200 * Version 0.20beta (can't remember)
201 =========================
203 There is a completely new JIT compiler which is about 7 times faster and
204 produces better code.
205 Multithreading is now supported.
206 A lot of bugs have been fixed.
208 * Version 0.10 (ancient history)
211 The initial version included the old JIT and support for lang, util and io.
