149 =========================
151 ** Boehm garbage collector supported
152 ------------------------------------
154 The --enable-gc2 options was replaced by --with-gc. Choose boehm for the
155 Boehm garbage collector. Also see README.boehm.
160 Now runs on some SGI systems, which are based on the mips architecture.
162 ** multiple bug fixes
163 ---------------------
165 Even more java programs work as expected!
168 * Version 0.35 (experimental)
169 =============================
171 ** autoconf, automake support
172 -----------------------------
174 Finally moved the entire distribution to autoconf/automake. This should fix
175 some of our problems with supporting different compilers. Thread support and
176 the use of the new garbage collector can be enabled/disabled from using
179 --enable-threads [default]
182 --enable-gc2 [default]
185 ** new garbage collector
186 ------------------------
188 Included the new garbage collector as default garbage collector.
190 * Version 0.30 (released)
191 =========================
193 Added unlimited stack for GC and main thread.
194 Some optimzations for instructions which operate on constants.
196 * Version 0.20 (released)
197 =========================
199 Hardware null pointer check added, fixed severe errors in GC/Threads, type
200 check and IEEE arithmetic.
202 * Version 0.20beta (can't remember)
203 =========================
205 There is a completely new JIT compiler which is about 7 times faster and
206 produces better code.
207 Multithreading is now supported.
208 A lot of bugs have been fixed.
210 * Version 0.10 (ancient history)
213 The initial version included the old JIT and support for lang, util and io.
