174 =========================
176 ** Boehm garbage collector supported
177 ------------------------------------
179 The --enable-gc2 options was replaced by --with-gc. Choose boehm for the
180 Boehm garbage collector. Also see README.boehm.
185 Now runs on some SGI systems, which are based on the mips architecture.
187 ** multiple bug fixes
188 ---------------------
190 Even more java programs work as expected!
193 * Version 0.35 (experimental)
194 =============================
196 ** autoconf, automake support
197 -----------------------------
199 Finally moved the entire distribution to autoconf/automake. This should fix
200 some of our problems with supporting different compilers. Thread support and
201 the use of the new garbage collector can be enabled/disabled from using
204 --enable-threads [default]
207 --enable-gc2 [default]
210 ** new garbage collector
211 ------------------------
213 Included the new garbage collector as default garbage collector.
215 * Version 0.30 (released)
216 =========================
218 Added unlimited stack for GC and main thread.
219 Some optimzations for instructions which operate on constants.
221 * Version 0.20 (released)
222 =========================
224 Hardware null pointer check added, fixed severe errors in GC/Threads, type
225 check and IEEE arithmetic.
227 * Version 0.20beta (can't remember)
228 =========================
230 There is a completely new JIT compiler which is about 7 times faster and
231 produces better code.
232 Multithreading is now supported.
233 A lot of bugs have been fixed.
235 * Version 0.10 (ancient history)
238 The initial version included the old JIT and support for lang, util and io.
