175 =========================
177 ** Boehm garbage collector supported
178 ------------------------------------
180 The --enable-gc2 options was replaced by --with-gc. Choose boehm for the
181 Boehm garbage collector. Also see README.boehm.
186 Now runs on some SGI systems, which are based on the mips architecture.
188 ** multiple bug fixes
189 ---------------------
191 Even more java programs work as expected!
194 * Version 0.35 (experimental)
195 =============================
197 ** autoconf, automake support
198 -----------------------------
200 Finally moved the entire distribution to autoconf/automake. This should fix
201 some of our problems with supporting different compilers. Thread support and
202 the use of the new garbage collector can be enabled/disabled from using
205 --enable-threads [default]
208 --enable-gc2 [default]
211 ** new garbage collector
212 ------------------------
214 Included the new garbage collector as default garbage collector.
216 * Version 0.30 (released)
217 =========================
219 Added unlimited stack for GC and main thread.
220 Some optimzations for instructions which operate on constants.
222 * Version 0.20 (released)
223 =========================
225 Hardware null pointer check added, fixed severe errors in GC/Threads, type
226 check and IEEE arithmetic.
228 * Version 0.20beta (can't remember)
229 =========================
231 There is a completely new JIT compiler which is about 7 times faster and
232 produces better code.
233 Multithreading is now supported.
234 A lot of bugs have been fixed.
236 * Version 0.10 (ancient history)
239 The initial version included the old JIT and support for lang, util and io.
