<h2>Yap-5.1.0:</h2>

<li> NEW: debugger will not backtrack over complete deterministic computations.</li>
|

<li> NEW: debugger can show CP stack.</li>
|
||||
<li> NEW: internal procedure to show choice-point stack.</li>
|
||||
<li> FIXED: Incremental GC could still get confused after backtracking
|
||||
over GEN marker. Associate GEN marker with timestamp and make sure
|
||||
we only use current GEN markers (obs Mark Goadrich).</li>
|
||||
<li> FIXED: Yap on OSX should not make CreepFlag a register, as this
|
||||
breaks Interrupt Handling. Also, it seems that if I do not reserve
|
||||
r13, GCC will use r14 for its own evil purposes.</li>
