94    [2017/08/12]::
95    +
96    Changed the way that we test for allocation-space addresses in minor GCs.
97    Instead of using the BIBOP, we now do a pointer range test.  On 32-bit
98    systems, this change results in a small (~0.13%) performance boost, but
99    we expect a bigger impact on 64-bit hardware, where the cost of BIBOP
100    probes will be higher and there are more registers available to hold
101    the nursery bounds.

107    +
108    Fixed some issues in build-literals.c.  These were mostly false
109    positives in the assertions, but there was also a bug in the way
110    that the available space was tracked that could conceivably
111    result in a crash (but was very unlikely).
