v0.15.1

Stabilise memory collection more

Reduce the tiny windows where objects aren't on the stack when they need
to be to avoid being GC'd.  There are still more, but this is stable
enough to run two threads of comettracer

v0.15.0

Improvements to the Hash class

Fixed a couple of spots where I was returning a C boolean instead of a
comet Boolean.

Added the has_key? method.

Implemented the Hash::contains? for iterable compatibility.

Actually started inheriting from 'Iterable'

v0.14.2

Initialise threads array to NULLs

If I'm going to rely on the array containing NULL values, then I should
probably write something into it.

v0.14.1

Made improvements to threading

Some memory issues sorted and you should be able to return a number from
a function without it segfaulting, now.

v0.14.0

Update tag github action

v0.13.0

Minor fixes

v0.12.0

Add min, max, and power to Number

v0.11.0

Undo generational GC implementation

The generational GC was problematic - we weren't re-marking anything
that made it from g0 into g1 so it wasn't working for us and would free
stuff that shouldn't have been free'd!

v0.10.0

Merge pull request #10 from cometlang/chore/speedup-math

Chore/speedup math

v0.9.0

Trim nanoseconds off operator call

Reorder things to be in a more likely manner and penalise the path with
the runtimeError the most, because performance at that point is not the
most important thing.
