Release Notes for Version 3.11

A collections library introduces hash maps, hash sets, sorted sets, queues,
and B-tree maps (which maintain sorted order) as templated modules,
along with iterator utilities such as zip and enumerate.
User-defined structs can now be iterated with range-based for loops
via operator iter, support bracket indexing through operator[] and
operator[=], and benefit from native hashing of ints, strings, reals,
and int arrays.  
The legacy getopt fallback was removed.
Rendering issues were addressed.
The documentation was reorganized.
