More informative syntax errors
The parser now posts the details of syntax errors, example:

123;
::

teletype::
ERROR: syntax error, unexpected BINOP, expecting ']'
in file 'selected text'

@section{subsection}
Remove old syntax
@racketblock[#(a:1):: was valid syntax, but yielded nonsense results. This will now result in a syntax error instead.

YAML/JSON parser
link::Classes/String#-parseYAML:: and link::Classes/String#-parseYAMLFile:: can be used to parse YAML or JSON.
@section{subsection}
SynthDef optimizations for additive terms
When the SynthDef is compiled, separate additive ugens are combined via the new link::Classes/Sum3:: and
link::Classes/Sum4:: ugens.
@section{subsection}
Basic dead code elimination for SynthDefs
The process of building synthdefs now performs a simple dead code elimination pass, which removes all
link::Classes/PureUGen:: instances without successor.
@section{subsection}
Case sensitive String comparison
String comparison operators (teletype::==, !=, <=, >=, >, <::) are now case sensitive.

SplayAz Bug Fix
Positioning of SplayAz was broken. The semantics of the TELETYPE::spread:: and TELETYPE::center:: arguments has
been changed in order to fix the behavior.
@section{subsection}
Array primitives respect mutability
The array primitives now respect object mutability: writing to an immutable object now fails and changing an
immutable object with TELETYPE::add::, TELETYPE::addAll::, TELETYPE::insert::, TELETYPE::extend::,
TELETYPE::growClear:: and TELETYPE::overwrite:: will return a newly allocated object.
