- Implementation
++ Implemented bytecode annotations
++ Role composition is now aware of multi-subs
++ Unbuffered IO PMCs now autopromote when buffering is necessary
++ Installation parrot binary and libparrot shared library now supported
++ Class registry now respects HLLs
- Compilers
++ IMCC
--- removed keyed string indexing, e.g. $S0[1].
--- removed slice syntax, e.g. $P0[1..2]
--- removed .namespace /.endnamespace pair
--- fixed 'new $P0, [classname]' syntax
++ PIRC
--- refactoring of various data structures
--- various bug fixes and updates
--- complete bytecode generation
--- add '-x' commandline option to run compiled code
++ PCT
--- add 'hll' and 'subid' attributes to PAST::Block
--- refactor loop handling code to handle last/redo/next
--- add :pasttype('stmts') and :pasttype('null')
--- improve "scope not found" error message
--- allow PAST::Val nodes to contain block references
++ PGE
--- add "skipkey" option to PGE::OPTable
--- allow spaces before modifiers in regexes
--- add '(' ~ ')' goal matching syntax
--- skip creating a class/grammar if it already exists
--- Languages
++ Rakudo
--- improved error mesages in multi dispatch
--- implemented clone method for all objects
--- implemented MAIN sub
--- Unicode versions of infix hyper operators
--- refactored IO.readline
--- basic support for Inf and NaN
--- list and array slices with whatever star
--- hash slices
--- implemented last and redo
--- pointy blocks as terms
--- refactored variable and parameter passing
--- improved assignment semantics
--- improved parsing of type names and subs
--- mostly implemented parametric roles
--- separate types for blocks, subs and methods
--- basic support for submethods
--- implemented Junction autothreading of user code (not builtins yet)
--- eval supports :lang attribute
--- proto makes other subs in scope multis, including in role composition
++ Befunge
--- back to working state
--- ported to pir
++ Pipp
--- add support for predefined constant __CLASS__ and __METHOD__
--- add initial support for static members
--- add support for namespaced constants
--- constants are now handled as package vars
--- variables are now lexical variables
--- add support for superglobals in functions
--- Call the class __constructor when there is one
--- added incomplete support for closures
--- removed support for the alternative parsing strategies
--- added support for 'elsif'
--- added support for 'do-while'
++ HQ9+
--- left the nest and is now at https://github.com/bschmalhofer/hq9plus/
++ Eclectus
--- left the nest and is now at http://github.com/bschmalhofer/eclectus/
++ m4
--- left the nest and is now at http://github.com/bschmalhofer/m4/
++ Lua:
--- add a minimalist user back trace
++ PIR
--- "does" and "morph" VTABLE interfaces are now overridable from PIR
--- Miscellaneous
++ Infrastructure
--- 'make smoke' now generates Smolder reports sent to http://smolder.plusthree.com/app/public_projects/smoke_reports/8
++ Improved const and null correctness for C function parameters
++ Sped up STRING manipulation (append, chop), improving PGE about 30%
++ BOOK
--- Added sections about Classes, OO programming, and methods.
--- Added information about Annotations, Exceptions, and Handlers
++ STM
--- Removed non-functional STM subsystem
