+ 0.89:

= fixes:

- load primitive-types in the target not the host
- test factor with compiz
- memory leak on os x
- ffi_test_18 on windows
- compiled call traces do not work if the runtime is built with
  -fomit-frame-pointer on ppc (and amd64?)
- cocoa: international keys don't work
- >bit-array doesn't work for tuples
- %allot-bignum-signed-1 doesn't work for zero or numbers which don't
  fit in 30 bits
- parsing word print demo doesn't work in ui listener
- error popup obscures input area
- poorly documented vocabs:
  - alien
  - cocoa
  - compiler
  - completion
  - image
  - interpreter
  - objc
  - optimizer
- crc32: unicode

= performance:

- do relative label relocations ahead of time
  - do we ever have absolute label relocations?
- float-mod intrinsic
- hashed generic dispatch
- if a loc appears multiple times on the phantom-stack, then we read
  it more than once as each occurrence is vreg-ified
- see if these are still Too Slow:
  - "factor.image" run-file  should fail quicker!
  - 10000 [ dup number>string ] map>hash describe in the UI
  - apropos
  - available-modules
  - md5, crc32
  - 100000 [ "\"hello\" not" eval drop ] times
  - compilation
  - make-image

= features:

- replace $see-also with a better system
- add full support for long longs to ffi
- double args in arm ffi
- integrate libs/unicode/
- single stepper: abadon feature which throws exception & continues
- overhaul parser
- variable width word wrap
- if we're printing a block on multiple lines, break at some words like
  set off on % # , ... and assembler opcodes
- don't end lines with literals, shuffle words or symbols?
- see should try to not show ; on a line by itself
- IN: on its own line if the entire 'see' form doesn't fit
- command buttons: indicate shortcuts
- how do we refer to command shortcuts in the docs?

+ 0.90:

= fixes:

- models: don't do redundant work
- auto-update browser and help when sources reload
- new windows don't always have focus, eg focus follows mouse
- should be possible to load multiple i/o backends, compiler backends,
  ui backends etc without problems

= performance:

- float arrays
- work on making spectral norm fast
- permgen
- inline allocators for constant size tuples and arrays
- no write barrier for stores of immediates
- more arm intrinsics: fixnum<>bignum conversions, (set-)char-slot,
  overflowing fixnum+ fixnum-, set-slot
- compiled continuations
- continue overflow check removal work: nappend
- memcspn is ugly, remove it and get a Factor inner loop to be as fast
- no need to generate dead code after a tail call
- why is every fp reg shadowed by an int reg?
- can def-use get the other case of fixnum-compare + conditional?
- >r >r fixnum< r> r> rot [ ... ] [ ... ] if -- use an if-intrinsic here
- cross-word type inference

= features:

- better tuple constructors
- case: support constant words
- new module system
- graphical crossref tool
- inspector where slot values can be changed
- some kind of declarative wiring framework for ui
- tuple shape changes
- UI unit test tool
- copying pane output
- right-click menu for words and links: show both word and link commands

+ 0.91:

= fixes:

- [ [ dup call ] dup call ] infer hangs
- fix conditions and restarts to work like CL
- amd64 structs-by-value bug
- float= doesn't consider nans equal
- clarify role of -0.0
- if a word drops the stack pointer below the bottom, then an error
  won't be thrown until the next word accesses the stack
- should be possible to reload any source file in library
- slice: if sequence or seq start is changed, abstraction violation
- callstack overflow when compiling mutually recursive inline words

= performance:

- see if its possible to only repaint dirty regions
- minor GC takes too long now, we should card mark code heap
- incremental GC
- prettyprinter: don't build entire tree to print first
- ui inspector should work with very large objects

= features:

- compiling 'curry'
- editor:
  - autoscroll
  - transpose char/word/line
  - more efficient multi-line inserts
- automatic help/effects for slot accessors

+ before 1.0:

- building minimal images
- cross compiling
- UDP
- factor should be an embeddable DLL
- profiler
- ipv6
- structure editor
