v0.1   10/05/2005

Parsing of atoms

intial Tree printout

extraction of all "covr.data" atoms out
to files

v0.2   11/10/2005

AtomicInfo.NextAtomNumber introduced to facilitate dynamic atom tree
reorganization

CreateSparseAtom added

v0.5   11/22/2005

Writes artist properly of variable lengths properly into an iTMS m4p file
properly (other files don't fare well due to the stsd atom non-standard
nature)

a number of code-uglifying workarounds were employed to get get that
far;

v0.6   11/25/2005

Added genre string/numerical support, support for genre's dual-atom ©gen/gnre
nature, genre string->integer

bug fixes to APar_LocateAtomInsertionPoint when
an atom is missing

APar_CreateSparseAtom for ordinary non-data atoms are now
type -1 (which means they aren't of any interest to us besides length & name);
implemnted the Integer data class

char4short

verified iTunes standard genres
only go up to "Hard Rock"

added jpg/png artwork embedding into "covr" atoms;
slight bugfix for APar_FindAtom (created spurious trailing "covr" atoms).

v0.6    GPL'ed at sourceforge.net

v0.65   11/25/2005

bugfixes to newly introduced bugs in APar_FindAtom

metaEnema to remove all
metadata (safe even for m4p drm files)

year implemented properly (tagtime
moved onto non-standard 'tdtg' atom ala id3v2.4 - because I like that tag);
added setting compilation "cpil" tag (an annoying 5byte tag)

added advisory
setting (maybe it'll give me a kick one cold winter day-do a "Get Info" in
iTunes & in the main "Summary" tab view will be a new little icon next to
artwork)

v0.7    11/26/2005

added a writeBack flag to for a less beta-like future

integrated NSImage
resizing of artwork

environmental preferences for artwork modifications

build
system mods for Mac-specific compiling



v0.7.1  11/27/2005 

modified parsing & writing to support Apple Lossless (alac) mp4 files. The
lovely "alac.alac" non-standard atoms (parents & carry data) caused unplayable
files to be written. Only QT ISMA files get screwed now (no idea about Nero)

v0.7.2  11/29/2005 

creates iTunes-required meta.hdlr

all the tags now get spit back when reading
them (--textdata)

slight fix to how atoms are parsed

all known m4a files now
tag properly: iTunes (m4a, m4b, chapterized, alac), Quicktime (ISMA & mpeg4 -
change filename ext to .m4a to see art

all QT products require the meta.hdlr
addition), faac, Helix Producer & Nero

slight change to how PrintDataAtoms
called FindParentAtom

added tag time on "©ed1" (edit date-might only really
belong directly under udta)

added "©url" to hold url

fixes to
APar_RemoveAtom

added cli ability to remove all artwork

v0.7.3  12/02/2005 

handles stsd (and child) atoms better

modifies all stco offsets when needed
(not just the first)

new oddball iTMS video "drmi" atom handling

new "stik"
atom support (sets iTunes GetInfo->options:Movie,TV Show, Music Video)

writes
iTMS video drm TV shows well now

diffs in a hex editor are moov atom length,
and then into stco, so all is well

v0.7.4  12/03/2005

"desc", "tvnn", "tvsh", "tven" & "tves" setting

v0.7.5b 12/09/2005

forced 'mdat' into being childless (chapterized mpeg4 files have atoms
scattered througout mdat, but they aren't children)

fixed issues with ffmpeg
created mpeg4 files (that have mdat as 2nd atom

moov & chilren as last atoms);
moved ffmpeg mdat atoms around to end

better atom adding at the end

subbed
getopt_long_only to getopt_long for pre-10.4 users

added progressbar

v0.7.5c 12/10/2005

funnguy0's linux patches (thanks so much for that)

v0.7.5d 12/11/2005

endian issues for x86 mostly resolved

setting genre's segfaults

stik doesn't
get set in a multi-option command, but does as a single atom setting

Debian
port added to binaries (compiled under debian-31r0a-i386 with g++4.02-2,
libc6_2.3.5-8 & libstdc++6_4.0.2-2) - under VirtualPC - with the nano editor!

v0.7.5e 12/16/2005

ammends how atoms are added at the end of the hierarchy (notably this affects
ffmpeg video files)

writes "keyw", "catg", "pcst", "aART" atoms

read-only
"purl" & "egid" added

v0.7.6  12/31/2005

ceased flawed null-termination (which was implemented more in my mind) of text
'data' atoms

UTF-8 output on Mac OS X & Linux - comment in DUSE_ICONV_CONVERSION in the
build file to test it other platforms (maybe my win98Se isn't utf8 aware?)

cygwin build accommodations

fix to the secondary "of" number for track/disk on non-PPC

implemented user-defined completely sanctioned 'uuid' atoms to hold....
anything (text only for now)

"--tagtime", "--url" & "--information" now get set onto uuid atoms

allow creation of uuid atoms directly from the cli

cygwin-win98SE port added to binary releases

added '--freefree' to remove any&all 'free' atoms

v0.8    01/14/2006

switched over to uint8_t for former ADC_CPIL_TMPO & former ADC_Integer

added podcast stik setting & purl/egid

bugfixes to APar_RemoveAtom

bugfixes & optimizations to APar_FindAtom

changes to text output & set values for stik atom

increase in buffer size

limit non-uuid strings to 255bytes

fixed retreats in progress bar

added purd atom

support mdat.length=0 atom (length=1/64-bit isn't supported

I'll somehow cope with a < 4GB file)

switch from long to uint32_t
  
better x86 bitshifting

added swtich to prevent moving mdat atoms (possible PSP requires mdat before
moov)

universal binary for Mac OS X release

no text limit on lyrics tag

v0.8.4  02/25/2006

fixed an imaging bug from preferences

fixed metaEnema screwing up the meta atom (APar_RemoveAtom bugfix to remove a
direct_find atom)

added --output, --overWrite

added --metaDump to dump ONLY metadata tags to a file

versioning for cvs builds

limited support for 64-bit mdat atoms (limited to a little less than a 32-bit
atom > 4GB)

bugfixes to APar_RemoveAtom for removing uuid atoms or non-existing atoms & to
delete all artwork, then add in 1 command ("--artwork REMOVE_ALL --artwork
/path --artwork /path")

support 64-bit co64 atom

support MacOSX-style type/creator codes for tempfiles that end in ".mp4" (no
need to change extn to ".m4v"/".m4a" anymore)

moved purl/egid onto AtomicDataClass_UInteger (0x00 instead of 0x15) to mirror
Apple's change on these tags

start incorporating Brian's Win32 fixes (if you malloc, memset is sure to
follow fopen)

give the 'name' atom for '---' iTunes-internal tags for metadata printouts

allow --freefree remove 'free's up to a certain level (preserves iTunes
padding)

squash some memory leaks

change how CreateSparseAtom was matching atoms to accommodate EliminateAtom-ed
atoms (facilitates the previous artwork amendments)

exit on unsupported 'ftyp' file brands

anonymous 3rd party native win32 contributions

reworked APar_DetermineAtomLengths to accommodate proper tag setting with
--mdatLock

parsing atoms under 'stsd' is no longer internally used - only for tree

bytes in win98 & earlier

memset standard means of initializing

libiconv

properly display atoms like '©nam' under Windows for trees & atom printouts

support setting unicode on Windows CP_UTF8

added 3GP keyword

fixed bug removing last 3GP asset to reset the length of 'udta'

added 'manualAtomRemove' for manually removing iTunes-style atoms

improved tracking of filesize/percentage when large free atoms impinge on % of
new filesize

SLarew's utf16 fix for printing 3gp assets on Win32

details)

bashfulbladder's booklet stik, only allow dynamic updating with --overWrite &
new "AP -t +" routine to show padding & supplemental info

changing win32 filename to '-utf8.exe' forces raw utf8 input/output

win32 longhelp is converted to utf16 (for atom names)
