The History of PowerData
This file contains descriptions of the specific changes and fixes that
occur in the different releases of PowerData. The most recent version is
first in the list.
The following list of abbreviations indicate the nature of the change:
MIN - Minor bug fixed
MAJ - Major bug fixed
NEW - New feature
CH - Change in operation
OPT - Optimization or improvement of existing feature
-----------------------------------------------------------------------------
PowerData 38.210 - Unintentional V39 dependency in 38.200 removed
23-Aug-1993 MAJ Due to a small oversigt on my part, 38.200 was
actually 3.0-only. This manifested itself by oceans
of Enforcer hits and wrong gadget settings in the
main window, when this was opened. Fixed.
NEW Swedish (svenska) translation graciously provided
by Jonny Lundin
MIN Files were not always being crunched, even when
matching the filters. Fixed.
CH 'Save' gadget now closes the window (like 'Use').
OPT Gadget hotkey routine optimized, redundant code
removed.
NEW Added some built-in logic to automatically preclude
certain special files as well as most archive formats
from being crunched and/or decrunched. The filter is
currently set to:
#?.(lha|lzh|zip|zoo|arc|jpg|jpeg|arj|dms) and
(#?startup-sequence)|(#?user-startup)|(#?PowerData.info)
Please read the docs for a more detailed explanation
of this.
MIN PowerData did not close the catalog it was using.
This made it very difficult to make new language
translations for PowerData, since you had to reboot
the machine to test a modified string. Fixed.
CH Now uses keyfiles for registration.
OPT Additional visual improvements:
· More attractive gadget hotkey underscoring
· No more double-refresh when zipping the window
(thanks to Magnus 'ReqChange' Holmgren (2:204/404.6)
for his help and advice :-)
OPT Recompiled with SAS/C 6.3. This shaved an impressive
5032 bytes off the executable, and also made it much
faster. Bye bye, Aztec... :-)
NEW Dutch (nederlands) translation graciously provided
by Paul van der Heu
-----------------------------------------------------------------------------
PowerData 38.200 - Intermediate version before MAJOR new release
24-Jul-1993 CH ARexx interface is now compulsory. In stead of the
previous non-arexx executable you now get a special
68020+ version (popular request)
OPT Localizing code cleaned up and optimized
OPT Miscellaneous GUI improvements, including
· Backfilled window
· Scalable checkbox gadgets (V39)
· New-style menus (V39)
· Hotkey shortcuts for gadgets
MIN GUI Bevelboxes were not being refreshed during window
zoom operations. Fixed.
NEW Busypointer during crunch/decrunch is now switchable
via a new checkbox gadget in the main window
CH Distribution now includes reqtools 38.1042
NEW Filenames are now expanded to include paths before
being submitted to pattern matching. This allows you
to use filters like "DH0{80MB}:Somedir/#?/s/#?.pp".
You can still use the old "filenames-only" method
via a checkbox gadget in the main window. The old
method was retained because it is faster.
NEW Decrunching can now be made to work for files that do
NOT match the patterns. This allows applications to
always read crunched files, but only have those files
crunched that do match the patterns
NEW Now also patches OpenFromLock() to provide more
complete Powerpacker support. May cure many problems
with software failing to read Powerpacked files even
with PowerData running.
CH ARexx port name changed to POWERDATA. Please fix
whatever ARexx scripts you have.
CH Default temporary directory changed from POWERDATA_T:
to just T:
NEW Distribution now includes full CatComp source
NEW New icon for the PowerData executable. Hope you like
it :-)
-----------------------------------------------------------------------------
PowerData 38.115 - Basic ARexx interface, more bugs squashed
09-Mar-1993 MAJ/MIN Several bugs of different nature were found in the
previous version. Hopefully I got them all now.
NEW ARexx interface, finally! There are currently seven
commands, doing everything from quitting PowerData,
to making it show its window.
NEW The installation scripts now ask which version of
PowerData you wish to install (Rexx, or non-Rexx).
CH New reqtools.library once again. This time v38.1022.
NEW Italian localization [Mirco Zanca]
NEW Windows are locked and made to display a wait pointer
(clock image) when PowerData is either crunching
or decrunching data.
-----------------------------------------------------------------------------
PowerData 38.110 - Global crunch/decrunch switches, new prefs file format
08-Feb-1993 NEW Global switches enabling and disabling transparent
crunching and/or decrunching.
NEW/CH PowerData now reports if its prefs file is mangled
when it starts up (a small bug, really :-)
CH Prefs file format changed, allowing for more
complex filename patterns and other, future
enhancements.
MIN Changed default hotkeys from "ctrl alt ..." to
"control alt ...". Commodities.library v37 only
understands the latter format [Finn Kettner]
CH PowerData now comes with v38.1020 of
reqtools.library. This version is a bit newer than
the library contained in the 38.105 distribution.
MAJ Pattern handling was not entirely consistant. An
internal buffer was set to hold patterns of 30
characters, even though patterns span much more
than that. This problem caused spurious gurus to
appear when editing the pattern gadgets.
NEW Installer script now fully localized in French
[Reza Elghazi]
-----------------------------------------------------------------------------
PowerData 38.105 - Mostly bug fixes
17-Jan-1993 MAJ PowerData *required* locale.library to be present
in order to work at all. Fixed.
MIN The evaluation version of PowerData would hang if
it could not open any one of the required libraries.
-----------------------------------------------------------------------------
PowerData 38.100 - First public release. Hope you like it!
07-Jan-1993 NEW Added French localization file (Reza Elghazi)
CH Updated installation scripts accordingly
NEW Added German localization file (Norbert Fährmann)
CH Updated installation scripts accordingly
