Details of recent upgrades:

=============================================================================
240 (30th July 2000)
	**MASSIVE REWRITE AND BUG-FIX**
	Finally replaced DrWimp routines with my own WIMP handling.
	Fixed many bugs.
	Added supported for Choices directory in new !Boot sequence.
	Tinkered yet again with interactive help and error-trapping.

240 (1st August 2000)
	Fixed newly-introduced bug causing a crash during zipping if *none* of the entries in the zip options menu were ticked.

241 (4th August 2000)
	Fixed bug introduced by above bug-fix....
	Remove 'Load file on double-click' option from zip options menu.   This option is now always on.
	Implemented version-independent Config file reading to make future changes to format invisible to the user.
	Tinkered - again - with interactive help and error-trapping.
	The configurable value for the alert box display time is now set to 0 (close as soon as possible) if you leave it blank.
	Fixed bug causing Infozip to close files that didn't belong to it.
	Titlebar of savebox now highlighted when it claims input focus.

242 (12th September 2000)
	Fixed bug in machine code which occasionally caused Infozip to miss files.

243 (29th September 2000)
	Replaced DOS filename format option (8 characters + "/zip") with Unix filename format (lowercase + "/zip" on the grounds that this can be used for both;  saving files to DOS disc automatically truncates the first part of the names and converts it to uppercase anyway....
	Changed menu option 'Overwrite silently' to 'Only extract newer' (-u command line option instead of -o) to provide more consistent behaviour irrespective of whether you were decompressing from the root directory of the archive or not - see Readme file for a description.   Now possible to force overwriting with older versions (i.e. restoring backups) as well as to prevent it.

244 (25th October 2000)
	Added 'Zip images as single files' option.
	Yet more error trapping on configuration file handling.

=============================================================================
250 (5th January 2001)
	Infozip can now save zipfiles into applications (e.g. to be used as email attachments) via a scrap file.
	ADJUST-clicking on the Close icon of an Infozip window under certain circumstances no longer causes a crash.
	Pressing RETURN in the savebox actually works.
	Added text-format History file!
	Filer-like behaviour when dragging a selection of files had been accidentally reversed.   Now restored to normal ('package' icon for RISC-OS 35+ and greater/rotating dash-box for RISC OS 31).
	Fixed conversion to self-extracting archives of zipfiles /not/ ending in '/zip' (accidentally broken back in version 240!)
	Upgraded to use the latest versions of the Info-ZIP routines.
	*Moving* files (i.e. deleting the originals after zipping them) into anything other than the top level directory of a zip archive has never worked properly. Patched this.

=============================================================================
260 (3rd March 2001 - Chris Bazley)
	Fixed the ARM code so that it works with 'new style' LF+CR instead of 'old' CR+LF redirected command-line output.
	Overhauled the behaviour and appearance of the Configure window to be more style-guide compliant. The configuration is now properly stored in the program, rather than simply being read from the icons. This allowed a Cancel button to be implemented.
	Implemented some new short-cuts: f1 to open the manual, and Escape/OK for controlling dialogue windows. ADJUST-click on Infozip icon now opens configure dialogue.
	Fixed a bizarre bug where some icons were draggable, when they certainly should not have been!
	Rearranged the pop-up menu to be consistent with the RISC OS Filer, as far as possible. "Zip options >" from the iconbar menu has been superseded by the improved configure dialogue.
	Now adds the Info-ZIP routines to <Run$Path>, so that people can also use them from the command line if they choose.
	Included new hi-res icon by Nick Wright (nick@backtoreality.freeserve.co.uk)

261 (4th March 2001 - C.B.)
	Fixed the ARM code to be neutral about line-terminators in the zipfile catalogue, since this seems to be completely arbitrary. Thanks to T.Atherton for lending me his computer so that I could fix this.

262 (5th March 2001 - C.B.)
	Fixed tiny bug with interactive help.

263a-d (6-16th March 2001)
	Restoration of catalogue-scanning code lost in the transition to v260 continues.
	Increased wimpslot from 48k to 52k.
	In the grand Infozip tradition, added more error-trapping.

264 (15th May 2001 - C.B.)
	Redesigned 'Save As' dialogue with Cancel and Save buttons rather than having a close icon.
	The Configure dialogue is now more proficient at regaining the input focus.
	Fixed end-of-buffer checking bug in the window templates loader.
	Removed ancient history from StrongHelp manual.

2.65 (27th May 2001 - C.B.)
	Zipfile catalogue now displays files as untyped rather than 'Data', to avoid anyone thinking that they actually were.
	Pointer now changes to hourglass when moved over Infozip windows, and we are busy. 
	'Save as' dialogues now pop-up above the Infozip icon (like the application menu) rather than on top of it. 
	Changed the file info window to use standard icons for the text fields.
	No longer gives silly error when its own file icons are dragged within the window of origin.

=============================================================================
3.00 (October 2001)
	**MASSIVE REWRITE AND BUG-FIX!**
	Totally rewrote graphical representation of catalogue data.   'Internal path' in DOS format is now displayed in separate pane at top of Contents window - titlebar displays path of actual zipfile (more useful for Director menus and more sensible as editor-like behaviour).   An 'up' icon on the pane is now used to go up to previous contents level (in addition to existing menu options) - ADJUST-click on the window's Close icon will open the parent directory of the zipfile itself.   The 'up' icon is greyed out when the display already shows the topmost level of the zipfile.
	There is no longer an arbitrary limit on the number of files that can be displayed in any one directory.   The distance between neighbouring columns of icons is adjusted, RiscPC-style, according to icon width - long filenames are no longer unreadable.
	Icons in window now rearrange vertically when window is resized - and window can no longer be created wider than the current screen mode!   Hence removed horizontal scroll bar again.
	Icon widths are now properly calculated (for current font) in the catalogue window, and if necessary then long filenames are cropped with ""
	Width of Iconbar icon properly calculated for current font.
	Resizes Iconbar and catalogue window text on mode/font change.
	The initial width of a Contents window is always sufficient to display the full 'internal path' for that level.   If the width is reduced manually, the text in the icon will be right-aligned so that the most important data continues to show.
	The path shown in the File info window is also right-aligned if too long to fit in the icon.
	Added 'Name order' option, in addition to old default 'Archive order' behaviour, and provided Display submenu to toggle between them.
	Updated alertbox window template to cope with longer messages.
	Infozip will now load zipfiles even when an image filing system that claims this filetype (i.e. SparkFS, ArcFS 2) is running, provided they are explicitly dragged to the iconbar.   [James Lampard]
	Added MPEG filetype &1AD to list of pre-compressed types to ignore
	Substituted 'Idle' for 'Zip' as iconbar text when taskwindow is not running, to avoid confusion when *un*zipping is what is desired.
	SHIFT-SELECT on iconbar now opens Configure dialogue, ADJUST opens 'New archive' savebox.
	Tidy-up of menu handling - entries are now correctly greyed/ungreyed as applicable when Contents window menu is kept open using ADJUST.
	The Contents window menu now distinguishes between applications and directories, instead of labelling both simply as 'Dir'.
	All filetypes are now padded out to three digits with leading zeroes before checking against the string <Infozip$DontCompress> so that certain 'user' filetypes (in the range &001 to &0FF) are no longer incorrectly identified as compressed.
	Alertbox and configure windows now vertically centred on screen - width of window was being used instead of height!
	The default name used when creating a new zipfile is now taken from the Messages file (token Sname:) and suffixed by "/zip" if the 'Unix format zipfile names' option is set.
	Added new-style archive sprites for RISC OS 4 [NoMercy]

301 (28th November 2001)
	Untyped files are now compressed when dragged to the contents window as well as to the iconbar.
	Removed pane-handling bug - the contents window now iconises and comes to the front correctly.
	Added option to allow the pane to be configured off - in which case ADJUST-click on close icon reverts to old behaviour
	Program once again saves choices inside application directory if Choices$Write not defined, and reads from Choices$Path rather than Choices$Write!
	Rudimentary debugging log option added - if the program is started with a "-debug" switch, all Info-ZIP commands will be written out to <Infozip$debugfile>.

302 (14th January 2002)
	Corrected bug in WIMP message handling that could corrupt very long leaf-names, resulting in bizarre errors.
	Corrected bug causing Infozip window to come to front on mode change.

303 (23rd January 2002)
	Supplied missing help token in Messages file
	Main window is once again redrawn correctly when internal path pane is toggled on/off.

303b (3rd February 2002) *sigh*....
	output filename is now enclosed in quotes, to catch cases where it contains a space
	Patched file info window handling to ensure exact matching of strings, instead of merely matching the first filename which *ends* with the right string.

304 (26th June 2002 - C.B.)
	Fixed non-redraw of file icons in zipfile contents window, where the window was less than one column's width wide.
	Reads config file from Choices$Path rather than Choices$Write (don't know why this was claimed previously as fixed).
	Defines name of &DDC filetype as 'Archive' (in line with SparkPlug).
	Internationalised resources structure (uses ResFind).
	'Busy' message now more discrete (uses the alert box), rather than a nasty big Wimp error box.
	Drags terminating at path pane now treated as analogous to drags into zipfile contents window.

305 (19th January 2003 - C.B.)
	Fixed bug where zipfile window was re-opened too tall after toggle size icon had been clicked.
	Width of path pane now correctly varies with width of zipfile window.
	The included version of the SlidingHeap module is now 32-bit compatible, as are the back-end programs. The whole application should now work on Iyonix.
	Moved 'Help' option to top of iconbar menu, in line with latest advice from Castle Technology.
	Converting zipfiles to self-extracting archives no longer invokes 'Join' program (which conflicted with GNU Join).
