- [ This release note should accompany distribution of UpdateMaker 1.2 ]
-
- This is the third complete release of UpdateMaker and the first that I'm
- happy enough with to commit to final form. This is not a beta version and
- will not expire. 1.2b1, the previous version, will expire on or about the
- 22nd of March 1992, although it can still be used if you set your calendar
- back. Differences from 1.2b1 are summarised below - numerous bugs have been
- fixed and all users should switch to this version.
-
- UpdateMaker is a utility program for making and applying update documents,
- or for making stand-alone update applications.
-
- An update document or application describes the differences between any two
- Macintosh files and the changes required to convert one file into the other.
-
- It is often advantageous to distribute update documents rather than a
- completely new version of a file, not only because the update document
- tends to be smaller, but also because it is useless unless the old
- original file is available.
-
- Stand-alone update applications are some 11K larger than the equivalent
- document but have the advantage that the receiver does not need to have a copy
- of UpdateMaker to use them.
-
- UpdateMaker can create an update document for literally any two Macintosh
- files, be they applications, documents, system extensions, or whatever.
- For example, one can make an update document that will describe the differences
- between the Font/DA Mover application and Disk First Aid, and change one
- into the other.
-
- Documentation on how to use UpdateMaker is built into the Help menu of the
- application. No other manual is provided or required, because UpdateMaker
- uses the standard Macintosh interface conventions 8-).
-
- UpdateMaker requires System 6 or later; it is fully System 7 compatible and
- slightly System-7 friendly. It was written with MacApp The Wonder Development
- System, which is the main reason for its inordinate size.
-
- UpdateMaker is copyright 1992 Analog Digital Instruments Ltd and is made
- available to you by the Shareware principle: try it out and if you find
- it useful enough to keep and use it, we ask for a shareware payment
- (address details are in the Help documentation). For private use, we
- ask for a $10 shareware payment, for commercial use we ask for $50. Large
- companies or institutions should contact us about licensing.
-
- The author would be grateful for any bug reports or constructive suggestions
- not requiring the entire application to be rewritten :-).
-
-
- Differences from 1.2b1:
-
- Functional bugs (in approximate order of seriousness)
- - An uninitialised pointer bug caused crashes during the build specification when
- you clicked on Old File or New File.
- - Some updates crashed on 68000-based Macs, both as documents and stand-alone
- applications.
- - Some stand-alone applications crashed MultiFinder on startup under System 6, because
- their memory size had been set too small.
- - Bringing up a help window, closing it, and bringing it up again tended to cause
- crashes, more often on 68000-based Macs
- - The 500K default partition size seems to be a bit small for some users - memory
- management has been improved and the partition made larger
- - Error handling has improved and stands a better chance of telling you what went
- wrong in some detail rather than crashing
- - Stand-alone applications didn't close properly and could not be run again without
- restarting
- - Stand-alone applications and UpdateMaker tended to leave a partially-built file
- behind if an update failed
- - The Quit button in stand-alone applications produced a bogus error message
- - The Preferences file, which remembers override specs for particular application
- types, would not forget them if you disabled the overrides.
- - Some files under System 6 generated an incorrect warning about compressed resources
-
- Cosmetic bugs
- - The cursor flickered over the Done button in the Define Files dialog
- - The wrong icons were sometimes displayed for applications
- - The arrow between the icons in the Update specifications dialog wasn't drawn
- if the Expert options were open and the second override was disabled
- - Various dialogs didn't fit on the 512 x 342 screen properly
- - The popup menus in the expert build options lacked a down-arrow
- - The alerts didn't have appropriate icons
-
- New features for the release
- - UpdateMaker now always asks where the updated file is to be put, and behaves
- correctly if you ask it to replace the original by deleting and renaming when done.
- - The document window always appears overlapping the build window
- - The progress bar now shows .5K steps instead of 1K, and doesn't switch to
- a tick count at the end
- - The expert build options now include a control for treatment of SIZE 0 which
- allows for copy-regardless instead of the default always-replace
- - the busy cursor is now a beachball and doesn't turn into a blur
- - The stand-alone applications update dialog has been redesigned to make it clearer
- and now credits AD Instruments
- - Stand-alone applications now check to see that they have a compatible system
- version before running
- - Documents and stand-alone applications now have an internal checksum and will
- refuse to run if they have been damaged in transit
- - The description syntax has been improved as it tended to get a bit incoherent
- - The help text has been expanded
