Daylight Software Release History
Daylight releases are numbered using the following scheme:
The "system number" (e.g. 3.xx, 4.xx) indicates completely different
systems. Each system is a completely new design.
Major releases (e.g. 4.1x, 4.2x, 4.3x) contain new features and
enhancements. Often, programs and databases from one major release
aren't compatible with those from another.
Minor releases, or "updates" (e.g. 4.32, 4.33) are for bug fixes and
minor additional features. They are also occasionally for adding
new platforms (computers and/or operating-system version).
The first two releases of system 4 were called "4.1" and "4.2"; under the
above-described scheme they would have been called "4.11" and "4.21".
There were two additional releases of the "demo" tape, which would have
been "4.22" and "4.23". Release 4.24 (October '92) was the first to use
this new version-numbering scheme.
