Uwe told me that the LyX 1.5 and 1.4.5 will come out soon. Great! But:
What is the difference between these versions? Why doesn't 1.5 fully replace
1.4.x ?
The purpose of LyX 1.4.5 is interoperability for those that do not wish to
upgrade to LyX 1.5.x at this time. The following should hold:
* LyX 1.5.0 introduces and uses a new file format (based on UTF etc)
Other releases in the 1.5-series (1.5.x) will also use this file format.
This file format will not change again until the release of LyX 1.6.0.
* LyX 1.4.5 will be capable of reading[*] files saved by LyX 1.5.x
So if you decide to upgrade to LyX 1.5.0, but you work with a colleague
that prefers LyX 1.4.x, he can use 1.4.5 to open files you have saved.
Another scenario could be that you switch to LyX 1.5.0, edit a file and
save it in the new file format. Later on you discover a bug in LyX 1.5.0
that's really bad news for you. Don't worry, just install 1.4.5 and open
the file even though it was converted to the new file format.

[*] Downgrading from the new file format may not work perfectly.
LyX 1.5.0 will use UTF, and if you insert at character that cannot
be represented by the old file format, then converting to the old
file format will replace the unrepresentable character with a
placeholder (???).
