Upgrade to 1.4.5.1. This is the maintenance release and is expected
to be last 1.4.x release.

Too many changes to list here.  "Besides the obligatory bug fixes,
its main feature is the ability to read filescreated by LyX 1.5.0
(this feature requires python 2.3.4 or later)."

(1.4.5 was not released).

The 1.4.4 release had these new features:

- Outline support: it is now possible to move around parts of
  documents in the Table of Contents dialog.

- Add new UI settings default-autotoolbars and default-alltoolbars
  allowing to select what toolbars are active or shown automatically.

- Improved documentation.

- Speed improvments, especially on windows.

(See lyx.org website to see all changes.)
