+* Minor user interface improvements
+
+Several minor improvements of the user interface have been made, such as:
+
+ - Syntax highlighting of the user preamble and the LaTeX log file.
+ - Better parsing of BibTeX databases (in the citation dialog).
+ - Support for optional arguments for environments.
+
+* Enhanced clipboard/selection handling
+
+The clipboard has been tuned to work better with other applications.
+Parallel to clipboard usages, the *nix way of using middle-button
+to paste selected text is enhanced, and is also available under windows
+(but within lyx only). Selection of lyx text is now persistent in that
+you can paste the selected text using the middle button multiple times,
+even after the selection has been cleared.
+
+* Limited support for local class and layout files
+
+Lyx can not create, but can open a .lyx file with .cls and .layout files
+stored in the same directory as the .lyx file. That is to say, if you send
+your co-author a .lyx file with associated class and layout files, s/he
+can view and modify the .lyx file directly, without having to install the
+.cls and .layout files, reconfigure and restart lyx. Note that the .cls and
+.layout files have to be copied to every directory your .lyx files reside,
+should you use different directories for master and child documents.
+
+* Under the hood
+
+As usual, one big task has been the ongoing code cleanup of the LyX
+core. Performing this cleanup makes the code more understandable and
+easier to maintain. It also leads inevitably to a more robust
+application. Nonetheless, it's an unfortunate fact of life that ugly
+code is sometimes faster than pretty code. We're well aware that LyX
+1.4 is slower than LyX 1.3. One important goal of this 1.5 development
+series has been to bring this speed back.
