+
+Known issues in version 1.5.2
+------------------------------------
+
+- LyX might crash if you switch the encoding of a document while the
+ View->Source pane is opened.
+ http://bugzilla.lyx.org/show_bug.cgi?id=3561
+
+- LyX might suddenly slow down when you have copied something in another
+ instance of LyX or in another application. Known workaround: Ctrl+C of
+ some text inside the active window bring the speed back.
+ http://bugzilla.lyx.org/show_bug.cgi?id=4045
+
+- Cursor restoration problems with Multiple-View:
+ When using multiple Windows to edit different parts of the
+ same document, the cursor position is sometimes not correctly restored
+ when you switch from one view to the other.
+
+- RTL and keymaps:
+ Currently there is a bug where you can't use two non-RTL language keymaps if
+ the RTL preference is set (which is now the default). If you need to use two
+ non-RTL keymaps, for now you should just turn off the RTL preference (Tools ->
+ Preferences... -> Language settings -> Language, uncheck "Right-to-left
+ language support").
+ We hope to offer more comprehensive support for multiple keymaps in the future,
+ which will solve this bug, as well as allow more than just two keymaps. If you
+ have any input on this issue, please chime in on the developers mailing list,
+ or add your comments to http://bugzilla.lyx.org/show_bug.cgi?id=4051.
+
+
+Caveats when upgrading from earlier versions to 1.5.x
+-------------------------------------------------------
+
+Due to the change to Unicode, there are some general things you'll have to take care
+about when upgrading from an older version to LyX 1.5.0 or newer. Please refer to the
+file UPGRADING for details.
