-	<li>To compile the Python interface for recoll 1.12, you need
-	  to edit setup.py and replace "rcldb/pathhash.cpp" with

-	<li>Performing a full index with release 1.11 or later, over a
-	  version created with a much older recoll release may
-	  sometimes end with an error saying "backend doesn't
-	  implement metadata".  If this happens, you need to delete
-	  the index directory (typically <em>~/.recoll/xapiandb/</em>)
-	  and restart indexing. For big indexes, removing the
-	  directory preventively may be preferable to avoid losing
-	  time.</li>
-
-	<li> When Recoll is built with qt 4.4.0, the icons in the
-	  result list are all displayed at the top of the page and
-	  garbled. This appears to be a qt bug, fixed in 4.4.1. Use
-	  either qt 4.3.x or 4.4.1</li>
-
-	<li> If the user-chosen result list entry format results in
-	  several paragraphs (in the qt textedit sense), right clicks
-	  will only work inside the first one for each entry.</li>
-
-	<li> When a mime type has an external viewer defined, but the
-	  actual file is compressed (ie: xxx.txt.gz), recoll will try
-	  to start the external viewer on the compressed file, which
-	  will not work in most cases.</li>
-
-	<li>NEAR expansion errors: recoll performs stemming expansion
-	  inside NEAR clauses (except if prevented by a capitalized
-	  entry). Because of a Xapian bug (at least up to 1.0.10),
-	  NEAR does not support multiple OR subclauses. This manifests
