+	<perex>second public release of Relational pipes</perex>
+	<m:release>v0.10</m:release>
+
+	<text xmlns="http://www.w3.org/1999/xhtml">
+		<p>
+			We are pleased to introduce you the new version of <m:name/>.
+			This release brings Guile support and some minor changes:
+		</p>
+		
+		<ul>
+			<li>
+				<strong>Guile transformations</strong>:
+				the new tool <code>relpipe-tr-guile</code> integrates GNU Guile
+				and allows writing filters (WHERE-like conditions) and transformations (SELECT-like projections)
+				in the Scheme language.
+				Filter could look like e.g. <code>--where '(or (= $size 666) (= $size 1984) )'</code>.
+				See the <m:a href="examples">examples</m:a> page for details.
+			</li>
+		
+			<li>
+				<strong>ODS output</strong>:
+				Integer attributes are now generated with proper data type,
+				so e.g. in LibreOffice they are recognized as numbers instead of strings.
+			</li>
+			
+			<li>
+				<strong>CSV output</strong>:
+				Now generates CRLF line-ends (as defined in RFC 4180).
+			</li>
+		
+			<li>
+				<strong>Filesystem input</strong>:
+				Now allows custom relation names (option: <code>--relation</code>).
+				And default xattr namespace is now <code>user</code> so the attribute names do not have to be prefixed with <code>user.</code>.
+			</li>
+		</ul>
+		<!--
+		<p>
+			See the <m:a href="examples">examples</m:a> page for details.

+		<p>
+			Instalation was tested on Debian GNU/Linux 9.6.
+			The process should be similar on other distributions.

+		<p>
+			<m:name/> are modular thus you can download and install only parts you need (the libraries are needed always).
+			Tools <code>out-gui.qt</code> and <code>tr-python</code> require additional libraries and are not built by default.
+		</p>
+		
+		<p>
+			The module <code>relpipe-in-filesystem</code> uses C++ filesystem API which is supported since GCC 8.
+			This module can be compiled and seems usable even with GCC 6, but requires some patching (switch to the experimental API):

+			The module <code>relpipe-tr-guile</code> uses GNU Guile 2.2 but can also work with 2.0.
