	<perex>sixth public release of Relational pipes</perex>

	<m:release>v0.14</m:release>

	<text xmlns="http://www.w3.org/1999/xhtml">

		<p>

			We are pleased to introduce you the new development version of <m:name/>.

			This release brings the Bash completion scripts, improved SQL and AWK transformations and fixes the license version.

		</p>

		<ul>

			<li>

				<strong>Bash completion</strong>:

				thanks to the Bash completion scripts, the shell now suggests/completes the CLI arguments of these commands:

				<code>relpipe-in-filesystem</code>, 

				<code>relpipe-in-xmltable</code>, 

				<code>relpipe-tr-awk</code>, 

				<code>relpipe-tr-guile</code>, 

				<code>relpipe-tr-sql</code>,

				<code>relpipe-in-sql</code>.

			</li>

			<li>

				<strong>Improved SQL transformation</strong>:

				the <code>relpipe-tr-sql</code> can now work also in the <code>relpipe-in-sql</code> mode (symlink to the same binary),

				so it can be used as an input filter for reading SQL scripts (instead of relational data) or as an SQLite client (options <code>--file</code> and <code>--file-keep</code>, see examples).

				There are also new options <code>--copy</code> and <code>--copy-renamed</code> for copying particular (or all) relations from the input to the output.

				Such relations are specified by a regular expression and can be renamed using regular expressions replacement string.

			</li>

			<li>

				<strong>Improved AWK transformation</strong>:

				this tool now supports the <code>--where</code> option, which can be used in addition to the more generic <code>--for-each</code> option.

				The argument syntax now better expresses the intention (filtering records) and matches the syntax of the <code>relpipe-tr-guile</code> tool.

			</li>

			<li>

				<strong>GNU GPLv3 license</strong>: the license version is now fixed to version 3. In the future, we can upgrade the license.

			</li>

		</ul>

		<p>

			n.b. the <code>--file</code> and <code>--file-keep</code> have been dropped in <m:a href="release-v0.16">v0.16</m:a>

			(replacement is described in the v0.16 release notes).

		</p>

		<p>

			See the <m:a href="examples">examples</m:a> and <m:a href="screenshots">screenshots</m:a> pages for details.

		</p>

		<p>

			Please note that this is still a development release and thus the API (libraries, CLI arguments, formats) might and will change.

		</p>

		<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):

		<p>

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

			In such case, it requires this patch:
