<h1>Hugin-2009.4.0 release notes</h1>
<p>Hugin is a panorama stitcher and more.</p>
+
+<!-- Note for proof readers/editors: Although this document is ostensibly a
+list of new features, it gets copied and distributed to suprising locations, so
+as a result most readers are unlikely to have used Hugin before. i.e. the
+audience of this document is somebody who has an idea what a panorama stitcher
+might be, has never heard of Hugin, but is interested in discovering cool new
+software. -->

<h2>Changes since 2009.2.0</h2>
<p>The last release was barely a month ago, but we have a backlog of new
features ready to go. So keeping with the intention of tracking development
better with more frequent releases, Hugin now brings you two major new features
-as well as the usual bugfixes and minor improvements:</p>
+as well as the usual bugfixes and incremental improvements:</p>
<h3>Automatic lens calibration</h3>
-<p>Hugin is already a great tool for calibrating lenses, by stitching a
-panorama Hugin will calculate <em>barrel distortion</em> and <em>angle of
-view</em> for any lens. Plus there is everything a power user might want:
-different lenses can be calibrated in a single project, fisheyes and shift
-lenses pose no problems to the Hugin <em>optimiser</em>.</p>
+<p>Hugin is already a great tool for calibrating lenses; by stitching a
+panorama Hugin will automatically calculate <em>barrel distortion</em>,
+<em>vignetting</em> and <em>angle of view</em> for any lens. Plus there is
+everything a power user might want: different lenses can be calibrated in a
+single project, fisheyes and shift lenses pose no problems to the Hugin
+<em>optimiser</em>.</p>
-<p>Though panoramas are not the only way to calculate lens parameters;
-<em>barrel distortion</em> turns straight lines into curves, so figuring out
-how to straighten them again is enough to accurately calibrate a lens - All you
-need is an object with lots of straight-lines, such as a modern building, and
-one or more photographs of it.</p>

<p>This year Tim Nugent was employed by Google Summer of Code to add a new
-Hugin command-line tool called <em>calibrate_lens</em> that takes photos as
-input and produces calibration parameters as output. There isn't yet a
-graphical interface, this release provides a base to build future
-tools.</p>
+Hugin tool called <em>calibrate_lens</em>, this takes such photos as input and
+produces calibrated parameters as output. There isn't yet a graphical
+interface, but the command-line tool works well and provides a base to build
+future tools.</p>
<h3>Control point cleaning</h3>
-<p>FIXME</p>
+<p>Hugin aligns photos using a system of <em>control points</em>; these are
+features from the scene that appear in each pair of overlapping photos.
+Normally just a handful of features are needed to get a good result, but they
+do need to be identified - This can be done either by picking them in the Hugin
+<em>Control Points tab</em> or by using one of the automatic <em>control point
+creator</em> plugins such as <em>autopano-sift-C</em> or
+<em>pan-o-matic</em>.</p>
+<p>These <em>Control point creators</em> are incredibly convenient, but still
+make mistakes that are obvious to the human eye. Hugin now filters
+automatically generated points to remove those that are statistically
+improbable. The same filter can be used to 'clean' an existing project on the
+<em>Images tab</em>, and is available as a new scriptable command-line tool
+called <em>cpclean</em>.</p>
+
<h3>Languages</h3>
-<p>Most translations have been updated.</p>
+<p>The Hugin application is translated into twenty languages, most of these
+translations have been updated for this release.</p>
<h3>Other improvements</h3>
-<p>
-OS X build fixes.
-Windows build fixes.
-Linux build fixes.
-Crashes.
-Crop inversion bug.
-Minor manual updates, now displays in system browser, the manual is still a few months behind development.
-Fix to display original EXIF capture date.
-Control point picker settings are now persistent between sessions.
-</p>
+<p>This release also has the usual incremental improvements: building on
+Windows, Linux and OS X is now easier, some crashes in obscure situations have
+been fixed, more useful photo EXIF metadata is shown in the <em>Images
+tab</em>, the manual now displays in your default system web-browser, a bug
+where upside down crop rectangles confused the stitcher is fixed, and an
+annoyance where control point settings were not persistent between sessions is
+gone.</p>
-<p>There are many more improvements to Hugin in this release: More options in
-the preferences, better error messages for when things do go wrong, fixes for
-lots of reported bugs, and better support for packagers on BSD, Linux, OS X and
-Windows.</p>
+<!-- Note for translators: the rest is the same as the previous release announcement -->
<h2>Control point generators</h2>
<p>Hugin doesn't yet ship with a 'Patent Free' control point
