<h1>Hugin-2010.0.0 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 2009.4.0</h2>

<p>The Hugin plan is to bring you new developments as soon as they are ready
with regular incremental releases.  This first release in 2010 brings some new
features, more results from the <em>2009 Google Summer of Code</em> and many
general improvements.</p>

<h3>Usability</h3>

<p>The Hugin <em>Fast Preview window</em> is where you see a rough preview of
the final panorama and can edit it with a selection of tools &mdash; For
example, one of several 'modes' is <em>Drag</em> for moving photos around the
canvas, there are also single click 'actions' to do things like reset the
exposure or center the view.</p>

<p>Now these tools have been overhauled to make them easier to find, to get a
bigger panorama canvas, and to create space for new features in the pipeline
such as the upcoming <em>Layout mode</em>. Switching 'modes' is more intuitive,
with a tab for each that shows just the 'actions' relevant to that mode, the
<em>&lt;F11&gt;</em> key enables full-screen viewing of the preview.</p>

<p>There are other usability-related changes &mdash; the <em>Hugin main
window</em> can also be viewed full-screen with <em>&lt;F11&gt;</em>; more
photo EXIF metadata is displayed in the Images tab; a list of recent projects
is available in the <em>File menu</em>; plus there has been a general clean-up
of text in the GUI and many updates to the manual.</p>

<h3>Autocrop</h3>

<p>Hugin is great for stitching hand-held panoramas, but nobody can shoot in
perfect straight lines, so these panoramas need careful cropping to produce a
picture with 100% coverage. The <em>Fast Preview window</em> now has an
<em>Autocrop</em> button that does all this for you automatically &mdash; Just
click, and the crop rectangle will be resized to use the largest possible area
covered by your photos.</p>

<h3>Deghosting</h3>

<p>One of the advanced Hugin features is to merge bracketed photos using
<em>exposure fusion</em> or <em>HDR merging</em> - This is done automatically
when stitching when bracketed sets are detected.</p>

<p>However, when people or objects move during a bracketed sequence, 'ghosts'
appear in the result. So another Summer of Code project has now been integrated
that both enables <em>HDR deghosting</em> in the GUI and provides an
experimental <em>deghosting_mask</em> tool for <em>exposure fusion</em>
deghosting with enfuse.</p>

<h3>Languages</h3>

<p>With the addition of a Finnish translation, the Hugin application is now
internationalized for twenty-one languages, most of the translations have been
updated for this release.</p>

<h3>Other improvements</h3>

<p>This release also has the usual incremental improvements: The default size
of the image cache has increased in line with modern computers, so existing
Hugin users may want to check or reset their <em>Preferences</em> to suit; the
<em>About dialog</em> has been extended to show a full list of Hugin
contributors, and there have been many other fixes for minor bugs and
annoyances.</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
generator. So you either need to pick control points manually - Not
as difficult as it sounds - or install and configure one of the
following control-point generators as 'plug-ins':</p>
<ul>
<li>autopano-sift-C</li>
<li>panomatic</li>
<li>match-n-shift</li>
<li>Autopano-SIFT</li>
<li>Autopano freeware version</li>
</ul>
<h2>Upgrading</h2>
<p>Upgrading from previous versions of Hugin should be seamless. If
you do have problems with old settings, these can be reset in the
Preferences by clicking 'Load defaults'.</p>

<p>For users compiling from source: note that the minimum version of
<em>wxWidgets</em> supported is now 2.7.0, libpano13 needs to be at least
2.9.14, and that Hugin now requires <em>GLEW</em> the OpenGL Extension Wrangler
Library, <em>freeglut</em> the OpenGL utility toolkit, and <em>libGLU</em> the
OpenGL utility library.</p>

<p>Support for the legacy libpano12 library has been discontinued.</p>

<p>See the README and INSTALL_cmake files for more
information.</p>

the hugin-ptx mailing list, too many to mention here.</p>
