<h2>New features in 0.8.2<a class="headerlink" href="#new-features-in-0-8-2" title="Link to this heading">¶</a></h2>
<p>This does not list bugfixes, enhanced internals or api additions.</p>
<blockquote>
<div><ul class="simple">
<li><p>“Shadow history” remembers everything you’ve entered, forever. Remember that
arcane command line you entered three weeks ago? Just grep the shadow
history with “%hist -g”! <a class="reference external" href="http://ipython.scipy.org/moin/Cookbook/ShadowHistory">See cookbook</a> for details.</p></li>
<li><p>%rep is a new magic function that allows you to fetch command lines from
history for editing. Do “%rep?” for details.</p></li>
<li><p>System command aliases (created by %rehashx) are lower case in win32.</p></li>
<li><p>Macros can now take arguments. <a class="reference external" href="http://ipython.scipy.org/moin/Cookbook/MacroArguments">See cookbook</a>.</p></li>
<li><p>%macro without arguments lists available macros.</p></li>
<li><p>Directory history (the easiest way to see it is by doing ‘cd -<TAB>’) is now
persistent across sessions.</p></li>
<li><p>ipython -i -c <cmd>: -i (interact) prevents IPython session from exiting
after executing <cmd>. <cmd> can now contain IPython syntax (!foo, %magic
etc).</p></li>
<li><p>new profiles: doctest, zope. scipy is now in ipy_profile_scipy.py instead of
ipythonrc-scipy.</p></li>
<li><p>new extensions:</p>
<ul>
<li><p>ipy_traits_completer.py: complete Traits attributes</p></li>
<li><p>ipy_legacy.py: enable deprecated features</p></li>
<li><p>mglob.py: enhanced globbing - <code class="docutils literal notranslate"><span class="pre">%mglob</span> <span class="pre">!.svn/</span> <span class="pre">rec:*.py</span></code></p></li>
<li><p>ipy_exportdb.py: create a portable .py file from your %store’d macros,
aliases, strings and bookmarks for distribution. <a class="reference external" href="http://ipython.scipy.org/moin/Cookbook/IpyExportDb">See cookbook</a> .</p></li>
<li><p>ipy_render.py: win32: render templates using Itpl format to clipboard
(e.g. render ‘hello $a’). <a class="reference external" href="http://ipython.scipy.org/moin/Cookbook/IpyRender">See cookbook</a>.</p></li>
<li><p>ipy_editors.py: Bunch of popular editors readily configured for
IPython. See ipy_user_conf.py for instructions on how to enable them.</p></li>
<li><p>ipy_fsops.py: Has useful shell utils for plain (non-cygwin enabled) win32
installations: icp, imv, imkdir, igrep, irm, collect (collect is useful
for others as well).</p></li>
</ul>
</li>
<li><p>py2exe version supported (ipykit)</p></li>
<li><p>The title bar of IPython window shows the currently executing system
command.</p></li>
<li><p>Prompt on win32 in pysh (‘-p sh’ profile) now has the drive letter for
enhanced location awareness, and uses / instead of .</p></li>
<li><p>Errors from misusing magics are much less verbose now (due to UserError
exception).</p></li>
<li><p>String Lists provide a convenient way to manipulate command output. See
<a class="reference external" href="http://ipython.scipy.org/moin/Cookbook/StringListProcessing">Cookbook</a>.</p></li>
<li><p>Directory stack (%pushd, %popd, %dirs) works more predictably now.</p></li>
<li><p>%time allows IPython expressions (which includes system commands - e.g. try
“%time !ls”)</p></li>
<li><p>Callable aliases can be used to extend IPython (provide new commands) in a
more elegant manner than magic commands. Also, no % is
necessary/allowed. See ipy_fsops.py for examples.</p></li>
<li><p>Improved Leopard support for tab-completion, though a few issues remain.</p></li>
</ul>

<h2>Known issues<a class="headerlink" href="#known-issues" title="Link to this heading">¶</a></h2>
<blockquote>
<div><ul class="simple">
<li><p>We still get crashes from KeyboardInterrupt occasionally (caused by pressing
ctrl+C or ctrl+break)</p></li>
<li><p>Unicode support is not yet perfect, so expect problems on Unicode
input/output.</p></li>
<li><p>The manual is hopelessly out of date. This is something we will look into
during 0.8.3 cycle; in the meantime, see the documentation page on the wiki
[superseded], and the user-maintained <a class="reference external" href="http://ipython.scipy.org/moin/Cookbook">cookbook</a>.</p></li>
<li><p>Under OSX Leopard, we are seeing some readline-related problems with history
recall. It is not clear yet whether the issue is with IPython or Leopard’s
readline support itself. We’re investigating the issue.</p></li>
