* 8.1.0: release
2018-06-22 Jay Berkenbilt <ejb@ql.org>
* Bug fix: properly decrypt files with 40-bit keys that use
revision 3 of the security handler. Prior to this, qpdf was
reporting "invalid password" in this case. Fixes #212.

merging files.

When splitting files, qpdf detects fonts and images that the
document metadata claims are referenced from a page but are
not actually referenced and omits them from the output file.
This change can cause a significant reduction in the size of
split PDF files for files created by some software packages.
Prior versions of qpdf would believe the document metadata
and sometimes include all the images from all the other
pages even though the pages were no longer present. In the
unlikely event that the old behavior should be desired, it
can be enabled by specifying
<option>--preserve-unreferenced-resources</option>. For
additional details, please see <xref
linkend="ref.advanced-transformation"/>.

When merging multiple PDF files, qpdf no longer leaves all
the files open. This makes it possible to merge numbers of
files that may exceed the operating system's limit for the
maximum number of open files.

<para>
The <option>--rotate</option> option's syntax has been
extended to make the page range optional. If you specify
<option>--rotate=<replaceable>angle</replaceable></option>
without specifying a page range, the rotation will be
applied to all pages. This can be especially useful for
adjusting a PDF created from a multi-page document that
was scanned upside down.

When the <option>--progress</option> option is specified,
qpdf will print a running indicator of its best guess at how
far through the writing process it is. Note that, as with
all progress meters, it's an approximation. This option is
implemented in a way that makes it useful for software that
uses the qpdf library; see API Enhancements below.

The first round of higher level &ldquo;helper&rdquo;
interfaces has been introduced. These are designed to
provide a more convenient way of interacting with certain
document features than using
<classname>QPDFObjectHandle</classname> directly. For
details on helpers, see <xref
linkend="ref.helper-classes"/>. Specific additional
interfaces are described below.
</para>
</listitem>
<listitem>
<para>
Add two new document helper classes:
<classname>QPDFPageDocumentHelper</classname> for working
with pages, and
<classname>QPDFAcroFormDocumentHelper</classname> for
working with interactive forms. No old methods have been
removed, but <classname>QPDFPageDocumentHelper</classname>
is now the preferred way to perform operations on pages
rather than calling the old methods in
<classname>QPDFObjectHandle</classname> and
<classname>QPDF</classname> directly. Comments in the header
files direct you to the new interfaces. Please see the
header files and <filename>ChangeLog</filename> for
additional details.

Add three new object helper class:
<classname>QPDFPageObjectHelper</classname> for pages,
<classname>QPDFFormFieldObjectHelper</classname> for
interactive form fields, and
<classname>QPDFAnnotationObjectHelper</classname> for
annotations. All three classes are fairly sparse at the
moment, but they have some useful, basic functionality.

A new example program

The method
<function>QPDFWriter::registerProgressReporter</function>
has been added. This method allows you to register a
function that is called by <classname>QPDFWriter</classname>
to update your idea of the percentage it thinks it is
through writing its output. Client programs can use this to
implement reasonably accurate progress meters. The
<command>qpdf</command> command line tool uses this to
implement its <option>--progress</option> option.

New methods
<function>QPDFObjectHandle::newUnicodeString</function> and
<function>QPDFObject::unparseBinary</function> have been
added to allow for more convenient creation of strings that
are explicitly encoded using big-endian UTF-16. This is
useful for creating strings that appear outside of content
streams, such as labels, form fields, outlines, document
metadata, etc.

A new class
<classname>QPDFObjectHandle::Rectangle</classname> has been
