<h2>v2.04<a class="headerlink" href="#v2-04" title="Permalink to this headline">¶</a></h2>
<p>Byte lookups for names/strings loaders are now int8_t, as char might be signed.
ppdoc_first_page() / ppdoc_next_page() iterator now handles a case when /Kids array is empty.
Fixed generating keys for encrypted streams; ppstring_internal() returns the string of the proper size.
More stream tests in pptest3.c.
Some rework on md5 and sha2.</p>

<div class="section" id="v2-05">
<h2>v2.05<a class="headerlink" href="#v2-05" title="Permalink to this headline">¶</a></h2>
<p>uint8_t instead of ppbyte in internals; ppbyte intent is “the most natural 8-bit integer”, so it is ‘char’,
but internally we almost always need uint8_t (char may be signed or not..)</p>
