+Changes
+=======
+
+v0.97
+-----
+First release integrated with luatex sources, plus portability changes from Luigi.
+
+v0.98
+-----
+Changed references resolving in case of incremental updates; tech notes ppxref_find() in ppxref.c.
+
+v0.99
+-----
+Fixed streams handling; null characters should NOT be gobbled after "stream" keyword
+
+v1.00
+-----
+Fixed streams handling (Luigi); object streams updated before other streams
+Revised streams handling, ppstream API extended
+
+v1.01
+-----
+Fixed names handling (thanks Hans); digits after '#' weren't skipped
+
+v1.02
+-----
+Fixed page finder (thanks Luigi)
+
+v1.03
+-----
+Fixed TIFF predictor (thanks folks)
+
+v1.04
+-----
+Fixed TIFF predictor for ARM
+
+v1.05
+-----
+Attempt to fix parsing inline images crap
+
+v2.00
+-----
+Deep rework on allocators.
+Deep rework on strings and names.
+
+v2.01
+-----
+Fixed invalid stream buffer handling; ``iof_discard()`` no longer reclaims the source (``filter->next``) filter.
+Sanity alignment adjustments in ``iof_heap``.
+
+v2.02
+-----
+Fixed incorrect encoding of strings alterego with octal escaping, thanks Luigi.
+On Hans request added ``ppdoc_filehandle()`` function and ``ppdoc_file()`` macro for loading ppdoc from ``FILE *``.
+
+v2.03
+-----
+Fixed alloc/free of ``ppdoc`` heap; ``ppdoc`` is now mallocated, no longer taken from its own heap. Again, thanks Luigi.
+Fixed warnings about dereferencing type-puned pointers, and some others.
+
+v2.04
+-----
+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.
+
+v2.05
+-----
+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..)
+
+TODO
+====
+- external streams (egzotic)
