- use sizeof instead strlen (by Marius Vollmer, Closes: #504325)
* doc/apt-mark.8.xml:
- improve manpage based on patch by Carl Chenet (Closes: #510286)
+ * apt-pkg/acquire-item.cc:
+ - use configsettings for dynamic compression type use and order.
+ Based on a patch by Jyrki Muukkonen, thanks! (LP: #71746)
+ * apt-pkg/init.cc:
+ - add default configuration for compression types and add lzma
+ support. Order is now bzip2, lzma, gzip, none (Closes: #510526)
+ * ftparchive/writer.cc:
+ - add lzma support also here, patch for this (and inspiration for
+ the one above) by Robert Millan, thanks!
