+  taking a NamePool size. Poco::Util::XMLConfiguration::load() also has a new overload
+  for that purpose.
+- Improved error handling in the Zip library (getting rid of some poco_assert macros
+  and did proper error handling instead).
+- Added Poco::URISyntaxException (subclass of Poco::SyntaxException), which is now
+  thrown by Poco::URI.
+- Improved error handling in Poco::URIStreamOpener::open().
+- Poco::Data::MySQL: Handle connection lost/server gone error when starting a transaction
+  and retry.
