+Code has been heavily refactored, taking care to preserve backwards compatibility as much as possible,
+but some breackage is to be expected.
+
+PLEASE READ CAREFULLY THE NOTES BELOW to insure a smooth upgrade.
+
+The minimum required php version has been increased to 5.3,
+even though we strongly urge you to use more recent versions.
+
+* new: introduction of namespaces.
+
+ All php classes have been renamed and moved to separate files.
+ Class autoloading can now be done in accord with the PSR-4 standard.
+ Backward compatibility is maintained via lib/xmlrpc.inc, lib/xmlrpcs.inc and lib/xmlrpc_wrappers.inc.
+
+* improved: all php code is now formatted according to the PSR-2 standard
+
+* improved: this release is now tested using Travis ( https://travis-ci.org/ ).
+ Tests are executed using all php versions from 5.3 to 7.0 nightly, plus HHVM; code-coverage information
+ is generated using php 5.6 and uploaded to both Code Coverage and Scrutinizer online services
+
+* improved: no need to call anymore $client->setSSLVerifyHost(2) to silence a curl warning when using https
+ with recent curl builds
+
+* improved: phpunit is now installed via composer, not bundled anymore
+
+* improved: when phpunit is used to generate code-coverage data, the code executed server-side is accounted for
+
+* improved: debug messages are not html-escaped any more when executing from the command line
+
+* improved: a specific option allow users to decide the version of SSL to use for https calls.
+ This is useful f.e. for the testing suite, when the server target of calls has no proper ssl certificate,
+ and the cURL extension has been compiled with GnuTLS (such as Travis)
