Hi folks,
I think the best for commons-email-1.3 will be reverting the changes of
the setters from
Email setXXX(arg)
to
void setXXX(arg)
which in turn gives me binary backward compatibility. I would like to
see a commons-email-1.3 out there which gives me time to work on 2.0
Cheers,
Siegfried Goeschl

Hi folks,
the main reason for the failed vote of commons-email-1.3 is that the release
is only source but not binary compatible
+) if you compile your application with the new version everything is fine
+) if you replace simply the JAR the invocation fails
Is it mandatory that a minor release is binary compatible with the previous
one or do I have to create a new major version? There is a lot of ugly stuff
(mainly protected member variables) which should be done but is currently
not in the scope of this release.
If the jar is not a drop-in replacement for the previous version, then
yes, IMO that requires a major release. [1]
The only possible exception might be if the incompatibilities are in
internal parts of the API, i.e. classes/methods etc. that are not used
externally.
Note also that a binary incompatibility involving the external API
will also require the package name to be changed (which in turn
requires the Maven coordinates to be changed).
The package name change is required because there can be only one
instance of a class in a single class loader.
