ZF-3105: Documentation should mention that the version 1.0.4 changed Zend_Filter_Input constant name from namespace to inputNamespace
Upgrading to 1.0.4 broke some Zend_Filter_Input user code because of namespace becoming inputNamespace.
Zend_Filter_The document should create the topic how to migrate from previous versions (like 7.13. Migrating from Previous Versions - http://framework.zend.com/manual/en/…), so the 1.0.3 users should be noticed.
You may also mention the backward incompatibility here. http://framework.zend.com/manual/en/…
