ECF 3.5.1 is released. See here  for download. The Indigo release review materials (for ECF 3.5.1 as contribution to Indigo simultaneous release) are here . The git tag is here .
The main changes for this maintenance release are bug fixes...particularly those around ECF's compliance with the OSGi RSA TCK. ECF 3.5.1 not only fully implements the OSGi 4.2 RSA specification (enterprise spec chap 122), it now has passed the TCK test cases. Another area of great improvement is documentation . We are making great progress...please continue contributing to the ECF documentation project .
ECF 3.5.1 will be our contribution to the Indigo simultaneous release.
Congratulations to the ECF committers, contributors, and community for a successful release.
