MicroProfile, an Open-Source Community that collaborates on enterprise Java microservices, would like to announce the release of MicroProfile 4.1.
MicroProfile 4.1 is the 2nd version released by the recently-formed MicroProfile Working Group. This is the first release defining the compatible implementation requirements, as follows.
- [Required] Passing the 8 MicroProfile Specification TCKs
- [Optional] Passing the 5 Jakarta Specification TCKs
The Compatibility Certification Request (CCR) requirement regarding compatibility with Java SE 8 has been lifted to any version matching Java SE 8 or higher. The release follows the new MicroProfile Specification Process, a compatible specialization of the Eclipse Foundation Specification Process, that adds agility to the release process to continue to meet the MicroProfile three times per-year (February, June & October) release cadence.
Finally, MicroProfile Health included in the MicroProfile 4.1 platform has been updated with new features to meet the needs of its growing developer base while the other 7 MicroProfile specifications remain unchanged. As a minor release, MicroProfile 4.1 does not include incompatible changes.
