During February 2025, David Fennessy focused on updating documentation within the infinispan/infinispan repository to support the upgrade of JGroups from version 4 to version 5. He revised AsciiDoc-based resources to ensure all manual and schema references accurately reflected the new JGroups v5 and schema 5.4, addressing potential reference drift and streamlining onboarding for developers. His work centered on documentation skills and AsciiDoc language, with no bug fixes or new features beyond these updates. The changes improved the accuracy and consistency of technical documentation, aligning with the project’s upgrade roadmap and supporting developer adoption of the latest JGroups version.
