In 2014, we announced the retirement of our legacy forum, forum.spring.io, in favor of providing an improved community experience on stackoverflow.com. As part of that announcement, we put our forum into read-only mode, preserving forum posts that were referenced in various Spring issue trackers.
On February 28, 2019, we plan to take the forum completely offline. In preparation for this end-of-life activity, we have gone through our issue trackers and identified links to forum.spring.io that contain supplementary information related to an issue. Based on this analysis, we have either copied such text directly into the issue tracker or otherwise ensured that no essential information is lost.
