Dear Spring community,
With Spring Framework 5.2.2 and 5.1.12 being available now, let me take the opportunity to provide an update on the maintenance roadmap in 2020.
Most importantly, Spring Framework 4.3.x and therefore Spring Framework 4 overall will reach its end-of-life next year: Our EOL cut-off is December 31st, 2020, with no further support on 4.3.x beyond that point. At the same time, we are also phasing out 5.0.x and 5.1.x for good.
As for planned releases, first up is a full round in mid January: with 5.2.3 and 5.1.13 accompanied by 5.0.16 and 4.3.26. The latter are the last maintenance releases in the 5.0.x and 4.3.x lines. We may do critical patches in case of vulnerabilities but otherwise no further releases are planned in those lines until the final cut-off at the end of 2020.
