I'm wondering whenever it makes sense to switch seabios to time-based releases, like many other projects do meanwhile.
For major releases one release per year looks reasonable to me, given the low rate of changes we have. 1.11 was tagged in November 2017. So maybe target 1.12 for November 2018 ?
For stable releases we could plan to create a release every one or two months. Skip in case there are no patches queued. Or stick to the current model which kind-of syncs stable releases to qemu releases (which is roughly every four months).
