Milestone retrospectives#

Each milestone ends with a short retrospective: what was done, the deviations from the plan (each a pragmatic choice with the same intent, and why), notes for the next milestone, and the open items for the lead maintainer (PLAN Section 0.3). Scope changes and re-estimates are made here, not in the middle of a port. The M1a retrospective holds the first re-estimate of the roadmap, summarized in Plan: the short roadmap.
