In professional cycling, the concept of marginal gains became famous through Team Sky. Rather than chasing dramatic breakthroughs, they focused on making hundreds of small improvements: slightly better bike fit, marginally lighter components, improved sleep, cleaner nutrition. None of these changes mattered much on their own, but together they reshaped performance—and helped dominate the sport for years.

Software systems, especially large distributed ones, work much the same way. Rarely does a single feature transform everything overnight. More often, real progress comes from careful attention to small details: shaving latency here, reducing contention there, simplifying a hot path, rethinking a data structure.

Stalwart v0.15 is very much a release in this spirit. It does not introduce a long list of headline features. Instead, it is the result of revisiting core subsystems—spam filtering, search, storage, and data access—and making many targeted improvements that, together, have a significant impact on performance, reliability, and usability.
