A version number says what a release promises; a cadence policy says when releases happen. Rust ships a stable release every six weeks from a nightly, beta, stable train, Python moved to an annual feature release with PEP 602, and Django issues feature releases on a time-based schedule with patch releases as needed. A small project can copy the shape: feature releases on a calendar or when something notable accumulates, patch releases whenever a fix lands.

What it is

Two families of cadence exist. Time-based: a release leaves on a date regardless of what is finished. The Rust book describes a train model in which every six weeks a beta branches from nightly and, six weeks later, becomes stable; PEP 602 moved Python to an annual release cycle with feature versions every October; the Django release process states that feature releases follow a time-based schedule while patch releases are issued as needed. Feature-based: a release happens when a planned set of changes is complete. Versioning (Semantic Versioning, linked) governs what the number promises; cadence governs when a number appears.

Why it matters

The Rust book gives the argument for trains: if a feature misses a release, the next one is close, which reduces the pressure to push unpolished work in before a deadline. For a project with one or two maintainers the opposite failure is the one to watch for: releases become rare because each one feels like an event, so fixes sit unreleased on the main branch for months and users run patched forks.

How to apply

Separate the two release kinds. Patch releases go out whenever a fix lands and CI is green; feature releases go out on a stated rhythm or when one notable change has accumulated, whichever the project can keep.
Write the policy where users look for it (README or documentation): what triggers a release, which lines are supported, and where the changelog lives.
Make a release cost minutes: a tag, a generated changelog section, a scripted publish. A cadence that depends on a manual checklist is skipped.
Declare a freeze rule for feature releases: after the cut, only fixes enter the release branch, as in the Rust beta period.
Announce with the changelog, not the tag; readers want to know what changed and whether upgrading is safe.

Pitfalls

Bumping a major version to signal marketing rather than incompatibility. Time-based trains without automated tests turn into scheduled regressions. Releasing a large batch after a long gap makes bisecting a regression expensive for users. Letting "we release when it is ready" become "we have not released this year".
