### Performance Improvements:

* interval: subtract normalized sets with a linear sweep by Tobias Bohwalli

## Unreleased

### Changed

- Weekly recurrence uses Monday-anchored intervals and bounded traversal.
  Invalid local times are skipped without consuming COUNT; COUNT and UNTIL
  together now return an error.
- Duplicate resource IDs, malformed options, unsupported JSCalendar recurrence
  fields and empty FREEBUSY periods now return explicit errors.
- Closed-day overrides remove inbound overnight availability. Collective
  preferences retain all required participants, and alternatives preserve
  request preferences.
- Lead-time checks, slot deduplication, hold matching and assignment ordering
  preserve microsecond precision. Missing fairness ranks explicitly, and
  weighted assignment supports arbitrarily large integer counters.
- Interval subtraction normalizes both sets and uses a linear sweep after
  sorting. Pool capacity uses peak simultaneous reservation consumption.
- Shared validation removes redundant work and unreachable fallback branches;
  public types describe supported strategies and partial fairness maps.

### Maintenance

- Update Mint to 1.10.0, ExDoc to 0.40.4 and Req to 0.7.4; add Hex registry
  advisory checks alongside the existing dependency audit.
- Update pinned checkout/cache actions and add weekly security checks and
  dependency update proposals.
- Expand behavioral properties, package notebook sources, verify extracted Hex
  archives in fresh consumers, execute notebook setup cells, and separate smoke
  benchmarks from full performance measurements.

These unreleased changes alter recurrence results and malformed-input handling.
Consumers should review those behavior changes before upgrading.
