10### Fixed

12- Reduced opam package size from 87MB to ~200KB by using `git archive` for tarball creation

14## [0.2.1] - 2026-01-04
15
16### Fixed
17
18- **Server port binding now fails correctly when port is already in use.** Previously, `reuse_port` defaulted to `true`, which enabled `SO_REUSEPORT` and allowed multiple processes to silently bind to the same port. This caused confusing behavior where a new server would start successfully but only receive a fraction of connections. Now `reuse_port` defaults to `false`, and binding to an already-used port will fail with a clear error.

20### Changed
21
22- `Server.default_config.reuse_port` now defaults to `false` instead of `true`.
23- Users who intentionally want multiple processes sharing a port (for load balancing) can enable it explicitly via `{ config with reuse_port = true }`.
