 ### Version History
 
+- **1.0.0-beta.5 (October 19, 2026)** - Installs with npm on a host without Bun: the TypeScript 6 pin for the lint tools runs from `prepare`, not `postinstall` ([bc-components-ts#11](https://github.com/BlockchainCommons/bc-components-ts/issues/11)).
 - **1.0.0-beta.2 (September 16, 2026)** - Constructor names (`makeFromUtf8`, `makeFromData`, `makeFromDigest`), `hasAlpha` and `colors`; images of any size a `number` can count render;
 - **1.0.0-beta.1 (September 16, 2026)** - Initial beta implementation.
