Release v4.5.0

[richdawe-cio]

Changed

• BREAKING: Drop support for Node.js versions that have reached end-of-life. Supported versions now follow the Node.js release schedule — Current, Active LTS, and Maintenance LTS only (currently Node.js 22, 24, and 26). Added an engines field to package.json. (#180)
• BREAKING: Fix triggerBroadcast API path by removing erroneous /api prefix, and rename the id parameter to broadcastId for clarity (#179)
• Bump third-party dependencies: @types/node, @types/sinon, ava, js-yaml, lodash, minimatch, nyc, picomatch, pretty-quick, sinon (#167, #169, #177, #178, #181)

Added

• Add body property to SendEmailRequestWithTemplate type definition (#172)

Fixed

• Add timeout handling for HTTP requests (#173)

Note

Low Risk
Primarily a version/changelog release update; runtime risk is low, but the documented Node.js support drop is breaking for consumers on older Node versions.

Overview
Cuts release 4.5.0 by bumping the package/version constants (package.json, package-lock.json, lib/version.ts) and updating CHANGELOG.md with the 4.5.0 notes.

The release notes document breaking Node.js support changes (now node >=22 via engines), plus prior fixes/additions like triggerBroadcast path/param corrections, dependency bumps, an added SendEmailRequestWithTemplate.body type, and HTTP request timeout handling.
