  +## Compatibility Notes
  +
  +- [core] Tighten the return type of the `getAuthHeaders()` and `buildAuthorizationHeaders()` functions.
  +- [openapi-generator] The binary of the `openapi-generator` now calls `./dist/cli.js` instead of `./bin/run`. This will be handled automatically if you install or update the CLI via `node` or run it with `npx`.
  +
  +## Improvements
  +
  +- [openapi-generator] Replace `oclif` library with `yargs`. This is a refactoring without functional changes.
  +
  +## Fixed Issues
  +
  +- [odata] Fix parsing of `Edm.Time` when some parts of the time are missing, e.g. `PT1H21S`.
  - [util] `setGlobalLogLevel(level)` sets log levels of all existing loggers globally.
  - [util] Fix `equal(item1, item2)` method to return `false` when either object is `null` or `undefined`.
  - [openapi-generator] Existing service mapping is merged with new service mapping instead of overwriting.
