Updating js-draw

In general, js-draw releases follow Semantic Versioning (semver). This means that version numbers are broken up into three parts:

• The major version (e.g. 2 in 2.1.0).
• The minor version (e.g. 1 in 2.1.0).
• The patch version (e.g. 0 in 2.1.0).

Only major version updates should include breaking changes. When a new major version is released, a new document should be added under this "Migrations" section.
