Versioning

Since version 9 we are adopting a new versioning strategy. With every release, we are going to update two urls

• A) The latest release will always be available on https://connect.trezor.io/9/trezor-connect.js.
• B) For those who like to have more control over their dependencies, there will be also a new url created in form of https://connect.trezor.io/9.1../trezor-connect.js. Please note that these endpoints will not receive any further updates including security updates.

Version 9 is available as @trezor/connect and @trezor/connect-web npm packages.

Major version

New major version is released when there are breaking changes on API level. Previous major version will be maintained for 12 months and after this period it can be taken down without notice.

Current major version 9 is being developed on top of develop branch. When there is a new major version a new branch should be created (v-<major-version>) and mantained separately.

Minor version

Minor versions are released when there are:

• considerable additions to API
• changes in npm package

Patch version

Everything else that does not fall under major or minor version.

Version 8 (legacy)

Legacy version 8 is accessible from url https://connect.trezor.io/8/trezor-connect.js.

Version 8 is available as trezor-connect npm package.

If you would like to find out which version is deployed precisely simply run:

curl -s https://connect.trezor.io/8/trezor-connect.js | grep VERSION

With regards to this repo - All updates should go to current version branch, the previous releases are in corresponding branches. The gh-pages is the same older version, that is used at trezor.github.io/connect/connect.js, and it's there for backwards compatibility; please don't touch.
