// We are moving to a rough ~2 years back support rather than a 2 versions
|
|
// back support. This strikes a balance between folks who need to get a job
|
|
// done in the Consul UI and keeping the codebase modern and being able to use
|
|
// modern Web Platform features. This is not set in stone but please consult
|
|
// with the rest of the team before bumping forwards (or backwards)
|
|
// We pin specific versions rather than use a relative value so we can choose
|
|
// to bump and it's clear what is supported.

// async/await support came before the below specified versions for Chrome,
|
|
// Firefox and Edge. Async/await is is the newest ES6 feature we are not
|
|
// transpiling. Safari's template literal support is a little problematic during
|
|
// v12 in that it has a GC bug for tagged template literals. We don't currently
|
|
// rely on this functionality so the bug wouldn't effect us, but in order to use
|
|
// browser versions as a measure for ES6 features we need to specify Safari 13
|
|
// for native, non-transpiled template literals. In reality template literals
|
|
// came in Safari 9.1. Safari's async/await support came in Safari 10.
