The last major release was V2 in 2020-02-22.

List of breaking changes to include:

• Drop Node 13 support
• Remove old items from lib/helpers/deprecated-rules.js
• Include support for linting .html files (#1232 )
• Update catchNonexistentRoles option to default to true in no-invalid-role
• Update noImplicitThis option default to true and requireDash option default to false in no-curly-component-invocation rule (#1642)
• Update rule to default to strict behavior in link-rel-noopener
• New stylistic rules (#1638) (see current list of rules here):
  • modifier-name-case
  • no-whitespace-for-layout
  • no-whitespace-within-word
• Promote all octane rules to the recommended config (and delete the octane config) since all supported Ember LTS versions are Ember Octane now (3.16, 3.20, 3.24) (#1639)
• New recommended rules (#1643) (see current list of rules here):
  • builtin-component-arguments
  • deprecated-each-syntax
  • deprecated-inline-view-helper
  • no-accesskey-attribute
  • no-arguments-for-html-elements

  • no-unbalanced-curlies
  • no-yield-only
  • require-input-label - requires input elements to have associated labels. The rule is a bit permissive (because it has to be in this context) but it should catch common instances of this issue.
  • require-lang-attribute
  • splat-attributes-only
• Fix newly-introduced bug with rule configurations https://github.com/ember-template-lint/ember-template-lint/issues/1644
• Rules override is reversed on extends #1417

Final check before release:

• make sure all rulesets are updated
• double check recommended ruleset

@rwjblue I see. I think it’s generally better to change the default in the rule itself, but that works for now.
