chore: bump version to 1.7.0

[felipefreitag]

Stacked on #210. Merge #210 first, then this.

What

Cuts 1.7.0 with the suppressions endpoints (#208) and the 404 error mapping (#210).

Changes

• CHANGELOG.md — promote the ## [Unreleased] heading from fix(errors): map 404 to NotFoundError instead of InvalidRequestError #210 to ## [1.7.0] - 2026-07-31, and add the suppressions entry above the existing ### Changed block. Repoint the 404 link from issue NotFoundError is never raised: ERRORS maps 404 to InvalidRequestError #209 to PR fix(errors): map 404 to NotFoundError instead of InvalidRequestError #210, to match how the 1.6.0 entries link PRs.
• CHANGELOG.md — add the missing compare-link definitions for [1.7.0] and [1.6.0]. Only [1.0.0] had one, so the 1.6.0 heading has rendered as literal brackets since it was added.
• lib/resend/version.rb — 1.6.0 -> 1.7.0
• Gemfile.lock — resend (1.6.0) -> resend (1.7.0)

Version choice

1.7.0, not 2.0.0.

The 404 change is breaking for code that rescues InvalidRequestError specifically to catch 404s, so strict SemVer points at a major. The blast radius is narrow: NotFoundError and InvalidRequestError share the ServerError parent, so anything rescuing Resend::Error or ServerError is unaffected.

A major bump signals a rewrite. 1.0.0 was a genuine Contacts API redesign. The Resend::Error::ClientError hierarchy fix is the change that warrants 2.0.0 — see the follow-up note below.

The ⚠️ changelog entry carries the migration instruction.

Follow-up, not in this PR

Resend::Error::ClientError (lib/resend/errors.rb:8) is referenced nowhere in the repo. Every 4xx code — 400, 401, 404, 422, 429 — subclasses ServerError instead. That inverted hierarchy is the root cause of #209: NotFoundError was unreachable because the tree was never wired up. 401 => InvalidRequestError has the same problem, with no auth-specific class.

Reparenting the 4xx classes is a real breaking change and belongs in 2.0.0.

Verification

Ran in a ruby:3.4 container, since the gem requires >= 3.2:

• bundle exec rspec — 336 examples, 0 failures
• bundle exec rubocop — 39 files, no offenses
• Resend::VERSION resolves to 1.7.0

Before publishing

Put the ⚠️ migration note in the GitHub release body. Auto-generated notes render #210 as fix(errors): map 404 to NotFoundError by @Mohith26 in #210, which does not warn anyone upgrading for suppressions.
