+## [1.2.0] - 2026-09-20
+
+### Added
+- `list_email_suppressions` for `GET /email-suppressions` with optional `email`, `cursor`, and `limit` query parameters. Pass `email` to check a single address; an empty collection means it is not suppressed.
+- `delete_email_suppression` for `DELETE /email-suppressions/{id}`
+- `Pylon::Models::EmailSuppression` model (`id`, `email`, `reason`, `created_at`, `bounce_details`)
+
+### Changed
+- Documentation only: README examples now use `body_html` when creating issues and note the 365-day window for `list_issues`. No existing method signatures, paths, or return types changed.
+
+## [1.1.1] - 2025-04-18
+
+### Fixed
+- Fixed URL-based file attachments by ensuring they use proper multipart form encoding

+#### Email Suppressions
+
+Pylon stops sending email to an address once it hard bounces or is suppressed manually. Use these methods to check and clear suppressions.
+
+```ruby
+# Check whether a single address is suppressed
+suppressions = client.list_email_suppressions(email: 'user@example.com')
+
+if suppressions.size.zero?
+  puts 'not suppressed'
+else
+  suppression = suppressions.first
+  puts "#{suppression.email} suppressed (#{suppression.reason}) at #{suppression.created_at}"
+  puts suppression.bounce_details if suppression.bounce_details
+end
+
+# List suppressions, most recent first, using the API's cursor pagination
+page = client.list_email_suppressions(limit: 100)
+pagination = page._response.body['pagination']
+next_page = client.list_email_suppressions(cursor: pagination['cursor']) if pagination['has_next_page']
+
+# Remove a suppression so Pylon resumes sending to the address
+client.delete_email_suppression(suppression.id)
+```
+
 ## Error Handling
 
 The client will raise different types of errors based on the API response:
