+# Changelog
+
+All notable changes to the `ipwhois` gem will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [1.2.0] - 2026-05-12
+
+### Added
+
+- Initial public release of the `ipwhois` gem.
+- `Ipwhois::Client#lookup` — single IP lookup (IPv4 / IPv6, or current IP).
+- `Ipwhois::Client#bulk_lookup` — up to 100 IPs in a single GET request
+  (paid plan).
+- Free plan (no API key, `ipwho.is`) and paid plan (with API key,
+  `ipwhois.pro`) served by the same `Client` class.
+- HTTPS by default; `ssl: false` constructor option to fall back to HTTP.
+- Localisation (`:lang`), field filtering (`:fields`), threat detection
+  (`:security`), rate-limit info (`:rate`).
+- Fluent client-wide defaults: `set_language`, `set_fields`, `set_security`,
+  `set_rate`, `set_timeout`, `set_connect_timeout`, `set_user_agent` — each
+  returns `self` and is chainable.
+- **The library never raises.** All errors — invalid input, network failure,
+  API-level errors (bad IP, bad key, rate limit, …) — are returned in the
+  response hash with `'success' => false` and a `'message'`. HTTP error
+  responses are additionally enriched with `'http_status'`, and HTTP 429
+  responses on the free plan with `'retry_after'`.
+- Every error response carries an `'error_type'` field: one of `'api'`,
+  `'network'`, or `'invalid_argument'`, so callers can branch on the failure
+  category with a single `info['error_type']` check.
+- Minitest test suite covering URL construction, IPv6 path encoding, and
+  input validation. No real HTTP request is sent — the suite runs anywhere
+  without an API key or network access.
+- No runtime dependencies — uses only the Ruby stdlib (`net/http`, `uri`,
+  `json`, `openssl`).
+- Ruby `>= 3.0` requirement.
