v1.7.0 — World-class SDK Upgrade

What's New

Full Async Client

• All 16 resources now available on AsyncOilPriceAPI (was only 2: prices + historical)
• Async iter_pages() generator for memory-efficient pagination

New Features

• Webhook signature verification — verify_webhook_signature() with HMAC-SHA256 and constant-time comparison
• oilprice CLI — oilprice price BRENT_CRUDE_USD, oilprice historical, oilprice commodities with --json output
• Opt-in telemetry — enable_telemetry=True on both sync and async clients
• 429 auto-retry — honors Retry-After header (capped at 60s) instead of immediately raising

Bug Fixes

• Fixed version triple mismatch (single source in version.py)
• Fixed Python 3.8 syntax compatibility
• Fixed await response.json() crash in async client (httpx .json() is synchronous)
• Fixed get_current_price() connection leak
• Removed unused aiohttp from [async] extra

Developer Experience

• ValidationError, TimeoutError, ConfigurationError now exported from top-level
• Lint/mypy now blocking in CI
• Coverage enforcement gate (--cov-fail-under=50)
• mkdocs + mkdocstrings API reference
• Shared resource_validators.py to reduce sync/async duplication
