Changelog
What changed in the calculators, formulas and reference data, and when, newest first. Each entry is a user-visible change taken from the project history; data snapshots such as margin tiers and contract specs carry their own dates on the pages that use them.

- Relationship wording is now one disclosure line in the footer and on the About page, covering every venue listed on the site; it replaces the earlier wording that named a single venue.
- New About and Changelog pages with contact, privacy and corrections information; Bybit and Hyperliquid tier presets sit beside the existing modes.
- Machine-readable data: leverage caps, CME contract specs, Hyperliquid margin tiers and Bybit BTCUSDT maintenance-margin tiers as JSON under /data/, each with a version, generation time and source.
- Liquidation price calculator: Bybit BTCUSDT maintenance-margin tier preset (fetched from Bybit's public risk-limit API) beside the existing auto and manual MMR, with the tier table and its check date.
- Methodology: full long and short liquidation formulas, how fees, funding and cross margin are handled, stale-data rule and field documentation for the data files.
- Home page: ROE with trading fees formula, a worked 5x ETH short example and matching FAQ entries.
- Answer-first introductions and question-matched FAQs on the calculator and Hyperliquid pages; Hyperliquid calculator title now leads with liquidation price, margin and PnL.
- Added the trading fee calculator (fees, builder fee, slippage, funding, break-even) and the pair trade calculator (long-short sizing, ratio PnL, per-leg and cross liquidation, net funding).
- Hyperliquid calculator fixes: PnL tab maker fee, funding sign for shorts, BTC as default asset, maintenance margin read from the margin tiers, warning above an asset's max leverage, price reload when the asset changes.
- Added the risk reward calculator and the Hyperliquid calculator (liquidation with margin tiers, fees with volume tiers and HYPE staking, PnL with funding).
