Potential breaking change
[FIX] Price index names for USDC-related indices changed from ADA-USDC-DERIBIT-INDEX to our standard ADA_USDC-DERIBIT-INDEX names, also *-VIX indices changed to *-DVOL
Other changes
[API] [New] Added `private/toggle_portfolio_margining method` (note: it existed earlier but was designed only for internal use) Added `dry_run` parameter to only check the effect of toggling PM - it skips risk checks (returns portfolio change even if otherwise would return not_enough_funds error)
[API] [Change] added `interest_value` field to `public/ticker`, `private/get_position`, `private/get_positions` responses and notifications of `incremental_ticker.{instrument_name}`, `ticker.{instrument_name}.{interval}`, and `user.changes.*` (in positions) notifications for perpetual instruments.
[API] [MinorChange] `public/get_instrumets` now returns instruments pre-sorted by expiration date and kind (futures before options)
