Introduced depositVariableOnly and settleVariableOnly on the /v2/coins endpoint. These fields list networks that only support variable rate shifts as a deposit or settle, using the same shape as fixedOnly: false when no network applies, otherwise an array of networks.
Marked variableOnly as deprecated on the /v2/coins endpoint. It remains the union of depositVariableOnly and settleVariableOnly. Use the split fields instead so a network that is variable only on one side is not treated as variable only on both.
SideShift Pay and its checkout endpoints (POST /v2/checkout and GET /v2/checkout/{checkoutId}) are deprecated and their documentation has been removed. Existing integrations should migrate to the SideShift API shift endpoints directly.
Legacy Widget Embed is deprecated. New integrations should use the SideShift API directly. Existing widget embeds remain operational, but the embed generator is no longer available.
