Integration-Relevant Changes

Version or source note	Area	Change
`stake-for-fee` `0.1.1`	Program	`claim_fee` behavior changed so users can partially claim only the quote token side; the base/stake token side is automatically restaked.
SDK changelog `1.0.10`	TypeScript SDK	Removed `@solana-developers/helpers` dependency and replaced `@mercurial-finance/dynamic-amm-sdk` with `@meteora-ag/dynamic-amm-sdk`.
SDK changelog `1.0.9`	TypeScript SDK	Moved `@mercurial-finance/dynamic-amm-sdk` from dev dependency to dependency in the historical package lineage.
SDK changelog `common` `0.0.1`	Rust helpers	Added PDA helper functions to derive Stake2Earn vault, top staker list, full balance list, and event authority keys.
SDK changelog `1.0.1`	TypeScript SDK	Refactored `findLargestStakerNotInTopListFromFullBalanceList` and `findReplaceableTopStaker`.
Program source	Admin flows	`update_seconds_to_full_unlock` requires the immediately preceding instruction to be `claim_fee_crank` for the same vault and program.
Program source	Events	User and admin flows emit Anchor events through Event CPI.
Live production API	API	Production exposes `/analytics/all`, `/vault/all`, `/vault/filter`, and `/vault/{vault_address}`.

Documentation Notes

Date	Change
2026-05-22	Rebuilt the Stake2Earn developer guide around program accounts, instructions, events, errors, TypeScript SDK, Rust integration, API overview, and changelog pages.
2026-05-22	Replaced legacy long-form TypeScript script page with focused SDK getting-started, examples, and reference pages.
2026-05-22	Replaced legacy CPI examples page with Rust library and CPI integration pages based on the local Rust interface source.
2026-05-22	Updated the checked-in API spec to resolve the production vault-detail schema reference with observed production response fields.

Gaps To Watch

Gap	Impact
No high-level Rust SDK in inspected source	Rust integrations should use `stake_for_fee_interface`, `common` PDA helpers, and custom account fetching/parsing.
No TypeScript high-level admin builders	`claim_fee_crank` and admin update flows require low-level Anchor program usage or custom builders.
Production OpenAPI omits `VaultDetailWithLeaderboard` from live components	The docs include a local resolved schema, but integrators should still test API responses against the live host.
