 ## [Unreleased]
 
-## [3.4.0] - TBD
+## [3.4.0] - 2026-05-28
 
 This release upgrades the deployed PDPVerifier contract with data-set cleanup deposits and explicit piece-cleanup finalization. New data sets now hold a 0.1 FIL cleanup deposit that is returned to whoever completes cleanup after deletion, giving storage providers and permissionless cleanup callers a concrete incentive to clear on-chain piece state.
 
-The release notes are drafted before deployment. Final release date, implementation addresses, and verification links should be filled in after the Calibration and Mainnet rollouts execute.
-
-The active Mainnet and Calibnet proxies currently report `VERSION() == "3.2.0"`. The `v3.3.0` release was library-only and did not deploy a PDPVerifier implementation, so this rollout intentionally fast-forwards the deployed contract version from `3.2.0` to `3.4.0`.

 ### Deployed
 
+The implementation contracts were deployed from commit [`1370f49f9af958e4e3a1396377035685d55ffdba`](https://github.com/FilOzone/pdp/commit/1370f49f9af958e4e3a1396377035685d55ffdba). The `v3.4.0` release tag may point to a later documentation-only commit that finalizes these release notes.

 ### Breaking Changes
 - New data-set creation now requires a 0.1 FIL cleanup deposit. Callers of `createDataSet()` and callers that create a data set through `addPieces(NEW_DATA_SET_SENTINEL, ...)` must send at least `FIL_CLEANUP_DEPOSIT()` in `msg.value`; excess FIL is refunded.
