 # @evolution-sdk/devnet
 
+## 1.1.7
+
+### Patch Changes
+
+- [#109](https://github.com/IntersectMBO/evolution-sdk/pull/109) [`0730f23`](https://github.com/IntersectMBO/evolution-sdk/commit/0730f2353490ff1fa75743cccc0d05b33cff1b23) Thanks [@solidsnakedev](https://github.com/solidsnakedev)! - ### TxBuilder setValidity API
+
+  Add `setValidity()` method to TxBuilder for setting transaction validity intervals:
+
+  ```ts
+  client.newTx()
+    .setValidity({
+      from: Date.now(),           // Valid after this Unix time (optional)
+      to: Date.now() + 300_000    // Expires after this Unix time (optional)
+    })
+    .payToAddress({ ... })
+    .build()
+  ```
+
+  - Times are provided as Unix milliseconds and converted to slots during transaction assembly
+  - At least one of `from` or `to` must be specified
+  - Validates that `from < to` when both are provided
+
+  ### slotConfig support for devnets
+
+  Add `slotConfig` parameter to `createClient()` for custom slot configurations:
+
+  ```ts
+  const slotConfig = Cluster.getSlotConfig(devnetCluster)
+  const client = createClient({
+    network: 0,
+    slotConfig,  // Custom slot config for devnet
+    provider: { ... },
+    wallet: { ... }
+  })
+  ```
+
+  Priority chain for slot config resolution:
+  1. `BuildOptions.slotConfig` (per-transaction override)
+  2. `TxBuilderConfig.slotConfig` (client default)
+  3. `SLOT_CONFIG_NETWORK[network]` (hardcoded fallback)
+
+  ### Cluster.getSlotConfig helper
+
+  Add `getSlotConfig()` helper to derive slot configuration from devnet cluster genesis:
+
+  ```ts
+  const slotConfig = Cluster.getSlotConfig(cluster)
+  // Returns: { zeroTime, zeroSlot, slotLength }
+  ```
+

 # @evolution-sdk/evolution
 
+## 0.3.7
+
+### Patch Changes
+
+- [#112](https://github.com/IntersectMBO/evolution-sdk/pull/112) [`c59507e`](https://github.com/IntersectMBO/evolution-sdk/commit/c59507eafd942cd5bce1d3608c9c3e9c99a4cac8) Thanks [@solidsnakedev](https://github.com/solidsnakedev)! - Add transaction chaining support via `SignBuilder.chainResult()`
+  - Add `chainResult()` method to `SignBuilder` for building dependent transactions
+  - Returns `ChainResult` with `consumed`, `available` UTxOs and pre-computed `txHash`
+  - Lazy evaluation with memoization - computed on first call, cached for subsequent calls
+  - Add `signAndSubmit()` convenience method combining sign and submit in one call
+  - Remove redundant `chain()`, `chainEffect()`, `chainEither()` methods from TransactionBuilder
+
+- [#110](https://github.com/IntersectMBO/evolution-sdk/pull/110) [`9ddc79d`](https://github.com/IntersectMBO/evolution-sdk/commit/9ddc79dbc9b6667b3f2981dd06875878d9ad14f5) Thanks [@solidsnakedev](https://github.com/solidsnakedev)! - ### Native Scripts & Multi-Sig Support
+  - **`addSigner` operation**: Add required signers to transactions for multi-sig and script validation
+  - **Native script minting**: Full support for `ScriptAll`, `ScriptAny`, `ScriptNOfK`, `InvalidBefore`, `InvalidHereafter`
+  - **Reference scripts**: Use native scripts via `readFrom` instead of attaching them to transactions
+  - **Multi-sig spending**: Spend from native script addresses with multi-party signing
+  - **Improved fee calculation**: Accurate fee estimation for transactions with native scripts and reference scripts
+
+  ### API Changes
+  - `UTxO.scriptRef` type changed from `ScriptRef` to `Script` for better type safety
+  - `PayToAddressParams.scriptRef` renamed to `script` for consistency
+  - Wallet `signTx` now accepts `referenceUtxos` context for native script signer detection
+  - Client `signTx` auto-fetches reference UTxOs when signing transactions with reference inputs
+
