 # @mrgnlabs/marginfi-client-v2
 
+## 5.0.0
+
+### Major Changes
+
+- 9215e8f: # Major SDK Update 🚀
+
+  This release brings **significant improvements**, optimizations, and new features to the SDK—focusing on transaction builders, processing pipelines, and staked collateral support. **Please update your implementation** if you are using any transaction builders, as there are **context and syntax changes** (see provided JSDoc documentation for each function).
+
+  ***
+
+  ## 🔄 Transaction Builder Enhancements
+
+  - **Updated Builder Syntax**
+
+    - `account.make<Action>Tx` functions now include minor context and syntax changes to allow for greater customization.
+    - **Flashloan Builders:**
+      - Builders such as `makeLooperTx` and `makeRepayWithCollateralTx` have been revamped to optimize transaction size and prevent instruction overflow.
+
+  - **Action Required:**
+    - **Update Your Code:** Ensure you update your transaction builder usage to match the new syntax.
+
+  ***
+
+  ## 💼 Extended Solana Transaction Types
+
+  All builders now return a `SolanaTransaction`, an extension of the standard Solana web3.js `Transaction` and `VersionedTransaction`. This extended type includes:
+
+  - **`type`:** Enum representing the available SDK actions.
+  - **`signers`:** An array of signers required for the transaction.
+  - **`addressLookupTables`:** Lookup tables used during transaction signing and decompilation.
+  - **`unitsConsumed`:** A value (default or dynamically updated) to help compute the priority fee, ensuring an optimal landing rate.
+
+  **Benefits:**
+
+  - Improved transaction inspection and decompilation.
+  - Enhanced integration with custom transaction processing pipelines.
+
+  ***
+
+  ## ⚙️ Advanced Transaction Processing Pipeline
+
+  The new processing flow is modular and highly optimized for both standard and flashloan transactions. There are two ways to access the pipeline:
+
+  1. **Within MarginfiAccountWrapper Actions:**
+
+     - All account actions (e.g., deposit, withdraw, borrow) include the processing pipeline as part of their internal logic.
+
+  2. **Standalone from the Client:**
+     - Use the standalone function `processTransactions` or leverage prefilled configuration via `client.processTransactions`.
+
+  ### Pipeline Features
+
+  1. **Simulate to Fetch Compute Unit (CU) Limits:**
+
+     - The transaction is simulated (ignoring the blockhash) to determine the required compute unit size.
+     - The CU limit instruction is then updated accordingly.
+
+  2. **Transaction Formatting via `formatTransactions`:**
+
+     - **Heavily Optimized for Flashloans:**
+       - `formatTransactions` is tailored for flashloan transactions to ensure maximum throughput and reliability.
+     - **Ad-hoc Integration:**
+       - This step can be integrated ad-hoc into your existing transaction processing logic.
+     - **Updates Blockhash:**
+       - Ensures the transaction uses the most recent blockhash.
+     - **Jito Bundles Support:**
+       - Appends a bundle tip if the transaction is destined for a jito bundle.
+       - Measures transaction size to decide whether the bundle tip should be appended inline or sent as a separate transaction.
+       - _Note:_ Flashloan transactions will always have the bundle tip appended as a separate transaction due to fixed instruction index constraints.
+     - **Accurate Priority Fee Assignment:**
+       - Uses the computed CU size from simulation to assign a precise priority fee when sending over RPC.
+     - **Optional Transaction Tagging:**
+       - If `addTransactionTags` is enabled, a tag corresponding to the transaction action is added for easier parsing.
+
+  3. **Pre-Execution Simulation:**
+
+     - An additional simulation step is performed to validate the transaction before waiting for it to land.
+
+  4. **Flexible Execution:**
+     - Transactions are routed through jito bundles or RPC based on your configuration, with built-in fallbacks for optimal execution.
+     - Special routing logic is applied for flashloan transactions.
+
+  ***
+
+  ## ⭐ Additional Enhancements
+
+  - **Enhanced Flashloan Support** 🏦
+
+    - Improved flashloan handling and execution.
+    - More efficient processing of flashloan transactions.
+
+  - **More Configurable SDK Functions** ⚙️
+
+    - New options to fine-tune SDK behavior.
+    - Increased flexibility for integrators.
+
+  - **Optimized Flashloan Transaction Processing** ⚡
+
+    - Reduced overhead.
+    - Improved speed and reliability.
+
+  - **Full JSDoc Support** 📖
+
+    - Comprehensive documentation for improved developer experience.
+    - Enhanced type safety and inline guidance.
+
+  - **Staked Collateral Support** 🔐
+
+    - **New Functionality:**
+      - The SDK now includes `makeAddPermissionlessStakedBankIx` within the group class to create new staked banks permissionlessly.
+      - Pricing functions have been updated to handle this new staked collateral type.
+    - **Future Expansion:**
+      - This functionality will be further expanded in future releases.
+      - For a full implementation (including uploading metadata and creating single SPL stake pools), please refer to:
+        `mrgn-ts/apps/marginfi-v2-ui/src/pages/staked-assets/create.tsx`.
+
+  - **General Improvements:**
+    - Resolved multiple issues from previous versions.
+    - Overall performance optimizations and stability improvements.
+
+  ***
+
+  Feel free to reach out with any questions or feedback regarding these changes. Happy coding!
