+## Notable Changes
+
+- **Asset Unlock Transactions (Platform Transfer)**
+    - Introduces a new fork `withdrawals` that changes consensus rules.
+    - **Validation Logic Update:**
+        - Allows using all **24 active quorums** and the most recent inactive quorum.
+        - Previous versions may refuse withdrawals with `bad-assetunlock-not-active-quorum` even if the quorum is active.
+    - **Withdrawal Limits Increased:**
+        - Flat **2000 Dash** per **576 latest blocks**.
+- **Increased Minimum Protocol Version**
+    - The minimum protocol version has been increased to **70216**.
+    - Masternode minimum protocol version has increased to **70235**.
+
+## Compatibility
+
+- **Dark Mode Appearance**
+    - Dash Core changes appearance when macOS "dark mode" is activated.
+
+- **glibc Requirement**
+    - The minimum required glibc to run Dash Core is now **2.31**. This means that **RHEL 8** and **Ubuntu 18.04 (Bionic)** are no longer supported.
+
+
+## Updated RPCs
+
+- **`getpeerinfo` Changes**
+    - `getpeerinfo` no longer returns the following fields: `addnode` and `whitelisted`, which were previously deprecated in v21.
+        - Instead of `addnode`, the `connection_type` field returns `manual`.
+        - Instead of `whitelisted`, the `permissions` field indicates if the peer has special privileges.
+    - *(#20755)*
+
+- **`getblockfrompeer` Parameter Renaming**
+    - The named argument `block_hash` has been renamed to `blockhash` to align with the rest of the codebase.
+    - **Breaking Change:** If using named parameters, ensure to update them accordingly.
+    - *(#6149)*
+
+- **`coinjoin stop` Error Handling**
+    - `coinjoin stop` will now return an error if there is no CoinJoin mixing session to stop.
+
+- **`getcoinjoininfo` Adjustments**
+    - `getcoinjoininfo` will no longer report `keys_left` and will not incorrectly warn about keypool depletion with descriptor wallets.
+
+- **`creditOutputs` Format Change**
+    - `creditOutputs` entries in various RPCs that output transaction JSON are now shown as objects instead of strings.
+
+- **`quorum dkgsimerror` Argument Update**
+    - `quorum dkgsimerror` will no longer accept a decimal value between 0 and 1 for the `rate` argument.
+    - It will now expect an integer between **0** to **100**.
+
+- **Deprecated `protx *_hpmn` RPC Endpoints**
+    - Deprecated `protx *_hpmn` RPC entry points have been dropped in favor of `protx *_evo`.
+    - **Removed Endpoints:**
+        - `protx register_fund_hpmn`
+        - `protx register_hpmn`
+        - `protx register_prepare_hpmn`
+        - `protx update_service_hpmn`
+
+## Command-line Options
+
+### Changes in Existing Command-line Options
+
+- **`-walletnotify=<cmd>` Enhancements**
+    - Introduces new format options `%h` and `%b`.
+        - `%b`: Replaced by the hash of the block including the transaction (set to `'unconfirmed'` if the transaction is not included).
+        - `%h`: Replaced by the block height (**-1** if not included).
+
+- **`-maxuploadtarget` Format Update**
+    - Now allows human-readable byte units `[k|K|m|M|g|G|t|T]`.
+        - **Example:** `-maxuploadtarget=500g`.
+        - **Constraints:** No whitespace, `+`, `-`, or fractions allowed.
+        - **Default:** `M` if no suffix is provided.
+
+## New Functionality
+
+- **`coinjoinsalt` RPC Command**
+    - Allows manipulation of a CoinJoin salt stored in a wallet.
+        - `coinjoinsalt get`: Fetches an existing salt.
+        - `coinjoinsalt set`: Allows setting a custom salt.
+        - `coinjoinsalt generate`: Sets a random hash as the new salt.
+
+- **LLMQ Type Enhancement**
+    - **LLMQ_50_60** is enabled for **Devnet** networks.
+    - Necessary for testing on a large Devnet.
+
+## P2P and Network Changes
+
+- **Improved Onion Connectivity**
+    - Nodes with onion connectivity will attempt to maintain at least **two outbound onion connections** and will protect these connections from eviction.
+    - **Benefit:** Ensures nodes capable of accessing the onion network maintain a few onion connections, allowing network messages to propagate even if non-onion IPv4 traffic is blocked.
+    - **Security Enhancement:** Enables P2P encryption for these peers.
+    - *(#6147)*
+
+- **DSQ Message Broadcast Update**
+    - Starting in protocol version **70234**, DSQ messages are broadcast using the inventory system instead of relaying to all connected peers.
+    - **Benefit:** Reduces bandwidth needs for all nodes, especially noticeable on highly connected masternodes.
+    - *(#6148)*
+
+- **Compressed Block Headers Request Limit**
+    - Starting in protocol version **70235**, The maximum number of compressed block headers that can be requested at once has been increased from **2000** to **8000**.
+    - **Applies to:** Compressed block headers only.
+    - **Benefit:** Potential for improved header sync performance.
+
+- **Multi-Network Connectivity Enhancement**
+    - Nodes with multiple reachable networks will actively try to maintain at least one outbound connection to each network.
+    - **Benefits:**
+        - Improves resistance to eclipse attacks.
+        - Enhances network-level resistance to partition attacks.
+    - **User Impact:** Users no longer need to perform active measures to ensure connections to multiple enabled networks.
+
+- **BIP324 Encrypted Communication (Experimental)**
+    - Dash Core now experimentally implements [BIP324](https://github.com/bitcoin/bips/blob/master/bip-0324.mediawiki), introducing encrypted communication for P2P network traffic.
+    - **Opt-In Adoption**
+      - **Enable Encryption:** Users can opt-in to use BIP324 by adding the `-v2transport=1` flag to their Dash Core configuration.
+      - **Default Behavior:** Encryption is **disabled by default** as this is currently experimental.
+    - **Benefits**
+      - **Enhanced Privacy:** Encrypts P2P messages for v2 connections, reducing the risk of traffic analysis and eavesdropping.
+      - **Improved Security:** Protects against certain types of network attacks by ensuring that communication between nodes is confidential and tamper-proof.
+    - **Limitations and Considerations**
+      - **Compatibility:** Encrypted connections may only be established between nodes that have BIP324 enabled. Nodes without encryption support will continue to communicate over unencrypted channels.
+    - **Status and Future Plans**
+      - **Experimental Phase:** This feature is currently in an experimental phase. Users are encouraged to test and provide feedback to ensure stability.
+      - **Future Development:** BIP324 will likely be enabled by default in the next minor version, v22.1.0.
+
+
+## Devnet Breaking Changes
+
+- **Hardfork Activation Changes**
+    - `BRR` (`realloc`), `DIP0020`, `DIP0024`, `V19`, `V20`, and `MN_R` hardforks are now activated at **block 2** instead of block **300** on devnets.
+    - **Implications:**
+        - Breaking change.
+        - Inability to sync on devnets created with earlier Dash Core versions and vice versa.
+
+## Tests
+
+- **Regtest Network Softfork Activation Heights**
+    - For the `regtest` network, the activation heights of several softforks have been set to **block height 1**.
+    - **Customization:** Can be changed using the runtime setting `-testactivationheight=name@height`.
+    - *(dash#6214)*
+
+## Statistics
+
+### New Features
+
+- **Statsd Client Enhancements**
+    - Supports queueing and batching messages.
+        - **Benefits:**
+            - Reduces the number of packets.
+            - Lowers the rate at which messages are sent to the Statsd daemon.
+
+- **Batch Configuration Options**
+    - **Maximum Batch Size:**
+        - Adjustable using `-statsbatchsize` (in bytes).
+        - **Default:** **1KiB**.
+    - **Batch Send Frequency:**
+        - Adjustable using `-statsduration` (in milliseconds).
+        - **Default:** **1 second**.
+        - **Note:** `-statsduration` does not affect `-statsperiod`, which dictates how frequently some stats are *collected*.
+
+### Deprecations
+
+- **Deprecation of `-platform-user`**
+    - `-platform-user` is deprecated in favor of the whitelist feature.
+    - In releases **22.x** of Dash Core, it has been renamed to `-deprecated-platform-user`.
+    - It will be removed in version **23.x**.
+
+- **`-statsenabled` Deprecation**
+    - Now implied by the presence of `-statshost`.
+    - It will be removed in version **23.x**.
+
+- **`-statshostname` Replacement**
+    - Deprecated and replaced with `-statssuffix` for better representation of the argument's purpose.
+    - **Behavior:** Behave identically to each other.
+    - It will be removed in version **23.x**.
+
+- **`-statsns` Replacement**
+    - Deprecated and replaced with `-statsprefix` for better representation of the argument's purpose.
+    - **Behavior:** `-statsprefix` enforces the usage of a delimiter between the prefix and key.
+    - It will be removed in version **23.x**.
+
+## GUI Changes
+
+- **RPC Server Functionality Option**
+    - A new option has been added to the "Main" tab in "Options" that allows users to enable RPC server functionality.
