+## Version 1.4.0
+
+The `rippled` 1.4.0 release introduces several improvements and new features, including support for deleting accounts, improved peer slot management, improved CI integration and package building and support for [C++17](https://en.wikipedia.org/wiki/C%2B%2B17) and [Boost 1.71](https://www.boost.org/users/history/version_1_71_0.html). Finally, this release removes the code for the `SHAMapV2` amendment which failed to gain majority support and has been obsoleted by other improvements.
+
+**New and Updated Features**
+- The `DeletableAccounts` amendment which, if enabled, will make it possible for users to delete unused or unneeded accounts, recovering the account's reserve.
+- Support for improved management of peer slots and the ability to add and removed reserved connections without requiring a restart of the server.
+- Tracking and reporting of cumulative and instantaneous peer bandwidth usage. 
+- Preliminary support for post-processing historical shards after downloading to index their contents.
+- Reporting the master public key alongside the ephemeral public key in the `validation` stream [subscriptions](https://xrpl.org/subscribe.html).
+- Reporting consensus phase changes in the `server` stream [subscription](https://xrpl.org/subscribe.html).
+
+**Bug Fixes**
+- The `fixPayChanRecipientOwnerDir` amendment which corrects a minor technical flaw that would cause a payment channel to not appear in the recipient's owner directory, which made it unnecessarily difficult for users to enumerate all their payment channels.
+- The `fixCheckThreading` amendment which corrects a minor technical flaw that caused checks to not be properly threaded against the account of the check's recipient.
+- Respect the `ssl_verify` configuration option in the `SSLHTTPDownloader` and `HTTPClient` classes.
+- Properly update the `server_state` when a server detects a disagreement between itself and the network.
+- Allow Ed25519 keys to be used with the `channel_authorize` command.
+
