+# v8.0.0
+## How to Upgrade
+**When upgrading to this version of hsd, you must pass `--chain-migrate=4`
+and `--wallet-migrate=7` when you run it for the first time.
+It is strongly recommended to back up your wallet before proceeding with the upgrade
+([#925](https://github.com/handshake-org/hsd/pull/925),
+ [#928](https://github.com/handshake-org/hsd/pull/928))**.
+
+## Notable Changes
+
+### Network
+
+**End Airdrop soft fork has been included. ([#927](https://github.com/handshake-org/hsd/pull/927))
+Miners who want to support the soft-fork need to start signalling with `airstop` bit.**
+
+### Wallet Changes
+
+#### Wallet HTTP API
+  - `POST /wallet/:id/zap` response object has a new property: `zapped: number`,
+    indicating the number of transactions that were zapped
+    ([#920](https://github.com/handshake-org/hsd/pull/920)).
+  - `GET /wallet/:id/name/:name` now accepts an `own` parameter and only returns
+    the namestate when the wallet owns the name
+    ([#922](https://github.com/handshake-org/hsd/pull/922)).
+  - Introduce admin `POST /recalculate-balances`, useful if the post-migration
+    recalculation was not triggered and wallet balances are not correct
+    ([#926](https://github.com/handshake-org/hsd/pull/926)).
+  - The TX creation HTTP Endpoints now supports new values for the `selection`
+    property. These new strategies use database iterators instead of loading all
+    coins into RAM ([#928](https://github.com/handshake-org/hsd/pull/928)).
+    - `db-value` - This is a database alternative to `value` and new default.
+    - `db-age` - A database alternative `age`.
+    - `db-all` - A database alternative `all`.
+    - `db-sweepdust` - Select smallest coins first.
+      - Add `sweepdustMinValue` option for TX creation endpoints, default 1.
+
+#### Wallet/WalletDB API
+  - `Wallet.zap` now returns the number of transactions zapped instead of their hashes
+    ([#920](https://github.com/handshake-org/hsd/pull/920)).
+
+### hs-client Wallet
+  - `getName` now accepts an `options` object with an `own` property
+    ([#922](https://github.com/handshake-org/hsd/pull/922)).
