 ## Current Master
 
+## 3.8.3 2017-7-6
+
+- Re-enable default token list.
+- Add origin header to dapp-bound requests to allow providers to throttle sites.
+- Fix bug that could sometimes resubmit a transaction that had been stalled due to low balance after balance was restored.
+
+## 3.8.2 2017-7-3
+
+- No longer show network loading indication on config screen, to allow selecting custom RPCs.
+- Visually indicate that network spinner is a menu.
+- Indicate what network is being searched for when disconnected.
+
+## 3.8.1 2017-6-30
+
+- Temporarily disabled loading popular tokens by default to improve performance.
+- Remove SEND token button until a better token sending form can be built, due to some precision issues.
+- Fix precision bug in token balances.
+- Cache token symbol and precisions to reduce network load.
+- Transpile some newer JavaScript, restores compatibility with some older browsers.
+
+## 3.8.0 2017-6-28
+
+- No longer stop rebroadcasting transactions
 - Add list of popular tokens held to the account detail view.
+- Add ability to add Tokens to token list.
 - Add a warning to JSON file import.
+- Add "send" link to token list, which goes to TokenFactory.
 - Fix bug where slowly mined txs would sometimes be incorrectly marked as failed.
 - Fix bug where badge count did not reflect personal_sign pending messages.
 - Seed word confirmation wording is now scarier.
 - Fix error for invalid seed words.
 - Prevent users from submitting two duplicate transactions by disabling submit.
+- Allow Dapps to specify gas price as hex string.
+- Add button for copying state logs to clipboard.
