 ## Current Master
 
+## 3.13.5 2018-1-16
+
+- Estimating gas limit for simple ether sends now faster & cheaper, by avoiding VM usage on recipients with no code.
+- Add an extra px to address for Firefox clipping.
+- Fix Firefox scrollbar.
+- Open metamask popup for transaction confirmation before gas estimation finishes and add a loading screen over transaction confirmation.
+- Fix bug that prevented eth_signTypedData from signing bytes.
+- Further improve gas price estimation.
+
+## 3.13.4 2018-1-9
+
+- Remove recipient field if application initializes a tx with an empty string, or 0x, and tx data. Throw an error with the same condition, but without tx data.
+- Improve gas price suggestion to be closer to the lowest that will be accepted.
 - Throw an error if a application tries to submit a tx whose value is a decimal, and inform that it should be in wei.
 - Fix bug that prevented updating custom token details.
 - No longer mark long-pending transactions as failed, since we now have button to retry with higher gas.
 - Fix rounding error when specifying an ether amount that has too much precision.
+- Fix bug where incorrectly inputting seed phrase would prevent any future attempts from succeeding.
