+# Release 3.3.7 - (July 3, 2019)
+
+ * The AppImage Linux x86_64 binary and the Windows setup.exe
+   (so now all Windows binaries) are now built reproducibly.
+ * Bump fee (RBF) improvements:
+   Implemented a new fee-bump strategy that can add new inputs,
+   so now any tx can be fee-bumped (d0a4366). The old strategy
+   was to decrease the value of outputs (starting with change).
+   We will now try the new strategy first, and only use the old
+   as a fallback (needed e.g. when spending "Max").
+ * CoinChooser improvements:
+   - more likely to construct txs without change (when possible)
+   - less likely to construct txs with really small change (e864fa5)
+   - will now only spend negative effective value coins when
+     beneficial for privacy (cb69aa8)
+ * fix long-standing bug that broke wallets with >65k addresses (#5366)
+ * Windows binaries: we now build the PyInstaller boot loader ourselves,
+   as this seems to reduce anti-virus false positives (1d0f679)
+ * Android: (fix) BIP70 payment requests could not be paid (#5376)
+ * Android: allow copy-pasting partial transactions from/to clipboard
+ * Fix a performance regression for large wallets (c6a54f0)
+ * Qt: fix some high DPI issues related to text fields (37809be)
+ * Trezor:
+   - allow bypassing "too old firmware" error (#5391)
+   - use only the Bridge to scan devices if it is available (#5420)
+ * hw wallets: (known issue) on Win10-1903, some hw devices
+   (that also have U2F functionality) can only be detected with
+   Administrator privileges. (see #5420 and #5437)
+   A workaround is to run as Admin, or for Trezor to install the Bridge.
+ * Several other minor bugfixes and usability improvements.
+

 # Release 3.3.6 - (May 16, 2019)
 
  * qt: fix crash during 2FA wallet creation (#5334)
