# 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.
