# Transmission 4.0.4

This is a bugfix-only release. Everyone's feedback on 4.0.x has been very helpful -- thanks for all the suggestions, bug reports, and pull requests!


## What's New in 4.0.4

### All Platforms

* Fixed bug in sending torrent metadata to peers. ([#5460](https://github.com/transmission/transmission/pull/5460))
* Avoid unnecessary heap memory allocations. ([#5520](https://github.com/transmission/transmission/pull/5520), [#5527](https://github.com/transmission/transmission/pull/5527))
* Fixed filename collision edge case when renaming files. ([#5563](https://github.com/transmission/transmission/pull/5563))
* Fixed locale errors that broke number rounding when displaying statistics, e.g. upload / download ratios. ([#5587](https://github.com/transmission/transmission/pull/5587))
* Always use a fixed-length key query in tracker announces. This isn't required by the [spec](https://www.bittorrent.org/beps/bep_0007.html), but some trackers rely on that fixed length because it's common practice by other BitTorrent clients. ([#5652](https://github.com/transmission/transmission/pull/5652))
* Fixed potential Windows crash when [getstdhandle()](https://learn.microsoft.com/en-us/windows/console/getstdhandle) returns `NULL`. ([#5675](https://github.com/transmission/transmission/pull/5675))
* Fixed `4.0.0` bug where the port numbers in LDP announces are sometimes malformed. ([#5825](https://github.com/transmission/transmission/pull/5825))
* Fixed a bug that prevented editing the query part of a tracker URL. ([#5871](https://github.com/transmission/transmission/pull/5871))
* Fixed a bug where Transmission may not announce LPD on its listening interface. ([#5896](https://github.com/transmission/transmission/pull/5896))
* Made small performance improvements in libtransmission. ([#5715](https://github.com/transmission/transmission/pull/5715))

### macOS Client

* Updated code that had been using deprecated API. ([#5633](https://github.com/transmission/transmission/pull/5633))

### Qt Client

* Fixed torrent name rendering when showing magnet links in compact view. ([#5491](https://github.com/transmission/transmission/pull/5491))
* Fixed bug that broke the "Move torrent file to trash" setting. ([#5505](https://github.com/transmission/transmission/pull/5505))
* Fixed Qt 6.4 deprecation warning. ([#5552](https://github.com/transmission/transmission/pull/5552))
* Fixed poor resolution of Qt application icon. ([#5570](https://github.com/transmission/transmission/pull/5570))

### GTK Client

* Fixed missing 'Remove torrent' tooltip. ([#5777](https://github.com/transmission/transmission/pull/5777))

### Web Client

* Don't show `null` as a tier name in the inspector's tier list. ([#5462](https://github.com/transmission/transmission/pull/5462))
* Fixed truncated play / pause icons. ([#5771](https://github.com/transmission/transmission/pull/5771))
* Fixed overflow when rendering peer lists and made speed indicators honor `prefers-color-scheme` media queries. ([#5814](https://github.com/transmission/transmission/pull/5814))
* Made the main menu accessible even on smaller displays. ([#5827](https://github.com/transmission/transmission/pull/5827))

### transmission-cli

* Fixed "no such file or directory" warning when adding a magnet link. ([#5426](https://github.com/transmission/transmission/pull/5426))
* Fixed bug that caused the wrong decimal separator to be used in some locales. ([#5444](https://github.com/transmission/transmission/pull/5444))

### transmission-remote

* Fixed display bug that failed to show some torrent labels. ([#5572](https://github.com/transmission/transmission/pull/5572))

### Everything Else

* Ran all PNG files through lossless compressors to make them smaller. ([#5586](https://github.com/transmission/transmission/pull/5586))
* Fixed potential build issue when compiling on macOS with gcc. ([#5632](https://github.com/transmission/transmission/pull/5632))
