Emacs: dired-preview version 0.6.0
This is a simple package to automatically preview in a window the file at point in Dired buffers. Preview windows are closed when they are no longer relevant, while preview buffers are killed if they have not been used for other purposes beside previewing. The package provides several customisation options to control its behaviour.

Below are the release notes
Version 0.6.0 on 2025-07-18
This is a small release that provides quality-of-life refinements.
Optionally do not trigger a preview when entering the directory
The new user option dired-preview-trigger-on-start controls whether
a preview is produced automatically when (i) entering a directory
while (ii) the dired-preview-mode or its global counterpart is
enabled.
The default value is non-nil, which preserves the behaviour we have
always had of previewing outright. When set to nil, the preview does
not happen upon entering a directory and is triggered only after one
of the commands in denote-preview-trigger-commands is invoked.
I did this is in response to issue 31 by dasoju: https://github.com/protesilaos/dired-preview/issues/31.
Define which commands trigger a preview
The denote-preview-trigger-commands is now declared as a “user
option” rather than a generic variable, meaning that users are
encouraged to customise it (and it technically is available via the
Custom interface and related). Everything should otherwise work the
same as before.
The preview does not interfere with dired-dwim-target
Previous versions would make dired-dwim-target not return the
directory of the other window. Whereas we want the preview to not
influence how Dired behaves when copying or renaming files.
The bug was addressed in patch release 0.5.2.
Fixed a temporary bug in dired-preview-page-up
It was missing the macro we define to perform operations in the preview window.
Thanks to Alex Popescu for telling me that the command was not working. This was done in issue 28: https://github.com/protesilaos/dired-preview/issues/28.
The bug was addressed in patch release 0.5.1.
