2022-06-21 i3lock 2.14.1
• unlock indicator: display only caps lock and num lock,
not all modifiers like shift (which can leak information
about your password to bystanders)
2022-05-28 i3lock 2.14
• Change default background color to #a3a3a3
See for extensive
discussion and rationale for this change.
• Recommend using xss-lock to start i3lock in the README
and i3lock.1 man page. xss-lock is the best way to ensure
your screen truly is locked before your computer suspends.
• Display modifier key warning before unlocking, too,
not just on failed attempts like before.
• Switch build system from autotools to meson.
2020-10-27 i3lock 2.13

• Display an error when backspace is pressed without any input

2017-06-21 i3lock 2.9.1
• Fix version number mechanism (for --version)

it solves:

• i3lock.1: use signal names without SIG prefix
• Removed obsolete inactivity timeout

entered while authenticating

• Add Enter on C-m
• Change input slices to be exactly pi/3 in size instead of slightly more
• Fix covering of composited notifications using the XComposite extension

• Indicate that the --inactivity-timeout option takes an argument. (Thanks
Kenneth Lyons)
• fix pam_securetty: set PAM_TTY to getenv("DISPLAY")
• Eat XKB_KEY_Delete and XKB_KEY_KP_Delete (Thanks bebehei)
• Show unlock indicator if password was entered during PAM verification

This helps us get rid of all code that directly uses libX11
• Use cairo_status_to_string for descriptive errors.
• Add `-e` option to not validate empty password.

• Discard half-entered passwd after some inactivity
• Ignore empty passwd after repeated Enter keypress
• Scale the unlock indicator (for retina displays)
2013-06-09 i3lock 2.5

This makes input handling much better for many edge cases.

• Bugfix: Copy the color depth from parent (root) window instead of
hardcoding a depth of 24

copying contents on every expose event
