v1.8.0

Warning

Use v1.9.0 instead.

Windows Defender flags this build as Behavior:Win32/DefensiveEvasion.A!ml
and will quarantine it. The cause is pain's Windows shell integration: to
track a pane's working directory it wrote a startup script to the temp
directory and spawned the shell against it, including across the WSL
boundary. That is a fair thing for a behavioural classifier to object to.

The detection is a false positive — the binary is built by GitHub Actions
from the tagged source and no dependency changed from v1.7.0 — but the
behaviour it flagged was real, and v1.9.0 removes it.

• Fixed: every color rendered noticeably brighter and more washed out than
  the color it was supposed to be. Themes made this obvious — Ayu's greens
  arriving as pale mint — but it applied to the default palette and the
  app's own chrome just as much. The window is an sRGB-format surface, so
  the GPU applies gamma encoding to whatever is drawn; colors were being
  handed over already encoded and so got encoded a second time. Colors now
  match their published hex values.

  The window background also renders correctly at transparency levels
  below 1.0, where it was previously composited without being scaled by its
  own alpha and read brighter than the opaque one.

• Fixed: many standard keys did nothing. Home, End, Page Up,
  Page Down, Insert, Delete and F1–F12 had no encoding at all and
  were silently dropped. Shift+Tab sent a plain tab, so it moved forward
  through a form or completion menu instead of back. Modified cursor keys
  (Ctrl+Left, Shift+End, ...) lost their modifier. Alt was not sent as
  Meta, so readline's word-wise motions — Alt+B, Alt+F, Alt+D — did
  nothing. Application cursor mode was ignored, so arrow keys used the wrong
  form inside vim, less and anything else that enables it.

  Keyboard input is now the full xterm-compatible encoding rather than the
  handful of keys the first version implemented.

• The kitty keyboard protocol is now supported, which is what lets a program
  tell Shift+Enter, Ctrl+Enter and plain Enter apart. These are the
  same byte in the traditional encoding and cannot be distinguished in it at
  all; editors and CLI tools that offer Shift+Enter for a newline ask for
  this protocol to get it. Programs that don't ask are unaffected.

• Fixed, theme picker: clicking the filter box closed the dropdown, so the
  filter could not be used. The list also stopped at the first 100 of 600
  themes with a "keep typing" note at the bottom, and had two nested
  scrollbars, the visible one belonging to the wrong thing. The whole list
  now scrolls, filtering works, and it shows twelve themes at a time.

• Ctrl+Plus and Ctrl+Minus change the font size by a point, and Ctrl+0
  returns it to the default. The new size is saved, so it survives a
  restart.

  These chords previously did something else entirely: nothing had bound
  them, so the UI toolkit's own handler claimed them and scaled the app's
  menus and panels instead of the terminal font — which is what was leaving
  the right-click menus offset from the pointer afterwards.

• Fixed: the text cursor was partly transparent, so at any transparency
  setting below fully opaque the desktop showed through it. It is now a
  solid block with the character under it drawn in reverse video, which is
  what other terminals draw. The selection highlight had the same problem
  and keeps its blended appearance without being see-through.

• The title bar color is now configurable, in Settings or as
  appearance.title_bar_color. Its text color follows automatically, so a
  pale title bar gets dark text. Grouped panes still take their color from
  their group — that is the only way to tell groups apart.

• Keybindings are written with spaces instead of +: "ctrl shift e",
  "ctrl +", "ctrl -". It reads better, and it means + and - are
  writable as themselves rather than spelled out — a separator that is also
  a key on the keyboard can't represent that key. The space key is written
  space.

  Existing config files are unaffected: the older "ctrl+shift+e" form is
  still read.

• Fixed, Settings: the scroll bar overlapped the right edge of the controls
  beside it. It now has a margin of its own.
