Version 2.0.0 on 2023-11-27
═══════════════════════════

Deprecated several user options that changed colours
────────────────────────────────────────────────────

  The following user options are deprecated in favour of palette
  overrides (more in the following section):

  • `standard-themes-mode-line-accented'
  • `standard-themes-links'
  • `standard-themes-region'
  • `standard-themes-fringes'

  In the same spirit, the user option `standard-themes-prompts' no
  longer affects colours.


All colour-related tweaks are done via palette overrides
────────────────────────────────────────────────────────

  In previous versions of the themes, we provided certain hardcoded
  colour variations, such as for an "accented" mode line and more
  "intense" fringes. We no longer do so, in favour of a more flexible
  approach that empowers the user to pick the exact colour they like.

  The Standard themes provide the means to override every entry in their
  palette. Each palette defines named faces (such as what is the exact
  hexademical Red-Green-Blue value of `blue-warmer') as well as semantic
  colour mappings (like `bg-mode-line-active'). Users can configure
  either the `standard-themes-common-palette-overrides' or the
  theme-specific ones, `standard-dark-palette-overrides',
  `standard-light-palette-overrides'.

  Refer to the manual for how this can be done:
  
<https://protesilaos.com/emacs/standard-themes#h:34fe0582-960b-45dc-af5d-23c8f3e9d724>.
  And/or use the commands to preview the palette:
  `standard-themes-preview-colors',
  `standard-themes-preview-colors-current'. Below is a sample:

  ┌────
  │ (setq standard-themes-common-palette-overrides
  │       '((cursor red-warmer)
  │     (bg-mode-line-active bg-blue-subtle)))
  └────

  [ This is the same functionality found in my `modus-themes' and
    `ef-themes'. Modus has the most palette entries and widest package
    support due to its maximalist scope. ]


The `standard-themes-prompts' accept any typographic weight
───────────────────────────────────────────────────────────

  This user option applies to prompt texts of all sorts, such as the
  minibuffer and command-line shells. It now accepts any supported
  typographic weight as part of its value. The list of weights are
  recorded in the documentation of the variable
  `standard-themes-weights' as well as the manual.


Headings have more semantic colour mappings associated with them
────────────────────────────────────────────────────────────────

  Apart from the foreground, each heading level from 0 to 8 now has a
  background and an overline. These new palette entries are set to the
  `unspecified' value, meaning that they do not have any visual effect.
  Users can set them to a colour via palette overrides to have headings
  with a background and/or an overline (per heading level).

  Building on the previous sample code with the overrides:

  ┌────
  │ (setq standard-themes-common-palette-overrides
  │       '((cursor red-warmer)
  │     (bg-mode-line-active bg-blue-subtle)
  │ 
  │     ;; Extra space for didactic purposes
  │ 
  │     (fg-heading-1 rainbow-1)
  │     (fg-heading-2 rainbow-2)
  │ 
  │     (bg-heading-1 bg-blue-nuanced)
  │     (bg-heading-2 bg-yellow-nuanced)
  │ 
  │     (overline-heading-1 blue-faint)
  │     (overline-heading-2 yellow-faint)
  │ 
  │     ))
  └────

  Always remember to reload the theme for changes to take effect.
