0.3.0

Breaking changes

• Package now requires Emacs 29.1 or later (previously 26.1).
• :layout values left and compact are deprecated; use :layout top
  with :compacted nil or :compacted t instead. Legacy values are
  still accepted and auto-migrated.

Layout and compaction

• :layout and :compacted are now independent block parameters.
  :layout accepts top or centered; :compacted is a boolean
  that controls gap-filling behavior regardless of layout.
• New commands org-mindmap-switch-layout and
  org-mindmap-switch-compaction toggle these settings independently.

Node text wrapping

• :max-width block parameter controls soft word-wrap of node text.
  Accepts an integer column limit, nil (no wrapping), or auto
  (calculate from window width and tree depth).
• :wrap-leaves controls leaf-node wrapping: nil disables, t
  enables, and a float value acts as a multiplier on max-width for
  leaves.
• org-mindmap-min-width custom variable prevents orphaned words by
  joining short lines with the previous line.
• Default max-width is auto when :max-width is not specified.
• Wrapping is purely visual: the logical node text stays unchanged
  (newlines replace spaces when rendering, spaces replace newlines
  when parsing).

Cursor position preservation

• The parser now tracks the cursor offset within node text across
  parse-render cycles. After structural edits the point is restored
  to the same logical position within the edited node.

Subtree coloring

• Subtrees can be painted in different colors for visual
  differentiation.
• org-mindmap-color-palette-fn controls the palette source: from
  font-lock faces, rainbow-delimiters, or a fixed RGB triplet.
• org-mindmap-color-assign-fn controls color assignment: by node
  position in tree or by text hash.
• org-mindmap-paint-tinge-fg and org-mindmap-paint-tinge-bg
  control the blend ratio of colors with the underlying faces.
• :paint-depth block parameter and
  org-mindmap-default-paint-depth control the tree depth at which
  painting starts.

CJK support

• Chinese, Japanese, and Korean characters are now supported.

Connector customization

• org-mindmap-parser-connectors allows customizing the Unicode
  box-drawing character set used for tree rendering. Multiple
  connector packs can be defined; the first pack is used for
  rendering, all packs are recognized during parsing.

Minor mode

• org-mindmap-mode is now a proper minor mode with its own keymap.
  It binds RET, TAB, M-RET, M-<up>, M-<down>,
  M-<left>, and M-<right> for structural editing within mindmap
  blocks.
