0.70.0

Added

• Undo tree visualization — branching undo history with g+/g- chronological navigation across all branches (buffer content changes via ChangeSet dispatch), :earlier N/Ns/Nm/Nh/Nd/Nf and :later time/count/save-point navigation, :undolist modal, sidebar view (:UndoTreeToggle/Show/Hide) with DOM tree rendering, click-to-navigate, keyboard nav (j/k/Enter/q), collapse/expand branches, relative timestamps, summary diff preview, vim.fn.undotree() Lua API (Neovim-compatible dict), optional persistence (set undofile), per-file undo tree map, Obsidian commands for sidebar management. Inspired by undotree.
  • Plugin: src/vim/undo-tree.ts (shadow tree data structure), src/vim/undo-tree-view.ts (sidebar view), src/main.ts (CM6 integration, g+/g- actions, persistence hooks), src/workspace/commands.ts (ex commands), src/lua/fn.ts (vim.fn.undotree())

Changed

• minAppVersion bumped from 1.6.6 to 1.7.2 — required for Workspace.revealLeaf() used by undo tree.

Fixed

• g;/g,/g-/g+ keymaps not working after reloadFeatures() — the changelist and undo tree mapCommand registrations were only in onload() but not in reloadFeatures(). Since reloadFeatures() calls unregisterAll() (which wipes all custom keymaps) and then re-registers features, these keymaps were silently wiped on any settings change, vimrc load, or Lua config load. Fixed by adding the registrations to reloadFeatures().
  • Plugin: src/main.ts (added changelist + undo tree mapCommand calls to reloadFeatures())

Tests

• 66 unit tests in test/unit/undo-tree.test.ts: data structure (branching, navigation, pruning, time lookup, Neovim dict), serialize/deserialize round-trip, findBySaveCount, computePath, navigating flag, ChangeSet storage
• 8 e2e tests in test/specs/undo-tree.e2e.ts: CM6 integration, g+/g-, :earlier/:later, :undolist
• 4 e2e tests in test/specs/undo-tree-view.e2e.ts: sidebar open/close, node rendering, current marker
• 5 e2e tests in test/specs/undo-tree-navigation.e2e.ts: buffer content changes via :earlier/:later, g+/g- safety
