New features

• Removed warning about changed node.
• Added scroll-outline-left/right commands.
• Leo outputs decorators correctly, assuming the decorator does not conflict with a Leo directive.
• Wrote script to convert g.es to g.et where appropriate. The first step in translating all Leo messages.
• Leo highlights (flashes) matching brackets when typing typing (, ), [, ], { or }.
• Fixed long-standing problem reporting indentation errors.
• Fixed long-standing bug in Remove Sentinels command.
• Fixed long-standing bugs in import commands.
• The scroll-up/down commands now scroll the outline if focus is in outline pane. However, his can be done better using per-pane bindings as in the default leoSettings.leo.
• Incremental searches are (properly) confined to a single body text.
• Backspace now handled properly in incremental searches.
• The add-editor command adds a new editor in the body pane. The delete-editor command deletes the presently selected editor, and the cycle-editor-focus command cycles focus between editors in the body text.
• The standard 1, 2, etc. replacements can now be performed in regular expression searches.
• The standard escapes n and t are now valid in plain searches.
• The shortcut for the replace-string command now changes from the find command to the replace command.

New and improved plugins

• The slideshow plugin
• The mod_scripting plugin now creates a press-x-button command for every button ‘x’. You can specify settings for such commands using @shortcuts nodes.
• The shortcut_button plugin plugin creates a ‘Shortcut’ button in the icon area. Pressing the Shortcut button creates another button which when pressed will select the presently selected node at the time the button was created.
• Added Debug button to scripting plugin.
