flextabs v0.3.0

New

• Built-in icon set, IconManager.get_builtin_icon(), render(), register_icon() and builtin_names()
• Themes: theme= argument, set_theme(), Palette, LIGHT, DARK, apply_app_theme() and apply_fonts()
• close_button_style="button" with close and lock glyphs on tabs
• get_tab_index(), enable_dpi_awareness(), the flextabs-demo command and type information (py.typed)

Changed (check these when upgrading)

• Python 3.15 or newer is required
• The default look is now the flat "auto" theme; pass theme=None for the previous plain ttk look
• Tabs without an icon no longer get a fallback icon by default (use_fallback_icons and use_notebook_fallback_icons are now False); fallback icons map to built-in icon names, and IconManager.get_fallback_text() returns an icon name
• Icons are classified as image files by path separator or image extension rather than by length
• Tabs that are not closable no longer get a • prefix or grey styling
• Sidebar: default width is 180 (was 150) and the title is shown at the top
• Themed opener buttons use the ttk selected state for the selected tab and alternate for open tabs; the plain look still marks open tabs with selected
• get_current_tab() reads the notebook's live selection
• Destroying the manager runs every open tab's cleanup() and does not call the on_tab_* callbacks
• Errors are logged with logging instead of printed
• ToastNotification.COLORS only lists the status accent colours; toasts take their colours from the palette
• TooltipWidget uses TkDefaultFont and wraps at 280 pixels by default

Fixed

• Shortcuts no longer replace your app's bindings or each other, and removed tabs lose theirs
• Selecting tabs after they were reordered, image icons with more than one Tk root, menus with dict icons, the menu opener leaving menus behind, callback errors failing open_tab()/close_tab(), and several smaller issues

Install: pip install flextabs==0.3.0 (requires Python 3.15+)
