Release Notes for Agar 1.4.1
----------------------------

Here are some of the most notable changes since Agar 1.4.0, in no
particular order. A wikified version of this list is available at:
http://wiki.libagar.org/wiki/Agar-1.4.1.

- Port to Xbox (thanks Michael J. Wood!).
- Widget code can now use the AG_Redraw() and AG_RedrawOn*() interfaces to
  trigger rendering. The generic event loop uses this information to avoid
  unnecessary video updates -- custom event loops should be modified to
  test for the window "dirty" flag to take advantage of this feature.
- Fixed compilation with --disable-legacy option.
- Implemented AG_SurfaceFromPNG() and AG_SurfaceFromJPEG().
- Fixed crash bug in AG_SurfaceFromSDL(); thanks trapdoor!
- Added AG_SetJPEGQuality(), to set quality used by AG_SurfaceExportJPEG().
- Merge --enable-{class,event}debug into --enable-objdebug; remove lockdebug.
- Upgrade build system to BSDBuild 2.8. Note that stale ./agar-config/ and
  ./agar-foo-config/ directories may break the build and should be removed
  before ./configure is executed.
- Fix deadlock condition with the AG_Timeout interface when timers are
  scheduled in reverse order; thanks to Jakob Reschke for the fix!
- Fixed UTF8 conversion bug with 3-byte sequences; thanks Jerry Huang!
- Fixed coordinates offset for popup menus under single-window drivers.
- Numerous improvements to the API reference. Added AG_DriverGLX(3),
  AG_DriverWGL(3), AG_DriverSDLFB(3), AG_DriverSDLGL(3), AG_DriverMw(3)
  and AG_DriverSw(3), AG_InitGraphics(3) manual pages.
- Fixed crash bug with AG_TEXTBOX_STATIC and AG_EDITABLE_STATIC.
- Added "STRUCTURE DATA" section to AG_Window(3).
- Added missing SDL_LockSurface() calls in sdlfb/sdlgl drivers.
- AG_InitGraphics() can now accept driver initialization arguments.
- Avoid use of gettimeofday() on cygwin platform.
- MATH: Fix type conversion warnings.
- Implemented AG_DirDlg(3) directory selection widget.
- Implemented AG_Anim(3) interface.
- WGL: Terminate application by exiting the event loop instead of
  using exit().
- In AG_Scrollbar(3), implement AG_SCROLLBAR_AUTOHIDE option.
- Fix compilation issues under MinGW / MSYS (thanks Joergen!)
- WGL: Post a "window-gainfocus" event when a window is focused for
  the first time on creation.

Agar-1.4.0 released

Agar Announcements — 2010-04-16T15:52:52

I am pleased to announce the immediate release of Agar-1.4.0. The
source code and some precompiled packages are now available for
download at:

http://libagar.org/download.html

Release Notes for Agar 1.4.0 ("Landscapes of Frozen Methane")
-------------------------------------------------------------

Here are some of the most notable changes since Agar 1.3.4, in no
particular order. A wikified version of this list is available at:
http://wiki.libagar.org/wiki/Agar-1.4.0.

This release preserves backward compatibility with Agar 1.3.4, but it is
recommended to compile Agar with the `--disable-legacy' configure option,
ensuring that existing applications are not using deprecated API calls.

- Added support for multiple native windows; rework of the low-level graphics
  and input device interfaces. As of this release, the available drivers are:
  - "glx" (GL rendering via X Window System; multiple windows)
  - "wgl" (GL rendering under Windows; multiple windows)
  - "sdlfb" (framebuffer rendering via SDL; internal WM)
  - "sdlgl" (GL rendering via SDL; internal WM)
  New drivers can also be implemented as part of an application, the driver
  API is documented in AG_Driver(3).
- Applications should now use AG_InitGraphics() to initialize the graphical
  interface. Backward compatibility is preserved, but AG_InitVideo() will
  only select among single-window graphics drivers.
- Agar can now be built without the SDL library, where the SDL graphics
  driver is not needed.
- Many improvements to the AG_Surface(3) interface.
- Implement generic AG_Keyboard and AG_Mouse interfaces; allow for multiple
  input devices.
- Implement widget "actions" as a generic method of handling mouse and
  keyboard actions per user preferences (see AG_Widget(3)/ACTIONS).
- Agar windows are now attached and detached using AG_ObjectAttach() and
  AG_ObjectDetach() against a parent AG_Driver(3); the AG_ViewDetach()
  function is now deprecated.
- Added AG_Tbl(3), AG_Tree(3) interfaces to ag_core.
- Fix handling of dynamically-allocated strings in AG_CopyVariable().
- Implement AG_TlistUniq(), AG_TlistAddHead().
- Important optimizations to AG_LookupClass().
- Consistently provide plain string variants for every function accepting
  format string arguments. This allows for more efficient code, and avoids
  complications with language bindings.
- As the "window-*" prefixes in events such as "window-mousemotion" is no
  longer relevant, mark them deprecated in favor of "mouse-*" and "key-*".
- The integer typedefs Uint8, Sint8, Uint16, Sint16, etc. are no longer
  made public unless _USE_AGAR_TYPES is explicitely defined.

Agar-1.3.4 released

Release Notes for Agar 1.3.4 (Pandemonic Incantation)
-----------------------------------------------------

Here are some of the most notable changes since Agar 1.3.3, in no
particular order. A wikified version of this list is available at:
http://wiki.libagar.org/wiki/Agar-1.3.4.

- Continued improvements to the API reference.
- Overall improved handling of out-of-memory conditions.
- Implement simpler, unified AG_Variable(3) interface at the AG_Object(3)
  level in ag_core. This renders the AG_Widget(3)-level "AG_WidgetBinding"
  and the "AG_Prop" interfaces obsolete, as well as the AG_Event(3) argument
  lists, which all used different structures and interfaces. Backwards
  compatibility is preserved.
- GUI: Implemented word-wrapping in AG_Editable(3) and AG_Textbox(3). Thanks
  to CoKinetic Systems (http://www.cokinetic.com/) for sponsoring this feature!
- Perl XS bindings improved to the level that they are now useful, thanks to
  Mat Sutcliffe!
- Continued improvements to the Ada bindings; added ada-demos/
  (thanks rothwell!)
- Remove unnecessary --disable-utf8 switch, always use Unicode.
- Removed DEV_GuiDebugger() from ag_dev library. Reimplemented a more useful
  debugging tool, AG_GuiDebugger(), in ag_gui itself.
- Fixed font engine initialization/clean-up issue which prevented Agar from
  being destroyed and re-initialized later (thanks naiina!)
- CORE: Eliminate unnecessary list traversals when scheduling timeouts.
  AG_ScheduleTimeout() is now preferred over AG_AddTimeout() and
  ReplaceTimeout().
- CORE: Added AG_LookupDSO() to AG_DSO(3) interface.
- CORE: Added public AG_ObjectReadHeader() routine, for checking object file
  metadata prior to loading.
- CORE: Added AG_Time(3) interface.
- CORE: Implemented support for database-bound objects with AG_Db(3) and
  AG_DbObject(3).
- CORE: Added AG_List(3) interface to complement AG_Variable(3).
- CORE: Agar datafiles now support debugging information and optional runtime
  type-safety. Added agar-disasm utility for dumping contents of Agar
  object datafiles with debug information (see AG_SetSourceDebug()).
- CORE: Implemented "AutoCore" (dynamically-grown memory) data source into
  AG_DataSource(3).
- CORE: Much improved error handling in AG_DataSource(3). Added
  AG_DataSourceSetErrorFn(), and error-return variants for all standard
  AG_ReadFoo() routines.
- CORE: Added simpler AG_ConfigLoad() and AG_ConfigSave().
- Merged NS/NC library ("ag_net") into ag_core.
- Updated build system components with latest BSDBuild
  (http://bsdbuild.hypertriton.com/).
- GUI: Added widget: AG_FontSelector(3).
- GUI: Added widget: AG_Scrollview(3).
- GUI: Added widget: AG_Treetbl(3) (based on previous "AG_Tableview").
- GUI: Added advisory AG_Widget(3) flag AG_WIDGET_TABLE_EMBEDDABLE.
- GUI: Added AG_TextFontPts(), AG_TextFontPct(), AG_TextFontLookup(),
  AG_TextValign(), AG_ButtonValign().
- Fixes to AG_Label(3) clipping when partially occluded.
- GUI: Added AG_TextInfo() (similar to AG_TextWarning(), with disable key).
- GUI: Cosmetic fixes in AG_Menu(3).
- GUI: Implemented AG_InitGUI(), AG_QuitGUI().
- GUI: Implemented AG_VIDEO_OVERLAY option to simplify rendering of Agar GUI
  elements over an existing OpenGL scene when a custom event loop is needed.
- GUI: Avoid the slow recursive searches needed by functions such as
  AG_WindowUpdate() by storing a "window" pointer in the Widget structure.
- GUI: Clean up focus-related code. Allow AG_WidgetFocus() to fail. Add
  separate AG_WidgetIsFocusedInWindow() routine in addition to
  AG_WidgetIsFocused().
- GUI: Fix a potential problem on platforms where the GL context is lost
  following a window resize.
- GUI: Allow widgets to request geometry updates asynchronously with
  AG_WidgetUpdate(). This avoids redundant, expensive searches. Use of
  AG_WindowUpdate() within widget implementations is now strongly deprecated.
- GUI: Fix incorrect parsing of "Npx" size specifications in
  AG_WidgetParseSizeSpec().
- GUI: Implement AG_WidgetSurface(), for rendering widgets to an AG_Surface(3).
- GUI: Fix improper initialization and cleanup of embedded widget cells,
  improve handling of out-of-memory conditions.
- GUI: Fix scrolling behavior of AG_Console(3), add AG_ConsoleClear(),
  AG_ConsoleMsgIcon() and AG_ConsoleMsgPtr().
- Removed remaining SDL dependencies in GUI rendering code and ag_core.
- GUI: Use stippled polygons in GL mode for "disabled" widget controls. Add
  AG_DrawArrowLeft(), AG_DrawArrowRight().
- GUI: Embed AG_Label(3) in AG_Button(3) instead of rendering text. Added
  constructors AG_ButtonNewUint{8,16,32}().
- GUI: Embed AG_Label(3) in AG_Checkbox(3) instead of rendering text.
- GUI: Some small optimizations to text rendering system.
- GUI: Cosmetic fixes to decorative window frames and rendering of "resize"
  controls.

  AG_FileDlg(3) on platforms where glob(3) is available.
- GUI: AG_FileDlg(3) now displays OS-specific directory shortcuts. Display
  drive letters on win32.
- GUI: AG_Slider(3): added AG_SliderNewFooR constructor variants, added
  AG_SliderSetControlSize().
- GUI: Implemented AG_PixmapFromTexture() constructor and
  AG_PixmapFooCurrentSurface in the AG_Pixmap(3) widget.
- GUI: Added support for caption text in AG_Box(3).
- GUI: Added AG_HSVPAL_NOALPHA and AG_HSVPAL_NOPREVIEW options to AG_HSVPal(3).
- GUI: Added AG_WIDGET_NOSPACING flag to request that parent container widgets
  do not apply spacing around the widget.
- GUI: The polling rate of AG_Tlist(3) is now controllable with
  AG_TlistSetRefresh() and AG_TlistRefresh(). Added AG_TlistScrollToStart()
  and AG_TlistScrollToEnd() routines.
- GUI: Added AG_TableSetColHeight(), AG_TableSetRowHeight(),
  AG_TableSetColMin(), AG_TableSetSelectionMode() and
  AG_TableSetSelectionColor().
- GUI: Added AG_RadioNewUint(). Fixed clipping in AG_Radio(3).
- GUI: Added AG_ProgressBarNewInt().
- GUI: Implicitely glPushAttrib(GL_TRANSFORM_BIT) in AG_GLView(3).
- GUI: Rework of the "modal window" system to keep modal windows in a stack.
  This fixes a bug that would occur with cascading modal windows (e.g., a
  modal window created from an event handler of another modal window).
- GUI: Rework of the logic responsible for cycling focus between widgets with
  the "tab" key. The new version is more efficient and fixes focusing bugs
  that would occur when using certain container configurations.
- GUI: Added public AG_WindowFocusAtPos() (was previously an internal).
- GUI: Implemented AG_WindowSetGeometryRect(), AG_WindowSetMinSizePct(),
  AG_WindowSetSideBorders(), AG_WindowSetBottomBorder().
- GUI: Fixed many issues with AG_Pane(3). AG_PaneMoveDivider() now
  works pre-WindowShow(), added AG_PaneMoveDividerPct(). Fixed incorrect
  documentation of the AG_PANE_DIV flag (actually divides area by two).
  Added AG_PANE_UNMOVABLE option. The divider is now resizable to 0 pixels.
- VG: Fixed rendering of VG_Polygon(3).
- VG: Implemented general-purpose "select" tool (adapted from Edacious).
- VG: Added VG_ViewSetScalePreset(), VG_ClearEditAreas(), VG_EditNode(),
  VG_DrawSurface(), VG_ToolCommandExec() to VG_View(3) widget. Improvements
  to "text" tool, such as font selection.
- VG: Library is now usable without Agar-GUI.
- VG: Added VG_Merge().
- VG: Added variable substitution and removed complex parser from "polled"
- VG_Text element, thanks to the new AG_Variable(3) system.
