Biome Painter 1.1 - 5/12/2013

• Fix checking for block color, biome color, and program updates no longer working.
• Include default block colors though Minecraft 1.5 and snapshot 13w19a.
• Chunk loading and terrain map rendering are now multi-threaded. On computers with multiple processor cores this can significantly speed things up. On systems with a single-core processor there should be no noticeable difference.
• Updated label for biome generation from Minecraft 1.4.1 to 1.4.2 since they're the same.
  • Added option to fill/replace biomes with those from Minecraft 1.5.2, though it should be identical to 1.4 too.

Biome Painter 1.0 - 12/25/2012

• Check for updates window now has separate options for block colors, biome definitions, and the program itself. The first two can download updates on demand. The last will open a web page with links to download the updated version.
• Block colors are now split between two files: Blocks.default.txt and Blocks.user.txt. The former shouldn't be edited manually. Updated versions of the file can be downloaded from the "Check for updates" option in the Help menu. This checks the Blocks.default.txt file on GitHub.com, which will be updated with new blocks as they're added to the game. Entries in Blocks.user.txt will never be overwritten by Biome Painter and always override values in Blocks.default.txt.
• Biome definitions and colors are now split between two files: Biomes.default.txt and Biomes.user.txt. See the description of the new separate files for block colors, above.
• A save's level.dat can now be "open[ed] with" Biome Painter.
  • After this has been done at least once, worlds opened with Biome Painter from the file system or through the standard open file window from within the program will be automatically added to the program's jump list and list of recent files in the start menu in Windows 7 or later. Other platforms are not affected.
• Undo and redo buttons and menu items are now disabled when there's nothing for them to do. The buttons also have a tooltip when hovering over them describing what they would undo or redo when clicked.
• A world's seed can be changed from the file menu. This affects filling or replacing with biomes from a given version of Minecraft.
  • A different seed can be used temporarily while the world is open in Biome Painter with the option to also save the new seed to level.dat.
• Display world name in program title bar
• Ability to fill or replace with biomes from Minecraft 1.4.6.
  • Separate Minecraft 1.4.6 large biomes option.
  • Minecraft versions now in descending order in drop down lists.
• Checking for updates now faster.
• Reading region files now faster.
• More robust searching for directories containing region files and handling dimensions that have none.

Biome Painter 0.9 - 9/12/2012

• Terrain map layer now supports transparent blocks and biome colors for grass and leaves. These both make rendering the map slower, however. Options to enable or disable these features can be found under the new "Settings" menu. Additionally there's an option to control whether the terrain map should be re-generated after every biome change, though that would be unnecessary without the biome foliage option enabled.
• A list of the ten most recently opened worlds can be found under the File menu.
  • Settings and recent worlds are stored in settings.xml, wherever BiomePainter.exe is located.
• Block colors used in the terrain map are read from a file, Blocks.txt. Each line should be formatted:
  • blockId[:dataValue][,additionalIds];[optional comma-separated biome ids;]6-8 digit hex color code [aa]rrggbb #optional comment
• Errors are logged to text files saved wherever BiomePainter.exe is found. Nothing is transmitted automatically, however these could be useful in reporting any crashes.
• Ability to fill or replace with biomes from Minecraft 1.3.2.
  • Separate Minecraft 1.3.2 large biomes option.
  • Also added biome generation from BETA 1.3_01 per request. Sorry it took so long.
• Program components combined into fewer, larger DLLs.

Biome Painter 0.8 - 4/20/2012

• Batch processing of an entire dimension of an entire world can now be done from the Edit menu after opening a world and selecting biomes from the drop down lists at the bottom of the main window.
  • Biomes to be used are taken from the existing drop down lists at the bottom of the main window.
  • When canceling a job in progress, if a region has begun to be saved it is allowed to finish before everything is stopped in order to prevent corrupting save files.
• Pasting now allows mousing over and clicking on the region to place the copied biomes instead of typing coordinates.
  • To cancel a paste press Escape, or switch which brush type is selected.
• Fixed reloading the current region when none is loaded.

Biome Painter 0.7 - 4/16/2012

• Two new brush types: rectangle select and fill.
  • Fill or clear a rectangular area by clicking and dragging using the left or right mouse button.

• Fixed End region directory not being found.
• Fixed mouse clicks registering on tooltip instead of region image.

Biome Painter 0.6 - 4/11/2012

• Two chunks into the eight regions adjacent to the currently loaded one are now displayed around the edge of the region map. They are read-only and cannot be selected. Their purpose is to help with lining up changes to biomes that straddle region borders.
• Regions from the Nether or End can be loaded by switching dimensions from the file menu after opening a world.
• Biomes that can be edited with this program are now read from a text file, Biomes.txt, sitting in the same directory as Biome Painter. The format for each line is: [biome id (0-255)],[biome display name], [6-digit hexadecimal color code for the overlay map]. The biome id is the important part and what is recorded in your region files. For more information, see: http://www.minecraftwiki.net/wiki/Data_values#Biome_IDs

Biome Painter 0.5 - 4/9/2012

• New option to add to or remove from the current selection based on existing biomes in the region. For instance, the ability to add every area that is currently taiga to the current selection.
• Number keys now toggle layers on and off.
• While zoomed in, use Alt + Mouse Wheel to pan up and down, and Shift + Mouse Wheel to pan left and right. As before, Ctrl + Mouse Wheel adjusts brush size and Mouse Wheel by itself adjusts magnification.
• Mouse cursor is now hidden while drawing or erasing.
• Fixed panning left or up not working when viewing the bottom-right corner of the region.

Biome Painter 0.4 - 4/6/2012

Biome Painter 0.3 - 4/3/2012

May damage existing structures in affected chunks, please see README.txt, the section "Points of Confusion" for more information.
• Save times dramatically improved. Saving all chunks in a region down from 60 seconds to ~7 seconds in my tests.
• Overhead map indicates height by making higher areas lighter in color.
• Brush visible when mousing over region map. Brush size can now be changed with Ctrl + Mouse Wheel.
• More shortcut keys.
  • Use Ctrl + Up, Down, Left, or Right to switch to adjacent regions.
  • Use Ctrl + G to bring up the jump to coordinates dialog.
• Replaced text on most buttons with an icon.

• Fixed crash bug when a chunk was all or mostly air.

Biome Painter 0.2 - 3/30/2012

• Replaced trackbars with scrollbars for panning.
  • Also after mousing over or clicking on the image the arrow keys can be used to pan up, down, left, and right.
• Zoom in and out with the mouse scroll wheel.
  • For example, if you want to zoom into a particular area in the region, hold the cursor over it and scroll up.
• Undo and redo changes to selection and biomes.
  • Undo history is cleared when closing or opening a world.
  • Changes to biomes are removed from the undo history when changing regions within a world, though selection changes are left.
• Copy biomes under the current selection and paste them elsewhere.
  • Currently when pasting you must specify the coordinates to paste to, relative to 0, 0 at the top-left corner of the region. The default is the coordinates of the top-left corner of what was copied. So, copying and immediately pasting won't actually change anything.
• Menu items for selection operations in addition to buttons.
• Shortcut keys for menu items.
• New overlay: chunk boundaries, hidden by default.
• Fixed mouse movements and clicks registering in wrong location when zoomed in.
• Fixed single right clicking with a brush size of 1 not erasing.
• Removed dependencies not available under Mono.
  • Biome Painter should run without problems on platforms other than Windows using Mono (http://www.mono-project.com), though I have no way to test myself.
