Version 2.4.1

Bug fixes

• Fixed broken "open world" dialog #75
• Fixed an exception while rendering old chunks introduced by the negative y coordinates in 1.18

Version 2.4.0

Changes

• Added support for 1.18 worlds
• Added a force-reload action that bypasses the cache. Shortcut Ctrl+Shift+R
• Newer fancier heightmap and biome view
• Changed the default settings for some of the pins (maps and treasures are now hidden by default)
• Added name and color information to banner pins (not pretty yet, but better than nothing)

Bug fixes

• Fixed banner pin positions (#40, #70, thanks @Reispfannenfresser)
• Fixed that changing the world would not cancel the old render tasks (a114616)

Version 2.3.0

Changes

• Minecraft 1.17 support
• GUI rendering engine improvements
  • The way downscaled images are handled got changed. The resulting code is a lot simpler,
    which results in less bugs and memory consumption.
  • The difference is especially noticable in worlds with empty region files/chunks. This
    occurs when using the /locate command, or when interacting with cartographers in game.
• Added pin for Lodestones

Bug fixes

• Some random NullPointerExceptions
• Java >=16 support

Version 2.2.1

Changes

• Minor changes to the resource generation—CI is now slightly faster and should fail less often
• Updated screenshots in README

Bug fixes

• Minor improvements in the open dialog
• Fixed pins for multiple maps on the exact same place

Version 2.2.0

Changes

• New "open" dialog
• Dragging the map is now done with the left mouse button, like in any other reasonable map viewer.
• Show a timestamp of when the world was last rendered
• The GUI now has command line options
  • Optionally specify a path as command line argument, which will be loaded on startup
    • This allows associating files and folders with BlockMap: Right click a Minecraft save folder -> Open with -> BlockMap \o/
  • -v or --verbose to enable debug messages
• Custom URI scheme handler
  • If you have an URL pointing at a BlockMap server location (usually some index.json, prefix it with blockmap:
  • The browser (or any other application with URL scheme handling support) will now prompt and ask to open said world in BlockMap
  • More features, like linking a specific location may be added in the future
• Switching into the Nether and back adapts the view to the fact that the Nether is smaller than other dimensions (#51)
• Better caching of several things
  • Recently opened worlds are now saved and displayed first when loading
  • Player skins and UUID won't be fetched every time from Mojang servers
• Server command line changes (render-many)
  • Removed most command line options and moved them into the configuration file itself
  • Added fine-grained control about which pins to include when rendering, and which not (for both file size and privacy/cheating reasons)

Bug fixes

• BlockMap accidentially opened the region files with RW permission, even if it does not modify them.
• Player pins are no longer blurry (#48, #49)
• Maps from 1.16 worlds load properly now
• URLs with missing trailing slash (as https://blockmap.exmaple.com) don't throw an exception anymore (#54)

Version 2.1.0

Changes

• Minecraft 1.16 support
  • Renderer supports the new save format
  • Added all new nether blocks to the color maps
  • Added biome colors for the new Nether biomes
  • Added new village pins: bee_nest, nether_portal
  • Added new Nether pins: bastion_remnant, nether_fossil
• Reordered a few of the pins (among other tweaks)

Bug fixes

• Fixed village pins showing up in the wrong dimension
• Fixed a few minor errors in the color maps

Version 2.0.0

breaking news for breaking changes! Long overdue, a rewrite/overhaul of quite a few components. No Minecraft 1.16 support yet.

Changes

• GUI redesign:
  • Autocomplete!
  • Better support for viewing worlds on servers.
  • Rewrite of the map rendering engine
    • Much cleaner code, probably removed a lot of bugs
    • Removed caching (may increase memory usage in large worlds)
  • Removed saving support. Use the CLI instead.
• breaking World representation has been changed. Previously, every folder containing region files would count as world. Now, a world always is a folder containing a level.dat together with a dimension (defaulting to the overworld).
  • For the CLI, a few paths will have to be changed. --dimension is now always used, but defaults to OVERWORLD.
  • For the GUI, nothing much will change except you cannot open a single region folder anymore (which probably nobody did anyways)
• New server mode using render-many:
  • It is not declared stable yet, to allow breaking changes even on minor version bumps.
  • Declare a configuration file with all your worlds and how you want to render them. An example configuration can be found here.
  • Call blockmap render-many and pass the configuration file as argument. You can add dynamic server information like online plyers etc. via more command line options.
  • An output directory will be created with all the rendered files. You can view them in BlockMap.
  • Host that folder using the web server of your choice (e.g. miniserve). Clients will now be able to view your worlds across the Internet.
  • Call this on a scheduled basis. Subsequent runs will update the folder without re-rendering everything.
• Other CLI changes:
  • breaking The --lazy option has been removed and is no enabled by default. Use --force to disable it manually.
  • Proper exit code handling. When using BlockMap in scripts, you'll know when it fails.
• Java 13 support

Bug fixes

• Color map selection in the GUI has gone wrong a few times
• Some bounds checks when rendering part of the world are notoriously wrong
