 ## [Unreleased] - ReleaseDate
 
-## [2.6.0] - 2025-06-30
-
-### Added
-
-- Added support for Minecraft 1.21.5 to 1.21.7
-
-  Added new block types and handling for changed sign text storage format.
-
-## [2.5.0] - 2025-03-16
-
-### Added
-
-- Added experimental watch mode
-
-  Passing `--watch` will cause MinedMap to run continuously instead of exiting
-  after map generation, regenerating tiles whenever they change.
-
-  `--watch-delay` can be used to configure the delay between detecting a change
-  and runing the map generation, also limiting how often the regeneration
-  happens. This defaults to `30s`; significantly smaller values probably don't
-  make sense because Minecraft writes out changes in batches anyways.
-
-  Finally, `--jobs-initial` can be used to configure the number of parallel
-  generation threads for the initial cycle separately from the value used for
-  subsequent cycles after a change is detected (`-j`/`--jobs`). Subsequent
-  cycles usually need to regenerate only a small number of tiles, so setting
-  `--jobs` to a smaller value than `--jobs-initial` may be advantageous.
-
-- Added jemalloc support to fix performace on musl targets
-
-  The global allocator can be switched to jemalloc by enabling the `jemalloc`
-  cargo feature now. This is not the default because it is not always faster
-  than the default system allocator; in particular, the glibc allocator has
-  slightly better performance in multithreaded mode. In addition, jemalloc
-  uses a bit more memory.
-
-  In addition, the `jemalloc-auto` feature has been introduced, which is enabled
-  by default and sets the global allocator to jemalloc on platforms where it is
-  clearly advantageous. For now, this is only done on musl-based targets, as
-  musl's default allocator is very slow in multithreaded operation (which was
-  making higher thread counts like `-j8` basically useless due to 7-8x
-  slowdowns). With the new default, performance on musl is basically identical
-  to glibc.
-
-  Note that some platforms like `msvc` are unsupported by jemalloc, and trying
-  to enable the `jemalloc` feature on these platforms may break the MinedMap
-  build or cause issues at runtime.
-- Docker images can be downloaded from the GitHub Container registry
-
-  Two images are provided, one for the tile renderer and one with the viewer
-  and a web server. A `docker-compose.yml` example can be found in the
-  repository as a starting point.
-
-### Changed
-
-- Unknown biome types (from not yet supported or modded versions of Minecraft)
-  will now use plains biome colors as a fallback instead of resulting in water,
-  grass and foliage blocks to be rendered as transparent pixels
-- Switched from zlib-ng to zlib-rs
-
-  This should have no noticable effect on the usage of MinedMap, but avoids
-  an external build dependency on CMake.
-- Small (1-block) seagrass is now visible on the map
-
-  1-block seagrass in 1-block deep water would previously result in the ground
-  to be shown instead of water, as MinedMap currently doesn't handle the
-  "waterlogged" block status. As 1-block seagrass is relatively big compared to
-  other "small" plants, just considering it opaque seems like a good enough
-  solution that avoids having to implement advanced block status flags.
-- Use Bincode 2 for storage of intermediate data
-
-  The update from Bincode 1 to 2 slightly reduces the size of the `processed`
-  directory used for intermediate data. At least Rust 1.85 is now required to
-  build MinedMap.
-
-## [2.4.0] - 2025-01-11
-
-### Added
-
-- Added support for rendering tiles in WebP format using the `--image-format` option
-
-## [2.3.1] - 2025-01-06
-
-### Fixed
-
-- Fix text colors for signs modified using dye
-- Fix text colors specified using `#rrggbb` CSS syntax in JSON text
-
-Only named colors specified via JSON text were working as intended.
-
-The mapping of color names to values is now handled by the generator. Both the generator and the
-viewer must be updated for sign text colors to work.
-
-## [2.3.0] - 2025-01-02
-
-### Added
-
-- Added support for Minecraft 1.21.4 block types
-- Added support for Minecraft 1.21.4 Pale Garden biome
-- viewer: added images for pale oak signs
-
-## [2.2.0] - 2024-06-23
-
-### Added
-
-- Added support for Minecraft 1.21 block types
-
-## [2.1.1] - 2024-06-14
-
-### Fixed
-
-- Fix crash due to incorrect counting in info message
-
-  The calculation of the number of skipped regions could underflow when more invalid than valid
-  regions were encountered.
-- Ignore empty region files instead of treating them as invalid
-
-  Minecraft generates empty region files in some cases. Just ignore them instead of printing an
-  error message every time.

-    After regenerating, check if only new biomes were added. If entries

 After the update, the new version should be tested with old savegames (both
 before and after migration by the new version) as well as newly generated
 worlds. Use creative mode to add the new block types to your test world.
