 ## [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.
