[0.1.9] - 2022-06-13

Changed

Updated from actix-web 1 to 4, in preparation for more asynchronous IO.

[0.1.8] - 2022-06-07

Changed

Updates to dependencies for bug fixes.

[0.1.7] - 2020-10-22

Fixed

Fixed a soundness error in a dependency that caused a panic on Rust 1.48 and greater (see this issue).
Reduced allocation frequency and size for encoded tiles.

[0.1.6] - 2020-07-18

Fixed

Fixed a panic when a block's dataset-level bounds overlapped a tile request but the block's actual bounds did not.

[0.1.5] - 2020-07-13

Added

An optional LRU memory cache for tiles can be enabled with the --tile-cache option. The size of the cache (in tiles) globally can be configured with the --tile-cache-size option. HTTP server caching should be preferred for production deployments, but this option is useful for temporary cases.

Fixed

Fixes from dependencies include a bug that caused n5 to corrupt the version attribute when opening datasets and extremely rare cases where PNG tiles would be corrupted during compression.

[0.1.4] - 2019-11-15

Added

An optional LRU memory cache for blocks can be enabled with the --ds-block-cache option. The size of the cache (in blocks) per-dataset can be configured with the --ds-block-cache-size option.
Scalar value bytes can be packed into channels by adding a pack query parameter to request URLs. For example: ?pack=rgba.
FLOAT32 and FLOAT64 datasets are now supported via channel packing.
The maximum size (in bytes) that will be preallocated for a tile before decoding can be configured with --max-tile-prealloc.
Logging is now enabled via env_logger.

Changed

Actix-web and many other dependencies underwent major update that include security issues.
Cumulative optimizations can improve request response times by 40%.

Fixed

A bug that could cause a panic on some platforms and environments has been fixed.
