Beginning with this release, only one binary is published, which includes a dependency on ArrayFire for hardware acceleration. Installing TinyChain without hardware acceleration is still supported using `cargo install tinychain`. A new Dockerfile and install script are provided to support automatic installation of all dependencies.

Changelog:
* Filesystem cache now supports truly concurrent eviction with freqfs: https://github.com/haydnv/freqfs/
* Improved transaction lock performance under load
* Improved block lock performance under load
* Tensor bugfixes
* Improved anonymous class support in the Python client
