Kth

You can install Knuth node version v0.25.0 [using these instructions](https://kth.cash/#download).

This release includes the following features and fixes:

- Knuth's build system ([kthbuild](https://github.com/k-nuth/kthbuild)) has been completely rewritten.
For x86-64 systems (AMD, Intel, etc.) kthbuild now supports all five industry-defined [microarchitecture levels](https://en.wikipedia.org/wiki/X86-64#Microarchitecture_levels): x86-64-v0, x86-64-v1, x86-64-v2, x86-64-v3, and x86-64-v4.
This version of node has been compiled using kthbuild v1.0.37.
We have chosen to distribute binaries compiled using the x86-64-v3 microarchitecture level.
However, if your platform does not support the x86-64-v3 microarchitecture level, kthbuild will automatically compile from source using your platform's specifications.
And if your platform is better than x86-64-v3, you can take advantage of your hardware by compiling node with `-o march_strategy=optimize`.
- Uses C++ API v0.25.0
- Support for Visual Studio (MSVC) has been temporarily discontinued.
- Some external dependencies were updated.

- [CHIP-2021-03: Bigger Script Integers](https://gitlab.com/GeneralProtocols/research/chips/-/blob/master/CHIP-2021-02-Bigger-Script-Integers.md) increased precision for arithmetic operations.
- [CHIP-2021-02: Native Introspection Opcodes](https://gitlab.com/GeneralProtocols/research/chips/-/blob/master/CHIP-2021-02-Add-Native-Introspection-Opcodes.md) enabling smart contracts to inspect the current transaction.

You can install Knuth node version v0.20.0 [using these instructions](https://kth.cash/#download).

This release includes the following features and fixes:

- The version number of the executable was unified with the user-agent displayed by the node. For this reason the version interval (0.9.1, 0.20.0) of the node executable will be skipped.
The user-agent presented by the node comes from the core C++ library, so all other components that depend on it (executable, C-API, C-API, Javascript-API and TypeScript-API) will show the same user-agent.
- Some bug fixes.
