#enrichedwheatproduct

We are maturing tug from a Hello World demo into a more complete system to handle yet more complex developer scenarios.

Changes include:

• Opinionated in favor of specifically amd64-compatible hosts when cross-compiling applications.
• More complete buildx command line flag support
• Disable the linux/mips64 (Big Endian) platform by default. This was missing from various and sundry base images on Docker Hub and had been forcing architecture exclusion lists to be unnecessarily unwieldy.
• More debug logging information about low level docker commands involved in tug builds.
• Future proof support for appending additional, undocumented platforms beyond what buildx inspect indicates.
• Batching, especially for hosts with limited resources.

#works

Release archive includes pre-compiled binaries of tug for a wide variety of developer platforms.
