Release Notes

monopipe 1.0.0 - 28 Oct 2026

First stable release, promoting 1.0.0 Beta 1 unchanged apart from the toolchain.

  • Built with Go 1.27.3 to pick up the fix for the eMudura TLS issue.
  • go.mod now requires Go 1.27.3 (was 1.25.0), so builds from source can't fall back to an older toolchain without the fix. This also brings in Go 1.27's default runtime (GODEBUG) settings.

monopipe 1.0.0 Beta 1 - 21 Jun 2026

  • Initial release
  • Capture mode: run a command like time, multiplexing its stdout, stderr, and exit code into a single ordered JSONL stream on stdout
  • Split mode (-s): read that JSONL stream on stdin and demultiplex it back into real stdout and stderr, mirroring the recorded return code so monopipe stays transparent in a pipeline
  • One JSONL record per output line, or per 512 bytes when a line is longer, emitted through a single serialised writer — readable line-by-line, well-formed, streamed in real time, bounded memory for large output
  • Output kept as human-readable text when valid UTF-8, with byte-exact base64 fallback (stdout_b64 / stderr_b64) for arbitrary binary output
  • Incomplete trailing UTF-8 sequences are carried across read boundaries, so multi-byte runes never spuriously trigger the base64 fallback
  • Child stdin is forwarded in capture mode, so interactive programs and filters work
  • Lenient split parsing: ignores unrecognised keys, applies multiple recognised keys per line, and skips lines carrying none
  • Signal-terminated children report a POSIX 128+signal exit code (Unix)
  • Written in Go with zero external dependencies — stdlib only
  • Distributed as platform-specific Python wheels via bin2whl (pip install monopipe)
  • Cross-compiled for macOS (arm64/amd64), Linux (arm64/amd64), Windows (arm64/amd64)
  • Statically linked single binary — no Python runtime needed at execution time
