ds4go CHANGELOG

NOTE: This currently needs a patched ds4 to make a shared library and route logging and aborts; we also embed the .metal files. See https://github.com/NimbleMarkets/ds4/tree/nm-shared

v0.5.1 (2026-06-10)

  • Add ds4go install catalog command
  • Add AMD ROCm support
  • Add ds4 SSD streaming support
  • Add session cancellation with session.SetCancel
  • Tool loops now replay assistant reasoning across turns (preserving KV-cache reuse) and recover tool calls the model starts inside an unclosed <think> block.

v0.5.0 (2026-06-05)

  • BREAKING We changed how logging works in our nm-shared branch of ds4, so there is now SetStderrFd rather than SetLogFunc.
  • Add lsp package for Language Server Protocol (LSP) support
  • Add webtool package for searching and querying web pages using Google Chrome.
  • Add ds4go web search and ds4go web visit CLI tools
  • Add ds4.DetectDefaultBackend
  • Add ds4.CaptureStderr(io.Writer) helper

v0.4.0 (2026-05-27)

  • Quick install script: curl -fsSL https://nimblemarkets.github.io/ds4go/install.sh | sh lands the CLI in /usr/local/bin with checksum verification
  • Added ds4go install --pin to use custom ds4 dynamic libraries.
  • Rearraged CLI with ds4go validate and ds4go status
  • libds4 power throttling: bind ds4_engine_power, ds4_engine_set_power, ds4_session_power, ds4_session_set_power, plus the new EngineOptions.PowerPercent field, for runtime GPU duty-cycle control (libds4 >= upstream commit 444afce / f398aa3)
  • libds4 display progress: bind ds4_session_set_display_progress as Session.SetDisplayProgress for UI-only fine-grained prefill progress (libds4 >= upstream commit fc1450d); distinct from SetProgress, must not be treated as a durable KV checkpoint boundary
  • libds4 vocab and logits: bind ds4_engine_vocab_size as Engine.VocabSize and ds4_session_copy_logits as Session.CopyLogits, both present in ds4.h since earlier releases but not previously bound
  • libds4 model identity & inspect: bind ds4_engine_model_name / ds4_engine_model_id as Engine.ModelName / Engine.ModelID, and add the EngineOptions.InspectOnly field (libds4 upstream commit 04f151d, DeepSeek V4 PRO support). ds4_context_memory_estimate now uses the active model shape, so an Engine.ContextMemoryEstimate method is provided alongside the package-level function
  • ds4go prompt --inspect now prints a Model: <name> (id=<id>) line after the libds4 summary, and passes InspectOnly=true so the engine open skips full generation-path prep
  • ds4go-steer status bar shows the active model name and id; startup also writes a Loaded model: … entry to the steer log file
  • PRO model catalog: add pro-imatrix, pro, and q2-q4-imatrix entries to the curated installer catalog, SHA256s pinned from Hugging Face X-Linked-Etag
  • fix: model downloads were returning HTTP 400 from HF's Xet CDN (cas-bridge.xethub.hf.co, which serves PRO and now all files in the repo). The CDN rejects open-ended (Range: bytes=N- or missing Range) GETs on large objects, and refuses any single Range that spans more than roughly 200 GiB. The downloader now always sends a closed Range and chunks fetches at 16 GiB so the 432 GiB PRO file streams successfully; resume from a .part file still works at any byte offset
  • fix: cEngineOptions was missing the power_percent field added in libds4 upstream commit 444afce; loading any libds4 built at or after that commit could silently corrupt the WarmWeights and Quality flags. The struct now matches ds4.h exactly
  • test: add gated (-tags ds4_integration) TestRealLibraryPowerRoundTrip that loads a real libds4 and round-trips a PowerPercent value — catches cEngineOptions ABI drift that mock-based tests cannot detect

v0.3.0 (2026-05-20)

  • DSML tool calling: end-to-end DSML encoder/decoder/dispatch, with an incremental StreamDecoder for live tool-call streaming and access to the final stream tool arguments
  • Install lifecycle: ds4go install now writes ds4go-install.json metadata, detects upgrades/replacements, and supports a new validate subcommand that checks permissions, SHA256, and dynamic dlopen
  • Uninstall command: ds4go uninstall cleanly removes the library, .sha256 sidecar, and metadata; reuses a new shared TUI confirm dialog
  • Engine logging: root logging helpers plus a libds4 log callback exposed through ds4api, with SetAbortFunc for fatal-invariant callbacks
  • ds4api serializes libds4 calls to avoid concurrent-entry hazards
  • CI now runs the full test suite under -race

v0.2.3 (2026-05-17)

  • feat: add Context for cancelation
  • feat: Access to Engine calls are syncronized by mutex, making access thread-safe

v0.2.0 (2026-05-17)

  • Developer ergonomic, module and package renaming!
  • Securty hardening
  • TUI love
  • GoReleaser-based releases with Homebrew tap (brew install nimblemarkets/tap/ds4go)

v0.1.0 (2026-05-16)

  • Initial release.
