What's New

Sandbox.Close / SandboxManager.Close now return error to satisfy io.Closer. Callers that previously ignored the return value need to update signatures (and ideally check the returned error). Same PR also drains HTTP response bodies after read so the underlying connection is reused, replaces manual url.QueryEscape with url.Values, drops the deprecated crypto/dsa import + DSA public-key branch, and trims unused go.mod dependencies. (#851)
TLS 1.2 minimum for SDK-created HTTP clients, enforcing the NIST 2030 minimum certificate key/hash length policy. Environments still serving TLS 1.0/1.1 endpoints must upgrade before adopting this release. Compatibility escape hatches are exposed for legacy weaker certificates. (#790)

Multi-file upload: new UploadFiles helper on Sandbox performs multipart uploads against execd's existing /files/upload multi-file contract. The single-file UploadFile is now a thin wrapper over the batch path. /files/download remains single-file streaming, so no DownloadFiles counterpart is added. (#843)
User-Agent header (OpenSandbox-Go-SDK/1.0.1) is now set on every outgoing request — doRequestOnce, doStreamRequest, GetCommandLogs, UploadFiles, DownloadFile. (#850)

Forward all GetEndpoint headers on subsequent execd/egress requests, matching the Python SDK. The previous code only forwarded X-EXECD-ACCESS-TOKEN / OPENSANDBOX-EGRESS-AUTH and dropped everything else, breaking routing whenever the server added new headers (sticky-session keys, routing hints, etc.). Closes #886. (#900)
Empty SSE stream now surfaces an error instead of silently returning a "successful but empty" Execution (stdout=[], stderr=[], results=[], error=nil, complete=nil). streamSSE() now counts dispatched events and returns opensandbox: empty sse stream when the body closes with zero events, so transport/proxy/execd failures stop masquerading as successful executions. (#778)
