v1.3.2

Fixed

• GetFullOutputAsync now captures stdout/stderr faithfully — exact line endings and any trailing newline are preserved instead of being normalized to the host newline and truncated. GetBytesOutputAsync's captured StdErr is likewise faithful. (ToResultAsync, which reads the line-oriented handle, remains line-normalized — its XML doc now says so and points to the faithful helpers.)

v1.3.1

Added

• ProcessGroupOptions (ShutdownTimeout, EscalateToKill) and a ProcessGroup(ProcessGroupOptions) constructor to tune the Unix SIGTERM grace window and force-kill escalation. Ignored on Windows, where the Job Object terminates members atomically.
• ProcessRunOptions.ProcessGroupOptions (configures the private group the runner creates) and ProcessRunOptions.PumpTeardownTimeout (bounds how long handle disposal waits for the output pumps).
• ProcessRunner(ProcessRunOptions defaults) constructor: baseline options applied to every call, with per-call options overriding field-by-field (the environment is unioned, per-call key winning).
• Interactive standard input: ProcessRunOptions.KeepStandardInputOpen keeps stdin open after start and exposes IRunningProcess.StandardInput (IProcessStandardInput: WriteAsync/WriteLineAsync/FlushAsync/CompleteAsync) for write-then-read (REPL) processes. The bulk helpers force it off.
• A BenchmarkDotNet project (benchmarks/ProcessKit.Benchmarks) measuring process start/exit overhead, bulk-capture shapes, streaming throughput, and per-line pump cost. Not part of the package or CI.

Changed

• ProcessRunOptions.WorkingDirectory and ProcessRunOptions.Environment now apply to every overload (and are inherited from ProcessRunner defaults), taking precedence over the supplied ProcessStartInfo; previously they affected only the convenience Start(executable, arguments, …) overloads.

v1.3.0

Added

• ProcessRunOptions.OutputBuffer (OutputBufferPolicy with OutputOverflowMode) caps how many unconsumed stdout/stderr lines are buffered, with a non-blocking drop-oldest/drop-newest policy — closing the OOM risk on chatty processes whose output is never consumed.
• IRunningProcess.ToResultAsync(...) extension drains an already-started handle into a ProcessResult<string>.
• IRunningProcess.CompletionOrThrowAsync(...) extension awaits the exit code but throws TimeoutException when the process was killed by ProcessRunOptions.Timeout.
• ProcessRunOptions.WorkingDirectory and ProcessRunOptions.Environment set the working directory and environment for the convenience Start(executable, arguments, …) overloads.

Changed

• GetExitCodeAsync now discards stdout/stderr by default (memory-flat) instead of buffering it unboundedly, since it never exposes the output. Supply an OutputBuffer policy to override.
• GetBytesOutputAsync now throws OperationCanceledException when the caller's CancellationToken is cancelled, consistent with GetFullOutputAsync; a Timeout still returns a partial result with WasTimedOut set.

Fixed

• Standard input is now always closed at start when no StandardInput is supplied, matching the documented contract. Previously the child inherited the parent's stdin, so a process that reads stdin (e.g. cat) could block forever when run with no input.
• The defensive ProcessStartInfo clone now mirrors the caller's environment exactly. Previously an environment variable removed from ProcessStartInfo.Environment could reappear in the started process, because the clone was seeded with the current process environment and never cleared.
• A user-supplied stdin source (FromStream/FromLines/FromEnumerable) that throws no longer lets the exception escape from IRunningProcess.DisposeAsync; the failure is contained and the child receives whatever was written before it, then EOF.
• IRunningProcess.CpuTime and PeakMemoryBytes now refresh the underlying counters before sampling, so repeated live reads report current values instead of a stale first-read snapshot.

v1.2.0

Added

• IProcessRunner interface and ProcessRunner default implementation for executing external commands with full lifetime management via ProcessGroup.
• ProcessRunner.Default static singleton for casual use without DI.
• IRunningProcess handle exposing StdOut/StdErr as IAsyncEnumerable<string>, line counters, Pid, StartTime, Duration, CpuTime, PeakMemoryBytes, WasTimedOut, Exited cancellation token, and Completion task.
• ProcessResult<T> record carrying StdOut, StdErr, ExitCode, WasTimedOut, IsSuccess, and fluent EnsureSuccess().
• ProcessExitException raised by EnsureSuccess() on non-zero exit, carrying ExitCode and the captured StdErr.
• ProcessRunOptions (record) for stdin, stderr/stdout handlers, shared ProcessGroup, timeout, and encoding overrides.
• StandardInput closed union with factories Empty, FromString, FromBytes, FromStream, FromLines (async), FromEnumerable (sync), and FromFile (eagerly validated path).
• Extension methods on IProcessRunner: Start(exe, args) convenience overload, GetOutputAsync, GetFirstLineOutputAsync, GetFullOutputAsync, GetBytesOutputAsync, GetExitCodeAsync, sync GetOutput/GetFirstLineOutput, and Task<ProcessResult<T>>.EnsureSuccessAsync().

Changed

• README slimmed for the NuGet package page: contributor-only "Running tests on Linux from Windows" guide moved to docs/linux-testing.md.
• README intro and NuGet package description rewritten to reflect both surfaces (ProcessGroup lifetime layer + ProcessRunner async-first command runner).
