Oh My Pi v18.4.9 Release Notes — What's New

Fixed rejected HTTP 400 requests from consuming unbounded disk space by automatically cleaning up old request logs and enforcing a size limit.
Fixed unnecessary credential and session updates that could trigger needless authentication reloads in other running processes.
Fixed context-overflow recovery for Strata requests that exceed the model context limit but return no usage information.

Fixed model catalog caching so unchanged catalogs refresh without unnecessary rewrites, and offline snapshots for endpoint-less models (such as Azure models) are now handled correctly across startups.

Added opt-in stale-session garbage collection with omp gc --stale or gc.stale, removing orphaned session markers and terminal breadcrumbs and expiring old debug reports and collaboration replicas according to configurable retention limits.
Added RPC controls to cancel or steer individual foreground and background subagents without aborting the session.
Added RPC word-completion commands so web and IDE hosts can provide the same ghost-text completion available in the terminal editor.
Added an opt-in RPC ask-dialog mode that lets hosts render all questions together with checkbox or radio-button controls and submit their answers in one response.
Added SDK notifications when a session moves to a new persistence file, including the previous and new paths.
Added SDK APIs to inspect and cancel background jobs, including their command, working directory, process IDs, exit status, and captured output.

Improved the omp predict comparison view with an interactive native interface, table rows, action controls, and clearer status information.
Improved MCP authorization prompts with clickable links, native copy/open context menus, and a clearer URL layout.
RPC hosts are now notified when omp cancels an expired select, confirm, input, or ask dialog, allowing stale UI prompts to be closed.
Limited saved bash, Python, and JavaScript evaluation output artifacts to 16 MB by default while preserving both the beginning and latest output; configure the limit with tools.artifactMaxBytes, or set it to 0 for unlimited output.

Fixed /wt on filesystems without copy-on-write cloning, including NTFS, so unchanged files are not incorrectly marked modified and staged edits, additions, and deletions retain the correct contents.
Fixed Windows Ctrl+V taking about a second to paste by avoiding unnecessary PowerShell clipboard checks.
Fixed local:// paths being misinterpreted as local filesystem paths by the read, write, and search tools.
Fixed read handling of semicolon-separated URLs, local paths, and line selectors so each entry is processed independently.
Fixed session persistence conflicts between multiple omp processes, preventing lost or interleaved turns and continuing in a new session file when necessary.
Fixed session image handling to avoid unnecessary rewrites, preserve images after interrupted writes, and prevent garbage collection from removing images that are referenced again.
Reduced unnecessary disk writes and improved persistence efficiency across sessions, model data, configuration, and background jobs.
Fixed the native composer showing the main session's effort level instead of the selected subagent's level.
Fixed the omp predict comparison view and MCP authorization prompt rendering with their full native interfaces, including clickable link actions.

Added readTextFromClipboard() for reading plain text from the system clipboard without starting a subprocess.
Added Shell.pids() to retrieve the IDs of still-running processes spawned by an in-flight shell command.

Exported wordCompletionQuery() so hosts outside the editor can apply the same prose eligibility rules used by ghost-text word completion.
Added a full-featured Background jobs view with selectable jobs, live status and elapsed time, working directory, process IDs, exit code, command, tailing output, and cancellation for running jobs.

OutputSink now limits artifact files to 16 MiB by default while preserving the beginning and end of oversized output and marking the omitted bytes. Set artifactMaxBytes: 0 to keep artifacts unbounded; dump() reports omitted bytes and full-output references identify sampled artifacts.

Reduced unnecessary composer startup-cache writes and ensured the cache database is released when it closes on Windows.
Fixed Shift+Enter and Ctrl+Enter prompt behavior in Windows Terminal 1.24 and earlier; Shift+Enter now inserts a newline and Ctrl+Enter sends a follow-up, matching other platforms.
Improved the Tern native terminal experience across background jobs, settings, debugging, logs, extension management, interactive shell, and provider streams: views remain usable and navigable, preserve output and selection behavior, support keyboard scrolling, and keep key actions accessible.
Fixed multi-line labels in Background jobs and multi-line titles in native-terminal prompts so their formatting remains readable.

Added tryAcquireFileLock, a non-blocking file-lock helper that returns null when the lock is already held.
Added an unref option to AsyncDrain, allowing applications to use long batch windows without keeping the process alive.

Improved logging efficiency and configurability by batching routine file writes, flushing urgent records promptly, adding on-demand logger.flush() support, and allowing file log levels to be limited with OMP_LOG_LEVEL. Log files are created only when needed, and obsolete log and audit files are cleaned up automatically.

Added terminal scrolling support through the TSP scroll operation, allowing keyboard scrolling of the terminal scroller when supported.
Added a terminal focus event for requesting keyboard focus on editors and inputs, or returning focus to the preferences sheet.
