- Separated non-contiguous diff regions with a single blank gap row, normalized after block-context insertion.
- Rendered gap rows as one dim ellipsis in the TUI and HTML export.
- Applied the same blank-separator dedupe and edge-trimming to hashline's compact diff preview.
- Exported hashline section interfaces and helpers, including a new section-diff API for external callers.
- Refactored `computeHashlineDiff` to split input sections, propagate split errors, and delegate each section via helper.
- Added context-highlight caching and batched highlighting for unchanged lines, with `replaceTabs` fallback on unknown files.
- Fixed hashline streaming preview so completed sections stay visible when a new `@PATH` header appears mid-stream.
- Added hashline streaming tests for section persistence, malformed trailing `+ 7`, and dual sections.
- Added sanitizeText to edit renderer previews and diff rendering before line processing.
- Passed filePath into replaceTabs calls across edit previews, errors, and diff visualization paths.
- Added `CodeFrameMarker` and `formatCodeFrameLine()` to centralize code-frame gutter formatting.
- Extended diff rendering to preserve `|` and `│` separators, aligning gutter markers and line numbers.
- Reworked AST, grep, hashline, Vim, and diff renderers to use shared line formatting with computed `lineNumberWidth`.
- Updated atom editing flow and tests, including `resolveAtomEntryPaths` migration and new loc-based/edge-case coverage.
- Adjusted benchmark runner early-stop configuration by passing `buildEarlyStop` through prompt collection.
- Expanded hashline and chunk bigram tables to 647 entries and moved chunk checksums to a 40-item namespace.
- Changed hashline anchors from `LINE#ID`/`:` to concatenated `LINEID`\t forms across parsing and tool outputs.
- Removed line-number padding and routed diff/read/grep/renderer output through raw numbers, tabs, and `toDisplayLine` formatting.
- Renamed atom ops to `pre`/`post`, removed `ins`, and updated schemas, prompts, and tests for new insertion behavior.
- Extracted tab width resolution from pi-natives to pi-utils with EditorConfig caching support.
- Made tabWidth parameter required in native text functions (visibleWidth, truncateToWidth, wrapTextWithAnsi, sliceWithWidth, extractSegments).
- Removed process-wide tab width state management from pi-natives text module.
- Consolidated wrapper node promotion logic in chunk classification with abbreviated string representations.
- Removed path-clean and pathdiff dependencies from pi-natives.
- Updated all consuming packages to import tab width functions from pi-utils and pass explicit tabWidth parameters.
- Migrated native bindings from TypeScript wrappers to NAPI-RS generated modules with auto-generated type definitions and runtime enums.
- Replaced chunk tree API with stateful ChunkState class supporting render, edit, and resolve operations with improved error handling.
- Converted callback signatures to error-first pattern (error, result) for shell, PTY, glob, and grep operations.
- Introduced type-safe enums for MacOSAppearance, GrepOutputMode, KeyEventType, ImageFormat, and AstMatchStrictness replacing string literals.
- Refactored chunk tree implementation with dedicated modules for edit, indent, resolve, and state management with comprehensive validation.
- Moved clipboard utilities from native bindings to coding-agent package with improved OSC 52 and Termux compatibility.
- Added a `display.tabWidth` setting to control default tab rendering.
- Integrated `.editorconfig` resolution for c ontext-aware tab indentation.
- Updated native text processing to use the resolved tab width for calculations.
- Improved tab visualization in diffs and other UI elements for consistency.
- Added PTY (pseudo-terminal) backed interactive command execution with streaming output support via PtySession class in pi-natives.
- Added PtyStartOptions and PtyRunResult types to configure and report PTY session execution status.
- Added write(), resize(), and kill() methods to PtySession for interactive control of running commands.
- Added interactive bash execution via PTY with real-time terminal rendering and input forwarding in bash-interactive tool.
- Added --no-pty CLI flag and PI_NO_PTY environment variable to disable PTY-based interactive bash execution.
- Added bash.virtualTerminal setting to control PTY-backed interactive execution behavior.
- Renamed XML tag `<important>` to `<caution>` across system prompts and tool documentation for improved semantic clarity.
- Collapsed multi-line function calls to single lines in diff component formatting for improved code conciseness.
- Consolidated emoji guideline into critical section in write tool documentation.
- Fixed whitespace visualization in CHANGELOG diff output and corrected incomplete text.
- Added visualization of leading whitespace (indentation) in diff output with dim glyphs--tabs display as ` -> ` and spaces as `·` for improved readability.
- Implemented visualizeIndent() function to normalize and display indentation patterns, collapsing 3-space groups into tab arrows and marking individual spaces with middle dots.
- Removed getCursorPosition() method from Component interface and implementations, eliminating hardware cursor positioning support.
- Changed PI_HARDWARE_CURSOR environment variable default from implicit true to explicit '1' with fallback pattern.
- Changed PI_CLEAR_ON_SHRINK environment variable default from implicit false to explicit '0' with fallback pattern.
- Added screen clearing on TUI startup to prevent shell prompts from bleeding into first rendered frame.
- Refactored full-render logic into reusable fullRender() helper function.
- Removed WASM generation script; use Bun `wasm?raw` loader for imports.
- Added bunfig.toml with loaders for `.md`, `.py`, and `.wasm?raw` text imports.
- Added types/assets/index.d.ts for global TypeScript module declarations.
- Unified TypeScript configuration with tsgo-based checking across monorepo.
- Removed build and WASM steps from install and publish pipelines.
- Added tsconfig.publish.json files to all packages with optimized publish-time configuration.
- Updated all package.json scripts with prepublishOnly hooks for correct type checking during publish.
- Added @oh-my-pi/omp-stats path mappings to root tsconfig.json for consistent imports.
- Added WASM generation script for photon module and integrated into install:dev script.
