- Updated session ID format documentation from nanoid to snowflake hex string format (16 hex characters).
- Removed nanoid dependency from package.json as it is now replaced by internal Snowflake implementation.
- Migrated environment variable access from direct process.env to centralized getEnv() utility function across all packages.
- Renamed environment variable prefix from OMP_ to PI_ throughout codebase (e.g., OMP_CODING_AGENT_DIR -> PI_CODING_AGENT_DIR).
- Removed automatic environment variable migration from PI_ to OMP_ prefixes via migrate-env.ts module.
- Removed env setting from configuration schema and applyEnvironmentVariables() method from settings.
- Updated CI/CD build configuration to use PI_COMPILED flag instead of OMP_COMPILED.
- Changed venvPath property in PythonRuntime from nullable (string | null) to optional (string | undefined).
- Added Grafana Pyroscope continuous profiling integration for CPU and heap profiling.
- Added seven new Pyroscope configuration settings: enabled, serverAddress, appName, basicAuthUser, basicAuthPassword, tenantID, and flushIntervalMs.
- Added support for Pyroscope configuration via environment variables: PYROSCOPE_URL, PYROSCOPE_APP_NAME, PYROSCOPE_BASIC_AUTH_USER, PYROSCOPE_BASIC_AUTH_PASSWORD, PYROSCOPE_TENANT_ID, and PYROSCOPE_FLUSH_INTERVAL_MS.
- Integrated Pyroscope initialization and shutdown into the main application lifecycle with automatic profiling start/stop.
- Added @pyroscope/nodejs dependency for continuous profiling capabilities.
- Migrated from Node.js to Bun runtime by replacing @types/node with @types/bun and bun-types dependencies.
- Downgraded @types/diff from ^8.0.0 to ^7.0.2 in coding-agent package.
- Updated tsconfig.base.json to include DOM.AsyncIterable in lib configuration for async iterable DOM API support.
- Simplified stream handling in update-cli.ts by removing Readable.fromWeb() conversions and using response.body directly with pipeline().
- Simplified TextDecoderStream instantiation in stream.ts to use default parameters instead of explicit UTF-8 encoding configuration.
- Added defensive null/undefined handling in agent-loop.ts result assignment using nullish coalescing operator.
- Updated @anthropic-ai/sdk from ^0.71.2 to ^0.72.1 in packages/ai.
