 # Changelog
 
+## 2025-11-02 - 2.7.0 - feat(tsbuild)
+Add tsconfig.json support and safer compiler option merging; protect critical options; apply path and enum transforms; bump dependencies.
+
+- Add robust tsconfig.json reading with graceful fallback when no tsconfig is present or it is invalid
+- Merge compiler options in a clear priority order (defaults -> tsconfig -> protected defaults -> programmatic -> CLI flags)
+- Introduce protected (critical) compiler options that cannot be overridden by tsconfig.json: outDir, noEmitOnError, declaration, emitDecoratorMetadata, inlineSourceMap
+- Convert string values from tsconfig (target, module, moduleResolution) to TypeScript enum values where applicable; special-case NodeNext
+- Transform tsconfig path mappings by replacing './ts_' with './dist_ts_' to keep runtime path resolution consistent with compiled output
+- Expose getCriticalDefaults helper and adjust mergeCompilerOptions to apply protected defaults before programmatic and CLI overrides
+- Update README with documentation for tsconfig support, merge order, protected compiler options, and example tsconfig
+- Bump dependencies/devDependencies: @push.rocks/smartcli ^4.0.19, @push.rocks/smartlog ^3.1.10, typescript 5.9.3, @git.zone/tsrun ^1.6.2, @git.zone/tstest ^2.7.0
+
+## 2025-08-29 - 2.6.8 - fix(tsbuild)
+Avoid process.exit in library, add confirmskiplibcheck flag, improve CLI exit handling and JSON/quiet modes, update test script
+
+- Changed package.json test script from "tsrun test/test.ts --verbose" to "tstest test/test.ts --verbose".
+- Library no longer calls process.exit from compile and compileWithErrorTracking; errors are returned or thrown so callers can decide process termination.
+- skipLibCheck behavior updated: delay/warning only happens when --confirmskiplibcheck is present; otherwise a short informational note is printed (suppressed in --quiet/--json).
+- CLI now awaits compileGlobStringObject calls and inspects a final error summary attached to argv to decide process.exit(1) when errors occurred.
+- compileGlobStringObject/exports now respect --quiet and --json modes, emit a JSON summary when --json is used, and attach the final error summary to argv so the CLI can determine exit behavior.
+
+## 2025-08-18 - 2.6.7 - fix(tspublish)
+Bump @git.zone/tspublish dependency to ^1.10.3
+
+- Updated dependency @git.zone/tspublish from ^1.10.2 to ^1.10.3 in package.json
+
+## 2025-08-18 - 2.6.6 - fix(dependencies)
+Update dependency @git.zone/tspublish to ^1.10.2
+
+- Bumped @git.zone/tspublish in package.json from ^1.10.1 to ^1.10.2
+
+## 2025-08-18 - 2.6.5 - fix(dependencies)
+Bump dependencies and add pnpm-workspace configuration
+
+- Updated @git.zone/tspublish from ^1.9.1 to ^1.10.1
+- Updated @push.rocks/smartfile from ^11.2.4 to ^11.2.7
+- Updated @push.rocks/smartpath from ^5.0.18 to ^6.0.0
+- Updated typescript from 5.8.3 to 5.9.2
+- Updated devDependency @git.zone/tstest from ^1.10.1 to ^2.3.4
+- Added pnpm-workspace.yaml with onlyBuiltDependencies list (esbuild, mongodb-memory-server, puppeteer)
+
+## 2025-05-24 - 2.6.4 - fix(dependencies)
+Add .npmrc and update dependency versions for smartfile and tstest
+
+- Add .npmrc with registry configuration for npm
+- Bump @push.rocks/smartfile version from ^11.2.3 to ^11.2.4
+- Bump @git.zone/tstest version from ^1.9.0 to ^1.10.1
+
+## 2025-05-21 - 2.6.3 - fix(tsbuild)
+minor maintenance updates and documentation improvements
+
+- Updated commit metadata to align with project version
+- Refined CLI command parsing and diagnostics logging for better clarity
+- Improved code readability in compiler options merging
+
+## 2025-05-21 - 2.6.2 - fix(npm configuration)
+Remove .npmrc file to default npm registry behavior
+
+- Deleted .npmrc file that hard-coded the npm registry URL to https://registry.npmjs.org/
+- This change leverages npm's default registry settings and reduces configuration clutter
+
+## 2025-05-21 - 2.6.1 - fix(tsbuild.classes)
+Improve error diagnostics handling by removing legacy helper and integrating more robust error summaries in the compilation process
+
+- Removed the handleDiagnostics method and its legacy usage
+- Replaced legacy calls with inline processDiagnostics checks for pre-emit and emit phases
+- Combined error summaries for clearer reporting during emit checks and type validation
+- Enhanced error output to guide users on resolving TypeScript errors before emission
+
+## 2025-05-21 - 2.6.0 - feat(tsbuild)
+Improve task logging and update dependencies
+
+- Add .npmrc file with npm registry configuration
+- Update test script to use '--verbose' flag
+- Bump dependency versions for @push.rocks packages and TypeScript
+- Enhance TsBuild logging by incorporating task info (e.g. task number, total tasks, output folder, and compile durations)
+- Propagate task info in compileFileArrayWithErrorTracking for better task tracking
+
+## 2025-05-21 - 2.5.2 - fix(tsbuild)
+Improve diagnostic error handling and summary reporting for TypeScript compilation by refactoring diagnostic processing and adding pre-emit error checks.
+
+- Introduce a dedicated processDiagnostics function that categorizes errors by file and computes error totals.
+- Refactor displayErrorSummary to provide clearer, color-coded output of error details.
+- Add pre-emit error checking in compileWithErrorTracking to prevent emission when errors exist.
+- Consolidate error summary merging in compileFileArrayWithErrorTracking for improved reporting.
+
+## 2025-05-15 - 2.5.1 - fix(commitinfo)
+Update commit information and metadata to synchronize release data
+
+- Regenerated the commitinfo file with current version details
+- Maintained existing functionality with no functional code changes
+
 ## 2025-05-15 - 2.5.0 - feat(cli)
 Enhance type checking in CLI by adding default file pattern handling

+## Configuration with tsconfig.json
+
+`@git.zone/tsbuild` fully supports `tsconfig.json` for compiler configuration. All compiler options from your `tsconfig.json` will be respected and merged with tsbuild's defaults.
+
+### Option Priority (Merge Order)
+
+When multiple configuration sources are present, they are merged in the following order (later sources override earlier ones):
+
+1. **Default compiler options** - Base defaults for all options
+2. **tsconfig.json** - All compiler options from your project's `tsconfig.json` (if present)
+3. **Protected defaults** - Critical options for build integrity (see below)
+4. **Programmatic options** - Options passed to API functions
+5. **CLI flags** - Command-line arguments (highest priority)
+
+### Protected Compiler Options
+
+To ensure build integrity and correct functionality, the following options are protected and cannot be overridden by `tsconfig.json` alone (but can be overridden programmatically or via CLI):
+
+- `outDir: 'dist_ts/'` - Required for path transformation logic
+- `noEmitOnError: true` - Prevents broken builds from being emitted
+- `declaration: true` - Ensures .d.ts files for library consumers
+- `emitDecoratorMetadata: true` - Required for dependency injection frameworks
+- `inlineSourceMap: true` - Provides consistent debugging experience
+
+### Working Without tsconfig.json
+
+`@git.zone/tsbuild` works perfectly fine without a `tsconfig.json` file. If no `tsconfig.json` is found, it will gracefully fall back to sensible defaults without errors.
+
+Example `tsconfig.json`:
+```json
+{
+  "compilerOptions": {
+    "experimentalDecorators": true,
+    "useDefineForClassFields": false,
+    "target": "ES2022",
+    "module": "NodeNext",
+    "moduleResolution": "NodeNext",
+    "esModuleInterop": true,
+    "verbatimModuleSyntax": true
+  }
+}
+```
