+# Changelog
+
+All notable changes to DocLoom CLI will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [0.2.0] - 2025-10-15
+
+### 🎉 Added
+- **Batch Analysis**: New `analyze-batch` command processes multiple files with `[N/Total]` progress
+- **Mixed-Input Batch**: Supports `.csv`, `.tsv`, `.xlsx` (analyzed) + `.yaml`, `.md`, `.txt`, `.docx` (added as docs)
+- **Project-Level Sample Control**: `--sample-rows-project` flag to override samples in all summaries (set `0` to disable)
+- **Memory Safety**: Hard limits prevent OOM (200k tokens, 20 summaries per project)
+- **Context Validation**: Blocks oversized prompts for local LLMs with actionable error messages
+- **Timeout Configuration**: `--timeout-sec` flag for generation requests (default 180s)
+- **TSV Auto-Delimiter**: Automatically sets tab delimiter for `.tsv` files
+
+### 🐛 Fixed
+- **CRITICAL**: XLSX parser returning 0 columns due to absolute relationship paths in ZIP archives
+- Unbounded memory accumulation with multiple large files (9.3GB → <2GB peak)
+- Duplicate document detection (no more silent overwrites)
+- Memory leaks in outlier computation
+- Context window overflow causing silent truncation in Ollama
+- RAG chunker producing oversized chunks exceeding token limits
+- Prompt instruction duplication (40% token reduction)
+- Dataset summary basename collisions with disambiguation logic
+- Invalid `--sheet-name` silently falling back to first sheet
+
+### ⚡ Performance
+- Reduced memory usage by 78% for multi-file projects
+- Batched embedding prevents API timeout failures (100 chunks/batch)
+- 40% reduction in prompt tokens via deduplication
+- Immediate memory release after outlier computation
+
+### 💥 Breaking Changes
+- Context overflow now **blocks** execution for Ollama (was warning-only)
+- Duplicate files now **error** instead of silently overwriting
+- Invalid `--sheet-name` now errors with available sheet list
+- Projects enforce maximum 200k token limit (hard cap at 200k)
+- Maximum 20 dataset summaries per project (prevents context bloat)
+
+### 📚 Documentation
+- Added [docs/examples/analyze-batch.md](cci:7://file:///home/jeremiah/Projects/docloom-cli/docs/examples/analyze-batch.md:0:0-0:0) with batch processing examples
+- Updated README with mixed-input batch behavior
+- Added XLSX parser fix details and regression test
+- Updated quickstart with batch analysis tips
+
+### 🧪 Testing
+- Added regression test for XLSX relationship path normalization
+- Added integration test for batch analysis with sample suppression
+- Memory profiling tests ensure <2GB peak for 10x100k-row files
+- Race detector clean across all packages
+
+## [0.1.0] - 2025-10-01
+
+### Added
+- Initial release
+- Basic project management (`init`, `add`, `list`)
+- CSV/TSV/XLSX analysis with schema inference
+- OpenRouter, Ollama, and major provider support
+- RAG with embedding indexes
+- Model catalog management

 - Behavior in projects: When you `add` CSV/TSV/XLSX to a project, the parser stores a summary (not the raw table) to keep prompts concise and token‑efficient.
 - Standalone analysis: Use `docloom analyze <file>` to generate a report and optionally save it to a file or attach it to a project with `-p`.
 
+Batch analysis with progress
+
+- Use `docloom analyze-batch "data/*.csv"` (supports globs) to process multiple files with `[N/Total]` progress.
+- Supports mixed inputs: `.csv`, `.tsv`, `.xlsx` are analyzed; other formats (`.yaml`, `.md`, `.txt`, `.docx`) are added as regular documents when `-p` is provided.
+- When attaching (`-p`), you can override sample rows for all summaries using `--sample-rows-project`. Set it to `0` to disable sample tables in reports.
+- When writing summaries into a project (`dataset_summaries/`), filenames are disambiguated:
+  - If `--sheet-name` is used, the sheet slug is included: `name__sheet-sales.summary.md`
+  - On collision, a numeric suffix is appended: `name__2.summary.md`
+

 - `--print-prompt`: prints the prompt even for real runs.
 - `--prompt-limit N`: truncates the built prompt to N tokens before sending.
+- `--timeout-sec N`: sets the request timeout (default 180 seconds).
 - `--budget-limit USD`: fails early if estimated max cost (prompt + max-tokens) exceeds the budget.
 - `--quiet`: suppresses non-essential console output.
 - `--json`: emit response as JSON to stdout.
