-
-### Added
-
-- **Compression Module** (`stegasoo.compression`)
-  - Zlib compression for payloads (enabled by default)
-  - Optional LZ4 support for faster compression (`pip install lz4`)
-  - Automatic algorithm detection on decompression
-  - `--compress/--no-compress` CLI flags
-  - `--algorithm` flag to choose compression method
-  - `estimate_compressed_size()` for capacity planning
-
-- **Batch Processing** (`stegasoo.batch`)
-  - `stegasoo batch encode` - encode message into multiple images
-  - `stegasoo batch decode` - decode from multiple images
-  - `stegasoo batch check` - check capacity of multiple images
-  - Parallel processing with configurable workers (`-j/--jobs`)
-  - Recursive directory scanning (`-r/--recursive`)
-  - Progress callbacks for UI integration
-  - JSON output for all batch operations
-
-- **CLI Improvements**
-  - `--json` global flag for machine-readable output
-  - `--dry-run` flag for encode (preview capacity usage)
-  - `stegasoo info` command to show version and features
-  - JSON output for `generate` command
-
-- **New Constants**
-  - `MIN_COMPRESS_SIZE` - minimum size to attempt compression
-  - `ZLIB_COMPRESSION_LEVEL` - compression level setting
-  - `BATCH_DEFAULT_WORKERS` - default parallel workers
-  - `BATCH_MAX_WORKERS` - maximum parallel workers
-
-### Changed
-
-- Version bumped to 2.2.0
-- Payloads are now compressed by default before encryption
-- Updated `pyproject.toml` with `compression` optional dependency group
-
-### Dependencies
-
-- Added optional dependency: `lz4>=4.0.0` (in `[compression]` extra)
-
-## [2.1.4] - 2025-12-29
-
-### Changed
-
-- Centralized all configuration values to `constants.py`
-- Added version injection to Flask templates via context processor
-- Synchronized version across `constants.py` and `pyproject.toml`
-
-## [2.1.3] - 2025-12-28
-
-### Added
-
-- Initial public release
-- Core steganography encoding/decoding
-- Hybrid authentication (passphrase + PIN)
-- RSA key support
-- QR code credential sharing
-- CLI interface
-- REST API (FastAPI)
-- Web frontend (Flask)
-- File payload embedding
-- Temporary file auto-expiry
