 # Changelog
 
+## 0.1.3 (2026-02-19)
+
+### Features
+
+- add source line tracking for log parsing and validation
+- add unified filter module with expression-based log filtering
+- enhance comparison output with table formatting and JSON shorthand support
+- introduce CLI enhancements and output improvements
+- add support for config file via `--config` flag in CLI
+- improve filtering logic
+- add `generate-config` command with embedded templates for profile generation
+- ensure unique/unpaired entries are included in JSON and text diff outputs
+
+#### Improve CLI usability with new global flags:
+
+- Added `-j, --json` as shorthand for `-F json -c` for compact machine-readable output.
+- Added `-f, --filter` for unified filter expressions (for example: `c:core l:ERROR !t:timeout`).
+- `-f, --filter` can also be set with `LOG_ANALYZER_FILTER`.
+- `--json` conflicts with explicit `-F, --format` to avoid ambiguous output settings.
+
+#### Add configurable profiles and starter templates for custom log formats:
+
+- Added runtime profile loading via `--config <path>` or `LOG_ANALYZER_CONFIG`.
+- Parser markers, pairing markers, and correlation keys are now configurable through profiles.
+- Added profile-aware `info` insights for unknown components, commands, requests, and session prefixes.
+- Added reusable templates: `base`, `custom-start`, `service-api`, and `event-pipeline`.
+
+#### Improve `diff` output readability and diagnostics:
+
+- Differences are now classified as added, removed, or modified (`+`, `-`, `~`).
+- Summary output now includes counts of additions, removals, and modifications.
+- Diff entries now include source line numbers for faster navigation to original logs.
+- JSON diff output now includes `change_type`, and text diffs are split into `text1`/`text2`.
+
+#### Add profile generation command and built-in template support:
+
+- Added `generate-config` (`gen-config`) to create a TOML profile from a log file.
+- Generated profiles include discovered components, commands, requests, and session prefix hints.
+- Supports `--profile-name`, `--template`, and `-o, --output`.
+- `--template` now accepts either a file path or built-in template name (`base`, `custom-start`, `service-api`, `event-pipeline`).
+- Embedded built-in templates into the binary and use embedded `base` as default for better portability.
+
+#### Add unified filter expression syntax:
+
+- Added expression-based filtering via `-f, --filter`.
+- Supports `component`, `level`, `text`, and `direction` terms (with short aliases like `c:`, `l:`, `t:`, `d:`).
+- Supports exclusions with `!` (for example: `!l:DEBUG`).
+- Multiple terms are combined with AND semantics.
+- Matching for `level` and `direction` values is case-insensitive.
+- Unknown filter values now produce warnings to catch typos.
+
+### Fixes
+
+#### Fix regressions in compare/diff filtering and output:
+
+- Repeated shared keys are now paired one-to-one; unmatched occurrences are kept as unique entries.
+- `--sort-by time/component/level/type` now sorts correctly.
+- `--full` now prints full payload JSON in comparison output.
+- `-o, --output` now writes the correct output for `compare`, `diff`, `llm-diff`, `process`, and `perf` (text and JSON).
+- Filter logic is now consistent: different filter types are AND-ed, multiple values of the same type are OR-ed.
+- `diff` output now includes unpaired unique entries in both text and JSON modes.
+- Parser no longer panics when profile config has empty `command_payload_markers`.
+
+#### Improve output formatting for summaries:
+
+- Summary statistics now render as styled, width-aware tables.
+- Table formatting is applied consistently across console and file output.
+- Improves readability of command output for large result sets.
