# Changelog  
All notable changes to **GPT Exporter** will be documented in this file.

The project follows the structure of **Keep a Changelog**  
and **Semantic Versioning**, combined with human-friendly notes that reflect the real development process.

GPT Exporter is an offline-first desktop application built with a focus on simplicity, transparency, and extensibility.  
The project demonstrates how modern tools can accelerate development while keeping chat export processing local to the user’s machine.

## [0.1.1-nova] — Archive Compatibility Update
**Release date:** 2026-03-31

### Added
- Support for newer ChatGPT export archives that use `export_manifest.json`
- Support for sharded conversation files such as `conversations-000.json`, `conversations-001.json`, and similar
- Automatic fallback search for legacy `conversations.json` inside the unpacked archive
- Continued compatibility with older export archives based on a single `conversations.json`

### Changed
- Updated `export.py` to work with both old and new archive structures without changing the output format
- Export logic now detects conversation sources from the unpacked archive instead of relying only on root-level `conversations.json`
- Existing GUI workflow remains the same for the user
- Output format remains unchanged: one per-chat text-only JSON file for each conversation

### Fixed
- Fixed incompatibility with newer official ChatGPT export ZIP structures
- Fixed export flow for archives where conversations are split across multiple files
- Fixed exporter behavior so both legacy and newer exports are handled by the same build

### Notes
This release keeps the original Nova workflow and output format intact while improving compatibility with newer ChatGPT archive layouts.  
The goal of `0.1.1-nova` is to make the exporter more universal without changing the user-facing behavior of the application.

### Security
- Application performs no external network requests related to user data processing in the current version  
- All processing happens locally on the user’s machine  
- No telemetry or analytics by default
