+# qbolt
+
+A graphical database manager for BoltDB.
+
+QBolt allows you to graphically view and edit the content of Bolt databases.
+
+The project consists of two parts; a C binding (CGo) for the embeddable Bolt database engine, and a graphical interface built in C++/Qt that links to it.
+
+Written in C++ (Qt), Golang (CGo)
+
+## Features
+
+- Open existing database or create new database
+- Option to open database as readonly for concurrent use
+- Create, list, edit and delete keys and buckets (including nested buckets)
+- Safe for use with arbitrary binary key/bucket names (new ones created in UTF-8)
+- View database and bucket statistics
+- 100% Bolt compatibility via the real codebase
+- Tested working on both Windows and Linux
+
+## License
+
+Source code content of `qbolt-x.x.x-src.tar.gz` is released under the ISC license.
+BoltDB is released under the MIT license.
+The Windows binary is released under LGPL-3+ owing to the static copy of Qt.
+
+## See also
+
+- BoltDB https://github.com/boltdb/bolt
+
+## Changelog
+
+2020-04-12 1.0.2
+- Rebuild artefacts with etcd-io/bbolt v1.3.5, go 1.15, Qt 5.15, and new GCC versions
+- Switch from hg to Git
+- Use Go modules
+- Add support for building Windows binary in Docker
+- [⬇ Download here](https://git.ivysaur.me/code.ivysaur.me/qbolt/releases/tag/v1.0.2)
+
+2017-06-19 1.0.1
+- Feature: Option to open database as read-only
+- Fix an issue with support for bucket names and keys not surviving UTF-8 roundtrips (now binary-clean)
+- Fix an issue with crashing when deleting a bucket other than the selected one
+- Fix a cosmetic issue with application icon on Windows
+- [⬇ Download here](https://git.ivysaur.me/code.ivysaur.me/qbolt/releases/tag/v1.0.1)
+
+2017-05-21 1.0.0
+- Initial public release
