This patch release fixes a bug shipped in v0.7.6 that assets deprecation warning pops up even though the assets flag is not provided.

The long anticipated release brings a lot of bug fixes and some performance improvements, especially for KV backends.

Highlights

Backends

• New SQLite backend (#751).
• KV and NoSQL backends migrated to Hidalgo.
• Initial import to KV backends should be much faster now (#803).

Query languages

• A new Order() iterator and corresponding method for Gizmo (#796).
• Set of changes to Gizmo to make it more Gremlin-compatible (#822, #849, #859).
• Gizmo can now emit JSON-LD via HTTP API if appropriate Accept header is set (#821).

Bug fixes

• A lot of bug fixes for queries, backends, etc. See the full changelog for details.

Go library

• Switched to Go modules.
• Quads package split to it's own repository.

Breaking changes

• The query.Session interface changed to be more user-friendly.

Note: Cayley haven't reached 1.0 yet, thus you should pin a specific version in go.mod to avoid breaking changes. We try hard to minimize those.

This release brings multiple stability fixes and adds initial support for cyclic objects to the schema lib.

Highlights

Fixes

• Fix bug when deleted a reinserted quad in KV backends (@3pCode, #747).
• Fix Optional iterator not propagating own tags (@phyrwork, #739).
• Update BoomFilter to avoid panic (@hypirion, #744).

Library

• schema: Support loading and writing objects containing loops (#745, #746).
• schema: Fix recursive ID lookup in anonymous fields (@phyrwork, #733).
• New Resolver iterator (@phyrwork, #741).
• Add RefsOf to BatchQuadStore interface (@phyrwork, #742).

As always, we expect Go users to pin a specific Cayley version tag with dep.

This release fixes few bugs and adds label support for the schema lib.

Highlights

• Schema lib now allows adding a label to all written quads (1a0c7cb)
• Fixed a bug with KV backend that allowed to write duplicate quads in the same TX (#675)
• All() query for nodes now honors a query limit (#718). Previous behavior can be achieved by passing ?limit=-1 parameter.
