This changelog summarizes new features and breaking changes in EdgeDB 1.0 beta 3 “Ross”.

We continue working on improving our schema and migration tools:

  • Prohibit mixing computed and regular links or properties (#2099).

  • Don’t ask for conversion expressions when changing type of computed link or property (#2658).

  • Fix some migration issues involving rebasing (#2536).

  • Fix backlink processing in SDL schemas (#1824).

  • Improve migration prompts (#2547, #2591).

  • Add free shapes (#2533).

    This construct provides a way to arbitrarily structure data without providing a specific underlying object. It is easier to package data that potentially contains empty sets this way, rather than using a tuple:

    Copy
    WITH U := (SELECT User FILTER .name LIKE '%user%')
    SELECT {
        matches := U {name},
        total := count(U),
        total_users := count(User),
    };
  • Add cal::relative_duration, which is similar to duration but instead uses fuzzy units like years, months and days in addition to the more standard units like seconds (#2559).

  • Enforce duration constraints in SQL as opposed to only during casting (#2539).

  • Implement path-like syntax for accessing enum types’ members (#2625):

    Copy
    SELECT Color.Red;

    is equivalent to

    Copy
    SELECT <Color>'Red';
  • Allow removal and reordering of enum elements (#2564).

  • Implement assert_single() which allows to perform a cardinality check in run-time (#2695):

    Copy
    db> 
    SELECT assert_single((SELECT User FILTER .name = "Unique"))
    {default::User {id: ...}}
    
    Copy
    db> 
    SELECT assert_single((SELECT User))
    ERROR: CardinalityViolationError: assert_single violation: more than
           one element returned by an expression
  • Adjust the precedence of DETACHED to match that of EXISTS (#2638).

    This makes it apply to shapes in a more intuitive fashion:

    Copy
    SELECT DETACHED User {
        exclamation := User.name ++ '!'
    }

    The above expression will now interpret the User inside that shape as the same DETACHED User as mentioned at the root of the shape.

  • Prohibit backlink syntax for computed links (#2619).

  • Prohibit “$” as the first character in identifiers (#2595).

  • Fix how ?? works with tuples (#2602).

  • Fix cardinality inference of computed links and properties (#2585).

  • Fix how DISTINCT applies to collections of shapes (#2540).

  • Fix some cases of nested UNLESS CONFLICT bugs (#2555).

  • Fix how nested volatile computed expressions get executed (#2545).

  • Fix how USING expressions propagate to subtypes (#2543).

  • Reflect json into a custom GraphQL type (#2782).

    The json values will be reflected into a custom JSON type that renders as seamless JSON. Assuming additional_data is a JSON value, here’s how a GraphQL query would work:

    Copy
    {
        Book {
            additional_data
        }
    }

    producing:

    Copy
    {
        "data": {
            "Book": [
                {
                    "additional_data": {
                        "dimensions": "6 x 8 in",
                        "# of illustrations": 5,
                        "illustrator": "Alice White"
                    }
                }
            ]
        }
    }

    There’s a limitation that in order for GraphQL type validation to work JSON values have to be passed as variables.

  • Remove the helper stdgraphql module as it is no loger needed (#2692).

  • Fix an issue with inline fragments (#1800).

We’ve implemented RFC 1008: TLS and ALPN. With Transport Layer Security (TLS) Protocol enabled by default, it is possible to leverage the TLS Application-Layer Protocol Negotiation (ALPN) Extension for secure and reliable protocol selection on top of the TLS transport, allowing EdgeDB to multiplex different frontend protocols like the binary protocol and the HTTP-based protocol on the same port.

We’ve changed some of the CLI commands and groupings. There are some top-level “frequently used” commands such as edgedb dump, edgedb restore, edgedb migrate, edgedb query, edgedb info and edgedb cli upgrade. Other commands are grouped into categories: edgedb configure, edgedb migration, edgedb list, edgedb describe, edgedb instance, edgedb project and edgedb server.

Here’s a more comprehensive list of the CLI commands:
