## 2.0.0 - pending

### New Features

* Role Based Access Control https://github.com/SeaQL/sea-orm/pull/2683

  1. a hierarchical RBAC engine that is table scoped
      + a user has 1 (and only 1) role
      + a role has a set of permissions on a set of resources
          + permissions here are CRUD operations and resources are tables
          + but the engine is generic so can be used for other things
      + roles have hierarchy, and so can inherit permissions
      + there is a wildcard `*` to grant all permissions or resources
      + individual users can have rules override
  3. a set of Entities to load / store the access control rules to / from database
  4. a query auditor that dissect queries for necessary permissions (implemented in SeaQuery)
  5. integration of RBAC into SeaORM in form of `RestrictedConnection`.
      it implements `ConnectionTrait`, and will audit all queries and perform permission check,
      and reject them accordingly. all Entity operations except raw SQL are supported.
      complex joins, insert select from, and even CTE queries are supported.
```rust
// load rules from database
db_conn.load_rbac().await?;

// admin can create bakery
let db = db_conn.restricted_for(admin)?;
let seaside_bakery = bakery::ActiveModel {
    name: Set("SeaSide Bakery".to_owned()),
    ..Default::default()
};
assert!(Bakery::insert(seaside_bakery).exec(&db).await.is_ok());

// public cannot create bakery
let db = db_conn.restricted_for(public)?;
assert!(matches!(
    Bakery::insert(bakery::ActiveModel::default())
        .exec(&db)
        .await,
    Err(DbErr::AccessDenied { .. })
));
```

* Overhauled `Entity::insert_many`. We've made a number of changes https://github.com/SeaQL/sea-orm/pull/2628
    1. removed APIs that can panic
    2. new helper struct `InsertMany`, `last_insert_id` is now `Option<Value>`
    3. on empty iterator, `None` or `vec![]` is returned on exec operations
    4. `TryInsert` API is unchanged

Previously, `insert_many` shares the same helper struct with `insert_one`, which led to an awkard API.
```rust
let res = Bakery::insert_many(std::iter::empty())
    .on_empty_do_nothing() // <- you need to add this
    .exec(db)
    .await;

assert!(matches!(res, Ok(TryInsertResult::Empty)));
```
`last_insert_id` is now `Option<Value>`:
```rust
struct InsertManyResult<A: ActiveModelTrait>
{
    pub last_insert_id: Option<<PrimaryKey<A> as PrimaryKeyTrait>::ValueType>,
}
```
Which means the awkardness is removed:
```rust
let res = Entity::insert_many::<ActiveModel, _>([]).exec(db).await;

assert_eq!(res?.last_insert_id, None); // insert nothing return None

let res = Entity::insert_many([ActiveModel { id: Set(1) }, ActiveModel { id: Set(2) }])
    .exec(db)
    .await;

assert_eq!(res?.last_insert_id, Some(2)); // insert something return Some
```
Same on conflict API as before:
```rust
let res = Entity::insert_many([ActiveModel { id: Set(3) }, ActiveModel { id: Set(4) }])
    .on_conflict_do_nothing()
    .exec(db)
    .await;

assert!(matches!(conflict_insert, Ok(TryInsertResult::Conflicted)));
```
Exec with returning now returns a `Vec<Model>`, so it feels intuitive:
```rust
assert!(
    Entity::insert_many::<ActiveModel, _>([])
        .exec_with_returning(db)
        .await?
        .is_empty() // no footgun, nice
);

assert_eq!(
    Entity::insert_many([
        ActiveModel {
            id: NotSet,
            value: Set("two".into()),
        }
    ])
    .exec_with_returning(db)
    .await
    .unwrap(),
    [
        Model {
            id: 2,
            value: "two".into(),
        }
    ]
);
```
* Improved utility of `ActiveModel::from_json`. Consider the following Entity https://github.com/SeaQL/sea-orm/pull/2599
```rust
#[derive(Clone, Debug, PartialEq, Eq, DeriveEntityModel, Serialize, Deserialize)]
#[sea_orm(table_name = "cake")]
pub struct Model {
    #[sea_orm(primary_key)]
    pub id: i32,      // <- not nullable
    pub name: String,
}
```
Previously, the following would result in error "missing field `id`":
```rust
assert!(
    cake::ActiveModel::from_json(json!({
        "name": "Apple Pie",
    })).is_err();
);
```
Now, the ActiveModel will be partially filled:
```rust
assert_eq!(
    cake::ActiveModel::from_json(json!({
        "name": "Apple Pie",
    }))
    .unwrap(),
    cake::ActiveModel {
        id: NotSet,
        name: Set("Apple Pie".to_owned()),
    }
);
```
* A full `Model` can now be used as `PartialModel` in nested query https://github.com/SeaQL/sea-orm/pull/2642
```rust
#[derive(DerivePartialModel)]
#[sea_orm(entity = "cake::Entity")]
struct Cake {
    id: i32,
    name: String,
    #[sea_orm(nested)]
    bakery: Option<bakery::Model>,
}

let cake: Cake = cake::Entity::find()
    .left_join(bakery::Entity)
    .order_by_asc(cake::Column::Id)
    .into_partial_model()
    .one(&ctx.db)
    .await?
    .unwrap();

assert_eq!(cake.id, 13);
assert_eq!(cake.name, "Cheesecake");
assert_eq!(
    cake.bakery.unwrap(),
    bakery::Model {
        id: 42,
        name: "cool little bakery".to_string(),
    }
);
```
* Wrapper type derived with `DeriveValueType` can now be used as primary key https://github.com/SeaQL/sea-orm/pull/2643
```rust
#[derive(Clone, Debug, PartialEq, Eq, DeriveEntityModel)]
#[sea_orm(table_name = "my_value_type")]
pub struct Model {
    #[sea_orm(primary_key)]
    pub id: MyInteger,
}

#[derive(Clone, Debug, PartialEq, Eq, DeriveValueType)]
pub struct MyInteger(pub i32);
// only for i8 | i16 | i32 | i64 | u8 | u16 | u32 | u64
```
* You can now define unique keys that span multiple columns in Entity https://github.com/SeaQL/sea-orm/pull/2651
```rust
#[derive(Clone, Debug, PartialEq, Eq, DeriveEntityModel)]
#[sea_orm(table_name = "lineitem")]
pub struct Model {
    #[sea_orm(primary_key)]
    pub id: i32,
    #[sea_orm(unique_key = "item")]
    pub order_id: i32,
    #[sea_orm(unique_key = "item")]
    pub cake_id: i32,
}

let stmts = Schema::new(backend).create_index_from_entity(lineitem::Entity);

assert_eq!(
    stmts[0],
    Index::create()
        .name("idx-lineitem-item")
        .table(lineitem::Entity)
        .col(lineitem::Column::OrderId)
        .col(lineitem::Column::CakeId)
        .unique()
        .take()
);

assert_eq!(
    backend.build(stmts[0]),
    r#"CREATE UNIQUE INDEX "idx-lineitem-item" ON "lineitem" ("order_id", "cake_id")"#
);
```
* Overhauled `ConnectionTrait` API: `execute`, `query_one`, `query_all`, `stream` now takes in SeaQuery statement instead of raw SQL statement https://github.com/SeaQL/sea-orm/pull/2657
```rust
// old
let query: SelectStatement = Entity::find().filter(..).into_query();
let backend = self.db.get_database_backend();
let stmt = backend.build(&query);
let rows = self.db.query_all(stmt).await?;

// new
let query: SelectStatement = Entity::find().filter(..).into_query();
let rows = self.db.query_all(&query).await?;
```
* Added `raw_sql` macro for ergonomic parameter injection
```rust
#[derive(FromQueryResult)]
struct Cake {
    name: String,
    #[sea_orm(nested)]
    bakery: Option<Bakery>,
}

#[derive(FromQueryResult)]
struct Bakery {
    #[sea_orm(alias = "bakery_name")]
    name: String,
}

let cake_ids = [2, 3, 4]; // expanded by the `..` operator

let cake: Option<Cake> = Cake::find_by_statement(raw_sql!(
    Sqlite,
    r#"SELECT "cake"."name", "bakery"."name" AS "bakery_name"
       FROM "cake"
       LEFT JOIN "bakery" ON "cake"."bakery_id" = "bakery"."id"
       WHERE "cake"."id" IN ({..cake_ids})"#
))
.one(db)
.await?;
```
* Added `consolidate` method to `SelectThree`. This output has different shape depending on the topology of the join.
```rust
// Order -> Customer
//       -> Lineitem

let items: Vec<(order::Model, Option<customer::Model>, Option<lineitem::Model>)> =
    order::Entity::find()
        .find_also_related(customer::Entity)
        .find_also_related(lineitem::Entity)
        .order_by_asc(order::Column::Id)
        .order_by_asc(lineitem::Column::Id)
        .all(&ctx.db)
        .await?;

// flat result
assert_eq!(
    items,
    vec![
        (order, Some(customer), Some(line_1)),
        (order, Some(customer), Some(line_2)),
    ]
);

let items: Vec<(order::Model, Vec<customer::Model>, Vec<lineitem::Model>)> =
    order::Entity::find()
        .find_also_related(customer::Entity)
        .find_also_related(lineitem::Entity)
        .order_by_asc(order::Column::Id)
        .order_by_asc(lineitem::Column::Id)
        .consolidate() // <-
        .all(&ctx.db)
        .await?;

// consolidated by order
assert_eq!(
    items,
    vec![(
        order,
        vec![customer],
        vec![line_1, line_2]
    )]
);

// Order -> Lineitem -> Cake
let items: Vec<(order::Model, Option<lineitem::Model>, Option<cake::Model>)> =
    order::Entity::find()
        .find_also_related(lineitem::Entity)
        .and_also_related(cake::Entity)
        .order_by_asc(order::Column::Id)
        .order_by_asc(lineitem::Column::Id)
        .all(&ctx.db)
        .await?;

// flat result
assert_eq!(
    items,
    vec![
        (order, Some(line_1), Some(cake_1)),
        (order, Some(line_2), Some(cake_2)),
    ]
);

let items: Vec<(order::Model, Vec<(lineitem::Model, Vec<cake::Model>)>)> =
    order::Entity::find()
        .find_also_related(lineitem::Entity)
        .and_also_related(cake::Entity)
        .order_by_asc(order::Column::Id)
        .order_by_asc(lineitem::Column::Id)
        .consolidate() // <-
        .all(&ctx.db)
        .await?;

// consolidated by order first, then by line
assert_eq!(
    items,
    vec![(
        order,
        vec![(line_1, vec![cake_1]), (line_2, vec![cake_2])]
    )]
);
```
* Added `Select::has_related`
```rust
// cake -> fruit: find all cakes containing mango
assert_eq!(
    cake::Entity::find()
        .has_related(fruit::Entity, fruit::Column::Name.eq("Mango"))
        .build(DbBackend::Sqlite)
        .to_string(),
    [
        r#"SELECT "cake"."id", "cake"."name" FROM "cake""#,
        r#"WHERE EXISTS(SELECT 1 FROM "fruit""#,
        r#"WHERE "fruit"."name" = 'Mango'"#,
        r#"AND "cake"."id" = "fruit"."cake_id")"#,
    ]
    .join(" ")
);
// cake -> cake_filling -> filling: find all cakes with orange fillings
assert_eq!(
    cake::Entity::find()
        .has_related(filling::Entity, filling::Column::Name.eq("Marmalade"))
        .build(DbBackend::Sqlite)
        .to_string(),
    [
        r#"SELECT "cake"."id", "cake"."name" FROM "cake""#,
        r#"WHERE EXISTS(SELECT 1 FROM "filling""#,
        r#"INNER JOIN "cake_filling" ON "cake_filling"."filling_id" = "filling"."id""#,
        r#"WHERE "filling"."name" = 'Marmalade'"#,
        r#"AND "cake"."id" = "cake_filling"."cake_id")"#,
    ]
    .join(" ")
);
```

### Enhancements

* [sea-orm-cli] Added `--column-extra-derives` https://github.com/SeaQL/sea-orm/pull/2212
* Added `Model::try_set`
* Added new error variant `BackendNotSupported`. Previously, it panics with e.g. "Database backend doesn't support RETURNING" https://github.com/SeaQL/sea-orm/pull/2630
```rust
let result = cake::Entity::insert_many([])
    .exec_with_returning_keys(db)
    .await;

if db.support_returning() {
    // Postgres and SQLite
    assert_eq!(result.unwrap(), []);
} else {
    // MySQL
    assert!(matches!(result, Err(DbErr::BackendNotSupported { .. })));
}
```
* Added new error variant `PrimaryKeyNotSet`. Previously, it panics with "PrimaryKey is not set" https://github.com/SeaQL/sea-orm/pull/2627
```rust
assert!(matches!(
    Update::one(cake::ActiveModel {
        ..Default::default()
    })
    .exec(&db)
    .await,
    Err(DbErr::PrimaryKeyNotSet { .. })
));
```
* Remove panics in `Schema::create_enum_from_active_enum` https://github.com/SeaQL/sea-orm/pull/2634
```rust
fn create_enum_from_active_enum<A>(&self) -> Option<TypeCreateStatement>
// method can now return None
```
* Added `ColumnTrait::eq_any` as a shorthand for the ` = ANY` operator. Postgres only.
```rust
assert_eq!(
    cake::Entity::find()
        .filter(cake::Column::Id.eq_any(vec![4, 5]))
        .build(DbBackend::Postgres)
        .to_string(),
    r#"SELECT "cake"."id", "cake"."name" FROM "cake" WHERE "cake"."id" = ANY(ARRAY [4,5])"#
);
```
* Added `ActiveModelTrait::try_set`
```rust
pub trait ActiveModelTrait {
    /// old: set the Value of a ActiveModel field, panic if failed
    fn set(&mut self, c: <Self::Entity as EntityTrait>::Column, v: Value) {
        self.try_set(c, v).unwrap_or_else(|e| panic!(..))
    }

    /// new: same as above but non-panicking
    fn try_set(&mut self, c: <Self::Entity as EntityTrait>::Column, v: Value) -> Result<(), DbErr>;
}
```
* `Linked` can now be used in partial select, in case `Related` cannot be defined
```rust
pub struct ToBakery;
impl Linked for ToBakery {
    type FromEntity = super::cake::Entity;
    type ToEntity = super::bakery::Entity;

    fn link(&self) -> Vec<RelationDef> {
        vec![Relation::Bakery.def()]
    }
}

#[derive(Debug, DerivePartialModel)]
#[sea_orm(entity = "cake::Entity", into_active_model)]
struct Cake2 {
    id: i32,
    name: String,
    #[sea_orm(nested, alias = "r0")]
    bakery: Option<Bakery>,
    #[sea_orm(skip)]
    ignore: Ignore,
}

let cake2: Cake2 = cake::Entity::find()
    .left_join_linked(ToBakery)
    .order_by_asc(cake::Column::Id)
    .into_partial_model()
    .one(&ctx.db)
    .await?
    .unwrap();
```
* `RelationDef` now implements `Clone`. `on_condition` is changed to `Arc` but this is a minor breaking change.

### Breaking Changes

Please read [SeaQuery's breaking changes](https://github.com/SeaQL/sea-query/blob/master/CHANGELOG.md#breaking-changes) as well. But for most compile errors, you can simply add `use sea_orm::ExprTrait;` in scope.
```rust

* Removed `runtime-actix` feature flag. It's been an alias of `runtime-tokio` for more than a year, so there should be no impact.
* Enabled `sqlite-use-returning-for-3_35` by default. SQLite `3.35` was released in 2021, it should be the default by now.
* Now implemented `impl<T: ModelTrait + FromQueryResult> PartialModelTrait for T`, there may be a potential conflict https://github.com/SeaQL/sea-orm/pull/2642
* Now `DeriveValueType` will also `TryFromU64` if applicable, there may be a potential conflict https://github.com/SeaQL/sea-orm/pull/2643
* Added `TryIntoModel` and `Serialize` to trait bounds of `ActiveModel::from_json`. There should be no impact if your models are derived with `DeriveEntityModel` https://github.com/SeaQL/sea-orm/pull/2599
```rust
fn from_json(mut json: serde_json::Value) -> Result<Self, DbErr>
where
    Self: TryIntoModel<<Self::Entity as EntityTrait>::Model>,
    <<Self as ActiveModelTrait>::Entity as EntityTrait>::Model: IntoActiveModel<Self>,
    for<'de> <<Self as ActiveModelTrait>::Entity as EntityTrait>::Model:
        serde::de::Deserialize<'de> + serde::Serialize,
```
* `DerivePartialModel` now implement `FromQueryResult` by default, so there may be a potential conflict. Remove `FromQueryResult` in these cases https://github.com/SeaQL/sea-orm/pull/2653
```rust
error[E0119]: conflicting implementations of trait `sea_orm::FromQueryResult` for type `CakeWithFruit`
  |
> | #[derive(DerivePartialModel, FromQueryResult)]
  |          ------------------  ^^^^^^^^^^^^^^^ conflicting implementation for `CakeWithFruit`
```
* Changed `IdenStatic` and `EntityName` definition https://github.com/SeaQL/sea-orm/pull/2667
```rust
trait IdenStatic {
    fn as_str(&self) -> &'static str; // added static lifetime
}
trait EntityName {
    fn table_name(&self) -> &'static str; // added static lifetime
}
```
* Removed `DeriveCustomColumn` and `default_as_str` https://github.com/SeaQL/sea-orm/pull/2667
```rust
// This is no longer supported:
#[derive(Copy, Clone, Debug, EnumIter, DeriveCustomColumn)]
pub enum Column {
    Id,
    Name,
}

impl IdenStatic for Column {
    fn as_str(&self) -> &str {
        match self {
            Self::Name => "my_name",
            _ => self.default_as_str(),
        }
    }
}

// Do the following instead:
#[derive(Copy, Clone, Debug, EnumIter, DeriveColumn)]
pub enum Column {
    Id,
    #[sea_orm(column_name = "my_name")]
    Name,
}
```
* `execute`, `query_one`, `query_all`, `stream` now takes in SeaQuery statement instead of raw SQL statement. a new set of methods `execute_raw`, `query_one_raw`, `query_all_raw`, `stream_raw` is added https://github.com/SeaQL/sea-orm/pull/2657
```rust
  --> src/executor/paginator.rs:53:38
   |
>  |         let rows = self.db.query_all(stmt).await?;
   |                            --------- ^^^^ expected `&_`, found `Statement`
   |                            |
   |                            arguments to this method are incorrect
   |
   = note: expected reference `&_`
                 found struct `statement::Statement`
```
```rust
let backend = self.db.get_database_backend();
let stmt = backend.build(&query);
// change to:
let rows = self.db.query_all_raw(stmt).await?;
// if the query is a SeaQuery statement, then just do this:
let rows = self.db.query_all(&query).await?; // no need to build query
```
* `DatabaseConnection` is changed from enum to struct. The original enum is moved into `DatabaseConnection::inner`. The new enum is named `DatabaseConnectionType` https://github.com/SeaQL/sea-orm/pull/2671
```rust
error[E0599]: no associated item named `Disconnected` found for struct `db_connection::DatabaseConnection` in the current scope
   --> src/database/db_connection.rs:137:33
    |
>   | pub struct DatabaseConnection {
    | ----------------------------- associated item `Disconnected` not found for this struct
...
>   |             DatabaseConnection::Disconnected => Err(conn_err("Disconnected")),
    |                                 ^^^^^^^^^^^^ associated item not found in `DatabaseConnection`
```
```rust
match conn.inner {
    DatabaseConnectionType::Disconnected => (),
    _ => (),
}
```
* `DeleteOne` and `UpdateOne` no longer implement `QueryFilter` and `QueryTrait`
  directly. Those implementations could expose an incomplete SQL query with an
  incomplete condition that touches too many records. To generate the right
  condition, we must make sure that the primary key is set on the input
  `ActiveModel`. If you need to access the generated SQL query, convert into
  `ValidatedDeleteOne`/`ValidatedUpdateOne` first.
```rust
error[E0599]: no method named `build` found for struct `query::update::UpdateOne` in the current scope
   --> src/entity/column.rs:607:22
    |
  > | /                 Update::one(active_model)
  > | |                     .build(DbBackend::Postgres)
    | |                     -^^^^^ method not found in `UpdateOne<A>`
    | |_____________________|
    |
```
Call the `validate()` method:
```rust
Update::one(active_model)
  + .validate()?
    .build(DbBackend::Postgres)
```
* Removed `DbBackend::get_query_builder()` because `QueryBuilder` is not longer object safe.
```rust
  - fn get_query_builder(&self) -> Box<dyn QueryBuilder>
```
* A number of methods has been removed from `SelectTwoMany`: `into_partial_model`, `into_json`, `stream`. These methods are same as those in `SelectTwo`.
Please use `Cake::find().find_also_related(Fruit).into_json()` instead.

## 1.0.1 - 2024-08-26

### New Features

* Added `ConnectOptions::connect_lazy` for creating DB connection pools without establishing connections up front https://github.com/SeaQL/sea-orm/pull/2268

### Breaking Changes

* Changed `ProxyDatabaseTrait` methods to async. It's a breaking change, but it should have been part of the 1.0 release.
    The feature is behind the feature guard `proxy`, and we believe it shouldn't impact majority of users.

        .expect_err("Insert a row with invalid foreign key")
        .sql_err(),
    Some(SqlErr::ForeignKeyConstraintViolation(_))
));
```
* Added `Select::find_with_linked`, similar to `find_with_related`: https://github.com/SeaQL/sea-orm/pull/1728, https://github.com/SeaQL/sea-orm/pull/1743
```rust
fn find_with_related<R>(self, r: R) -> SelectTwoMany<E, R>

assert_eq!(migrations.len(), 5);

let migration = migrations.get(0).unwrap();
assert_eq!(migration.name(), "m20220118_000002_create_fruit_table");
assert_eq!(migration.status(), MigrationStatus::Pending);
```
* The `postgres-array` feature will be enabled when `sqlx-postgres` backend is selected https://github.com/SeaQL/sea-orm/pull/1565
* Replace `String` parameters in API with `Into<String>` https://github.com/SeaQL/sea-orm/pull/1439
    * Implements `IntoMockRow` for any `BTreeMap` that is indexed by string `impl IntoMockRow for BTreeMap<T, Value> where T: Into<String>`

```rust
|db: DatabaseConnection| {
    assert!(db.ping().await.is_ok());
    db.clone().close().await;
    assert!(matches!(db.ping().await, Err(DbErr::ConnectionAcquire)));
}
```
* Added `TryInsert` that does not panic on empty inserts https://github.com/SeaQL/sea-orm/pull/1708
```rust
// now, you can do:
let res = Bakery::insert_many(std::iter::empty())
    .on_empty_do_nothing()
    .exec(db)
    .await;

assert!(matches!(res, Ok(TryInsertResult::Empty)));
```
* Insert on conflict do nothing to return Ok https://github.com/SeaQL/sea-orm/pull/1712
```rust
let on = OnConflict::column(Column::Id).do_nothing().to_owned();

// Existing behaviour
let res = Entity::insert_many([..]).on_conflict(on).exec(db).await;
assert!(matches!(res, Err(DbErr::RecordNotInserted)));

// New API; now you can:
let res =
Entity::insert_many([..]).on_conflict(on).do_nothing().exec(db).await;
assert!(matches!(res, Ok(TryInsertResult::Conflicted)));
```

### Bug Fixes

* Fixed `DeriveActiveEnum` throwing errors because `string_value` consists non-UAX#31 compliant characters https://github.com/SeaQL/sea-orm/pull/1374
```rust
#[derive(EnumIter, DeriveActiveEnum)]
#[sea_orm(rs_type = "String", db_type = "String(None)")]
pub enum StringValue {
    #[sea_orm(string_value = "")]
    Member1,
    #[sea_orm(string_value = "$$")]
    Member2,
}
// will now produce the following enum:
pub enum StringValueVariant {
    __Empty,
    _0x240x24,
}
```
* [sea-orm-cli] Fix Postgres enum arrays https://github.com/SeaQL/sea-orm/pull/1678
* [sea-orm-cli] The implementation of `Related<R>` with `via` and `to` methods will not be generated if there exists multiple paths via an intermediate table https://github.com/SeaQL/sea-orm/pull/1435
* [sea-orm-cli] fixed entity generation includes partitioned tables https://github.com/SeaQL/sea-orm/issues/1582, https://github.com/SeaQL/sea-schema/pull/105
* Fixed `ActiveEnum::db_type()` return type does not implement `ColumnTypeTrait` https://github.com/SeaQL/sea-orm/pull/1576
* Resolved `insert_many` failing if the models iterator is empty https://github.com/SeaQL/sea-orm/issues/873

### Breaking changes

* Supports for partial select of `Option<T>` model field. A `None` value will be filled when the select result does not contain the `Option<T>` field instead of throwing an error. https://github.com/SeaQL/sea-orm/pull/1513
* Replaced `sea-strum` dependency with upstream `strum` in `sea-orm` https://github.com/SeaQL/sea-orm/pull/1535
    * Added `derive` and `strum` features to `sea-orm-macros`
    * The derive macro `EnumIter` is now shipped by `sea-orm-macros`
* Added a new variant `Many` to `Identity` https://github.com/SeaQL/sea-orm/pull/1508
* Enabled `hashable-value` feature in SeaQuery, thus `Value::Float(NaN) == Value::Float(NaN)` would be true https://github.com/SeaQL/sea-orm/pull/1728, https://github.com/SeaQL/sea-orm/pull/1743
* The `DeriveActiveEnum` derive macro no longer implement `std::fmt::Display`. You can use the new `DeriveDisplay` macro https://github.com/SeaQL/sea-orm/pull/1726
* `sea-query/derive` is no longer enabled by `sea-orm`, as such, `Iden` no longer works as a derive macro (it's still a trait). Instead, we are shipping a new macro `DeriveIden` https://github.com/SeaQL/sea-orm/pull/1740 https://github.com/SeaQL/sea-orm/pull/1755
```rust
// then:

#[derive(Iden)]
#[iden = "category"]
pub struct CategoryEnum;

#[derive(Iden)]
pub enum Tea {
    Table,
    #[iden = "EverydayTea"]
    EverydayTea,
}

// now:

#[derive(DeriveIden)]
#[sea_orm(iden = "category")]
pub struct CategoryEnum;

#[derive(DeriveIden)]
pub enum Tea {
    Table,
    #[sea_orm(iden = "EverydayTea")]
    EverydayTea,
}
```
* Definition of `DbErr::ConnectionAcquire` changed to `ConnectionAcquire(ConnAcquireErr)` https://github.com/SeaQL/sea-orm/pull/1737
* `FromJsonQueryResult` removed from entity prelude

* Noop when update without providing any values https://github.com/SeaQL/sea-orm/pull/1384
    * Fixes Syntax Error when saving active model that sets nothing https://github.com/SeaQL/sea-orm/pull/1376

### Breaking Changes

* [sea-orm-cli] Enable --universal-time by default https://github.com/SeaQL/sea-orm/pull/1420
* Added `RecordNotInserted` and `RecordNotUpdated` to `DbErr`
* Added `ConnectionTrait::execute_unprepared` method https://github.com/SeaQL/sea-orm/pull/1327
* As part of https://github.com/SeaQL/sea-orm/pull/1311, the required method of `TryGetable` changed:
```rust
// then
fn try_get(res: &QueryResult, pre: &str, col: &str) -> Result<Self, TryGetError>;
// now; ColIdx can be `&str` or `usize`
fn try_get_by<I: ColIdx>(res: &QueryResult, index: I) -> Result<Self, TryGetError>;
```
So if you implemented it yourself:
```patch
impl TryGetable for XXX {
-   fn try_get(res: &QueryResult, pre: &str, col: &str) -> Result<Self, TryGetError> {
+   fn try_get_by<I: sea_orm::ColIdx>(res: &QueryResult, idx: I) -> Result<Self, TryGetError> {
-       let value: YYY = res.try_get(pre, col).map_err(TryGetError::DbErr)?;
+       let value: YYY = res.try_get_by(idx).map_err(TryGetError::DbErr)?;
        ..
    }
}
```
* The `ActiveModelBehavior` trait becomes async trait https://github.com/SeaQL/sea-orm/pull/1328.
If you overridden the default `ActiveModelBehavior` implementation:
```rust
#[async_trait::async_trait]
impl ActiveModelBehavior for ActiveModel {
    async fn before_save<C>(self, db: &C, insert: bool) -> Result<Self, DbErr>
    where
        C: ConnectionTrait,
    {
        // ...
    }

    // ...
}
```
* `DbErr::RecordNotFound("None of the database rows are affected")` is moved to a dedicated error variant `DbErr::RecordNotUpdated` https://github.com/SeaQL/sea-orm/pull/1425
```rust
let res = Update::one(cake::ActiveModel {
        name: Set("Cheese Cake".to_owned()),
        ..model.into_active_model()
    })
    .exec(&db)
    .await;

// then
assert_eq!(
    res,
    Err(DbErr::RecordNotFound(
        "None of the database rows are affected".to_owned()
    ))
);

// now
assert_eq!(res, Err(DbErr::RecordNotUpdated));
```
* `sea_orm::ColumnType` was replaced by `sea_query::ColumnType` https://github.com/SeaQL/sea-orm/pull/1395
    * Method `ColumnType::def` was moved to `ColumnTypeTrait`
    * `ColumnType::Binary` becomes a tuple variant which takes in additional option `sea_query::BlobSize`
    * `ColumnType::Custom` takes a `sea_query::DynIden` instead of `String` and thus a new method `custom` is added (note the lowercase)
```diff
// Compact Entity
#[derive(Clone, Debug, PartialEq, Eq, DeriveEntityModel)]
#[sea_orm(table_name = "fruit")]
pub struct Model {
-   #[sea_orm(column_type = r#"Custom("citext".to_owned())"#)]
+   #[sea_orm(column_type = r#"custom("citext")"#)]
    pub column: String,
}
```
```diff
// Expanded Entity
impl ColumnTrait for Column {
    type EntityName = Entity;

    fn def(&self) -> ColumnDef {
        match self {
-           Self::Column => ColumnType::Custom("citext".to_owned()).def(),
+           Self::Column => ColumnType::custom("citext").def(),
        }
    }
}
```

* `SelectTwoMany::one()` has been dropped https://github.com/SeaQL/sea-orm/pull/813, you can get `(Entity, Vec<RelatedEntity>)` by first querying a single model from Entity, then use [`ModelTrait::find_related`] on the model.
* #### Feature flag revamp
    We now adopt the [weak dependency](https://blog.rust-lang.org/2022/04/07/Rust-1.60.0.html#new-syntax-for-cargo-features) syntax in Cargo. That means the flags `["sqlx-json", "sqlx-chrono", "sqlx-decimal", "sqlx-uuid", "sqlx-time"]` are not needed and now removed. Instead, `with-time` will enable `sqlx?/time` only if `sqlx` is already enabled. As a consequence, now the features `with-json`, `with-chrono`, `with-rust_decimal`, `with-uuid`, `with-time` will not be enabled as a side-effect of enabling `sqlx`.

* Returning by @billy1624 in https://github.com/SeaQL/sea-orm/pull/292

### Breaking Changes
* Refactor `paginate()` & `count()` utilities into `PaginatorTrait`. You can use the paginator as usual but you might need to import `PaginatorTrait` manually when upgrading from the previous version.
    ```rust
    use futures::TryStreamExt;
    use sea_orm::{entity::*, query::*, tests_cfg::cake};

    let mut cake_stream = cake::Entity::find()
        .order_by_asc(cake::Column::Id)
        .paginate(db, 50)
        .into_stream();

    while let Some(cakes) = cake_stream.try_next().await? {
        // Do something on cakes: Vec<cake::Model>
    }
    ```
* The helper struct `Schema` converting `EntityTrait` into different `sea-query` statements now has to be initialized with `DbBackend`.
    ```rust
    use sea_orm::{tests_cfg::*, DbBackend, Schema};
    use sea_orm::sea_query::TableCreateStatement;

    // 0.3.x
    let _: TableCreateStatement = Schema::create_table_from_entity(cake::Entity);

    // 0.4.x
    let schema: Schema = Schema::new(DbBackend::MySql);
    let _: TableCreateStatement = schema.create_table_from_entity(cake::Entity);
    ```
* When performing insert or update operation on `ActiveModel` against PostgreSQL, `RETURNING` clause will be used to perform select in a single SQL statement.
    ```rust
    // For PostgreSQL
    cake::ActiveModel {
        name: Set("Apple Pie".to_owned()),
        ..Default::default()
    }
    .insert(&postgres_db)
    .await?;

    assert_eq!(
        postgres_db.into_transaction_log(),
        vec![Transaction::from_sql_and_values(
            DbBackend::Postgres,
            r#"INSERT INTO "cake" ("name") VALUES ($1) RETURNING "id", "name""#,
            vec!["Apple Pie".into()]
        )]);
    ```
    ```rust
    // For MySQL & SQLite
    cake::ActiveModel {
        name: Set("Apple Pie".to_owned()),
        ..Default::default()
    }
    .insert(&other_db)
    .await?;

    assert_eq!(
        other_db.into_transaction_log(),
        vec![
            Transaction::from_sql_and_values(
                DbBackend::MySql,
                r#"INSERT INTO `cake` (`name`) VALUES (?)"#,
                vec!["Apple Pie".into()]
            ),
            Transaction::from_sql_and_values(
                DbBackend::MySql,
                r#"SELECT `cake`.`id`, `cake`.`name` FROM `cake` WHERE `cake`.`id` = ? LIMIT ?"#,
                vec![15.into(), 1u64.into()]
            )]);
    ```
