### Bug Fixes

- **migrate:** change rollback to match migrate behavior
  ([df5af9c](https://github.com/uptrace/bun/commit/df5af9c9cbdf54ce243e037bbb2c7b154f8422b3))

### Features

- added QueryBuilder interface for SelectQuery, UpdateQuery, DeleteQuery
  ([#499](https://github.com/uptrace/bun/issues/499))
  ([59fef48](https://github.com/uptrace/bun/commit/59fef48f6b3ec7f32bdda779b6693c333ff1dfdb))

# [1.1.2](https://github.com/uptrace/bun/compare/v1.1.2...v) (2022-03-22)

### Bug Fixes

  ([800616e](https://github.com/uptrace/bun/commit/800616ed28ca600ad676319a10adb970b2b4daf6))

### Features

  ([48b80e4](https://github.com/uptrace/bun/commit/48b80e4f7e3ed8a28fd305f7853ebe7ab984a497))

# [1.1.0](https://github.com/uptrace/bun/compare/v1.1.0-beta.1...v1.1.0) (2022-02-28)

### Features

- Added [MSSQL](https://bun.uptrace.dev/guide/drivers.html#mssql) support as a 4th fully supported
  DBMS.
- Added `SetColumn("col_name", "upper(?)", "hello")` in addition to
  `Set("col_name = upper(?)", "hello")` which works for all 4 supported DBMS.

* improve nil ptr values handling
  ([b398e6b](https://github.com/uptrace/bun/commit/b398e6bea840ea2fd3e001b7879c0b00b6dcd6f7))

### Breaking changes

- Bun no longer automatically marks some fields like `ID int64` as `pk` and `autoincrement`. You
  need to manually add those options:

```diff
type Model struct {
-	 ID int64
+	 ID int64 `bun:",pk,autoincrement"`
}
```

Bun [v1.0.25](#1024-2022-02-22) prints warnings for models with missing options so you are
recommended to upgrade to v1.0.24 before upgrading to v1.1.x.

- Also, Bun no longer adds `nullzero` option to `soft_delete` fields.

- Removed `nopk` and `allowzero` options.

### Bug Fixes

- append slice values
  ([4a65129](https://github.com/uptrace/bun/commit/4a651294fb0f1e73079553024810c3ead9777311))

  ([33b5b6f](https://github.com/uptrace/bun/commit/33b5b6ff660b77238a737a543ca12675c7f0c284))

## [1.0.25](https://github.com/uptrace/bun/compare/v1.0.23...v1.0.25) (2022-02-22)

### Bug Fixes

### Deprecated

In the comming v1.1.x release, Bun will stop automatically adding `,pk,autoincrement` options on
`ID int64/int32` fields. This version (v1.0.23) only prints a warning when it encounters such
fields, but the code will continue working as before.

To fix warnings, add missing options:

```diff
type Model struct {
-	 ID int64
+	 ID int64 `bun:",pk,autoincrement"`
}
```

To silence warnings:

```go
bun.SetWarnLogger(log.New(ioutil.Discard, "", log.LstdFlags))
```

Bun will also print a warning on [soft delete](https://bun.uptrace.dev/guide/soft-deletes.html)
fields without a `,nullzero` option. You can fix the warning by adding missing `,nullzero` or
`,allowzero` options.

In v1.1.x, such options as `,nopk` and `,allowzero` will not be necessary and will be removed.

### Bug Fixes

- fix missing autoincrement warning

  ([3b321b0](https://github.com/uptrace/bun/commit/3b321b08601c4b8dc6bcaa24adea20875883ac14))

### Breaking (MySQL, MariaDB)

- **insert:** get last insert id only with pk support auto increment
  ([79e7c79](https://github.com/uptrace/bun/commit/79e7c797beea54bfc9dc1cb0141a7520ff941b4d)). Make
  sure your MySQL models have `bun:",pk,autoincrement"` options if you are using autoincrements.

### Features
