0.2.0

completely refactored, improved and optimized persistence process and performance.
removed cascade remove functionality, refactored how cascades are working.
removed cascadeRemove option from relation options.
replaced cascadeAll with cascade: true syntax from relation options.
replaced cascadeInsert with cascade: ["insert"] syntax from relation options.
replaced cascadeUpdate with cascade: ["update"] syntax from relation options.
now when one-to-one or many-to-one relation is loaded and its not set (set to null) ORM returns you entity with relation set to null instead of undefined property as before.
now relation id can be set directly to relation, e.g. Post { @ManyToOne(type => Tag) tag: Tag|number } with post.tag = 1 usage.
now you can disable persistence on any relation by setting @OneToMany(type => Post, post => tag, { persistence: false }). This can dramatically improve entity save performance.
loadAllRelationIds method of QueryBuilder now accepts list of relation paths that needs to be loaded, also disableMixedMap option is now by default set to false, but you can enable it via new method parameter options
now returning and output statements of InsertQueryBuilder support array of columns as argument
now when many-to-many and one-to-many relation set to null all items from that relation are removed, just like it would be set to empty array
fixed issues with relation update from one-to-one non-owner side
now version column is updated on the database level, not by ORM anymore
now created date and update date columns is set on the database level, not by ORM anymore (e.g. using CURRENT_TIMESTAMP as a default value)
now InsertQueryBuilder, UpdateQueryBuilder and DeleteQueryBuilder automatically update entities after execution.
This only happens if real entity objects are passed.
Some databases (like mysql and sqlite) requires a separate query to perform this operation.
If you want to disable this behavior use queryBuilder.updateEntity(false) method.
This feature is convenient for users who have uuid, create/update date, version columns or columns with DEFAULT value set.
now InsertQueryBuilder, UpdateQueryBuilder and DeleteQueryBuilder call subscribers and listeners.
You can disable this behavior by setting queryBuilder.callListeners(false) method.
Repository and EntityManager method .findOneById is deprecated and will be removed in next 0.3.0 version.
Use findOne(id) method instead now.
InsertQueryBuilder now returns InsertResult which contains extended information and metadata about runned query
UpdateQueryBuilder now returns UpdateResult which contains extended information and metadata about runned query
DeleteQueryBuilder now returns DeleteResult which contains extended information and metadata about runned query
now insert / update / delete queries built with QueryBuilder can be wrapped into a transaction using useTransaction(true) method of the QueryBuilder.
insert, update and delete methods of QueryRunner now use InsertQueryRunner, UpdateQueryRunner and DeleteQueryRunner inside
removed deprecated removeById, removeByIds methods
removed deleteById method - use delete(id) method instead now
removed updateById method - use update(id) method instead now
changed snakeCase utility - check table names after upgrading
added ability to disable transaction in save and remove operations
added ability to disable listeners and subscribers in save and remove operations
added ability to save and remove objects in chunks
added ability to disable entity reloading after insertion and updation
class table inheritance functionality has been completely dropped
single table inheritance functionality has been fixed
@SingleEntityChild has been renamed to @ChildEntity
@DiscriminatorValue has been removed, instead parameter in @ChildEntity must be used, e.g. @ChildEntity("value")
@DiscriminatorColumn decorator has been removed, use @TableInheritance options instead now
skipSync in entity options has been renamed to synchronize. Now if it set to false schema synchronization for the entity will be disabled.
By default its true.
now array initializations for relations are forbidden and ORM throws an error if there are entities with initialized relation arrays.
@ClosureEntity decorator has been removed. Instead @Entity + @Tree("closure-table") must be used
added support for nested set and materialized path tree hierarchy patterns
breaking change on how array parameters work in queries - now instead of (:param) new syntax must be used (:...param).
This fixed various issues on how real arrays must work
changed the way how entity schemas are created (now more type-safe), now interface EntitySchema is a class
added @Unique decorator. Accepts custom unique constraint name and columns to be unique. Used only on as
composite unique constraint, on table level. E.g. @Unique("uq_id_name", ["id", "name"])
added @Check decorator. Accepts custom check constraint name and expression. Used only on as
composite check constraint, on table level. E.g. @Check("chk_name", "name <> 'asd'")
fixed Oracle issues, now it will be fully maintained as other drivers
implemented migrations functionality in all drivers
CLI commands changed from migrations:create, migrations:generate, migrations:revert and migrations:run to migration:create, migration:generate, migration:revert and migration:run
changed the way how migrations work (more info in #1315). Now migration table contains id column with auto-generated keys, you need to re-create migrations table or add new column manually.
entity schemas syntax was changed
dropped support for WebSql and SystemJS
@Index decorator now accepts synchronize option. This option need to avoid deleting custom indices which is not created by TypeORM
new flag in relation options was introduced: { persistence: false }. You can use it to prevent any extra queries for relations checks

added support for generated columns in MySQL
added support for ON UPDATE column option in MySQL
added SPATIAL and FULLTEXT index options in MySQL
added hstore and enum column types support in Postgres

isArray: boolean in ColumnOptions is deprecated. Use array: boolean instead.
deprecated removeById method, now use deleteById method instead.
added insert and delete methods into repository and entity manager.
fixed multiple issues with update, updateById and removeById methods in repository and entity manager. Now they do not use save and remove methods anymore - instead they are using QueryBuilder to build and execute their queries.
now save method can accept partial entities.
removed opencollective dependency.
fixed issues with bulk entity insertions.
find* methods now can find by embed conditions.
fixed issues with multiple schema support, added option to @JoinTable to support schema and database.

0.1.0

BREAKING CHANGES

Table, AbstractTable, ClassTableChild, ClosureTable, EmbeddableTable, SingleTableChild deprecated decorators were removed. Use Entity, ClassEntityChild, ClosureEntity, SingleEntityChild decorators instead.
EntityManager#create, Repository#create, EntityManager#preload, Repository#preload, EntityManager#merge, Repository#merge methods now accept DeepPartial<Entity> instead of Object.
EntityManager#merge, Repository#merge methods first argument is now an entity where to need to merge all given entity-like objects.
changed find* repository methods. Now conditions are Partial<Entity> type.
removed FindOptions interface and introduced two new interfaces: FindOneOptions and FindManyOptions - each for its own findOne* or find* methods.
dropped out some of options of FindOptions. Use QueryBuilder instead. However, added few new options as well.
deprecated method addParameters has been removed from QueryBuilder. Use setParameters instead.
removed setMaxResults, setFirstResult methods in QueryBuilder. Use take and skip methods instead.
renamed entityManager to manager in Connection, AbstractRepository and event objects. entityManager property was removed.
renamed persist to save in EntityManager and Repository objects. persist method was removed.
SpecificRepository is removed. Use relational query builder functionality instead.
transaction method has been removed from Repository. Use EntityManager#transaction method instead.
custom repositories do not support container anymore.
controller / subscriber / migrations from options tsconfig now appended with a project root directory
removed naming strategy decorator, naming strategy by name functionality. Now naming strategy should be registered by passing naming strategy instance directly.
driver section in connection options now deprecated. All settings should go directly to connection options root.
removed fromTable from the QueryBuilder. Now use regular from to select from tables.
removed usePool option from the connection options. Pooling now is always enabled.
connection options interface has changed and now each platform has its own set of connection options.
storage in sqlite options has been renamed to database.
env variable names for connection were changed (TYPEORM_DRIVER_TYPE has been renamed to TYPEORM_CONNECTION, some other renaming). More env variable names you can find in ConnectionOptionsEnvReader class.
some api changes in ConnectionManager and createConnection / createConnections methods of typeorm main entrypoint.
simple_array column type now is called simple-array
some column types were removed. Now orm uses column types of underlying database.
now number type in column definitions (like @Column() likes: number) maps to integer instead of double. This is more programmatic design. If you need to store float-pointing values - define a type explicitly.
fixedLength in column options has been removed. Now actual column types can be used, e.g. @Column("char") or @Column("varchar").
timezone option has been removed from column options. Now corresponding database types can be used instead.
localTimezone has been removed from the column options.
skipSchemaSync in entity options has been renamed to skipSync.
setLimit and setOffset in QueryBuilder were renamed into limit and offset.
nativeInterface has been removed from a driver interface and implementations.
now typeorm works with the latest version of mssql (version 4).
fixed how orm creates default values for SqlServer - now it creates constraints for it as well.
migrations interface has changed - now up and down accept only QueryRunner. To use Connection and EntityManager use properties of QueryRunner, e.g. queryRunner.connection and queryRunner.manager.
now update method in QueryBuilder accepts Partial<Entity> and property names used in update map are column property names and they are automatically mapped to column names.
SpecificRepository has been removed. Instead new RelationQueryBuilder was introduced.
getEntitiesAndRawResults of QueryBuilder has been renamed to getRawAndEntities.
in mssql all constraints are now generated using table name in their names - this is fixes issues with duplicate constraint names.
now when object is loaded from the database all its columns with null values will be set into entity properties as null. Also after saving entity with unset properties that will be stored as nulls - their (properties) values will be set to null.
create and update dates in entities now use date with fractional seconds.
@PrimaryGeneratedColumn decorator now accept generation strategy as first argument (default is increment), instead of column type. Column type must be passed in options object, e.g. @PrimaryGeneratedColumn({ type: "bigint"}).
@PrimaryColumn now does not accept generated parameter in options. Use @Generated or @PrimaryGeneratedColumn decorators instead.
Logger interface has changed. Custom logger supply mechanism has changed.
Now logging options in connection options is simple "true", or "all", or list of logging modes can be supplied.
removed driver section in connection options. Define options right in the connection options section.
Embedded decorator is deprecated now. use @Column(type => SomeEmbedded) instead.
schemaName in connection options is removed. Use schema instead.
TYPEORM_AUTO_SCHEMA_SYNC env variable is now called TYPEORM_SYNCHRONIZE.
schemaSync method in Connection has been renamed to synchronize.
getEntityManager has been deprecated. Use getManager instead.
@TransactionEntityManager is now called @TransactionManager now.
EmbeddableEntity, Embedded, AbstractEntity decorators has been removed. There is no need to use EmbeddableEntity and AbstractEntity decorators at all - entity will work as expected without them. Instead of @Embedded(type => X) decorator now @Column(type => X) must be used instead.
tablesPrefix, autoSchemaSync, autoMigrationsRun, dropSchemaOnConnection options were removed. Use entityPrefix, synchronize, migrationsRun, dropSchema options instead.

all table decorators are renamed to Entity (Table => Entity, AbstractTable => AbstractEntity,
ClassTableChild => ClassEntityChild, ClosureTable => ClosureEntity, EmbeddableTable => EmbeddableEntity,
SingleTableChild => SingleEntityChild). This change is required because upcoming versions of orm will work
not only with tables, but also with documents and other database-specific "tables".
Previous decorator names are deprecated and will be removed in the future.
added custom repositories support. Example in samples directory.

breaking changes in QueryBuilder:
- getSingleResult() renamed to getOne()
- getResults() renamed to getMany()
- getResultsAndCount() renamed to getManyAndCount()
- in the innerJoin/leftJoin methods now no need to specify ON
- in the innerJoin/leftJoin methods no longer supports parameters, use addParameters or setParameter instead.
