0.12 * Suppport for GHC 9 * Drop support for GHC 8.0 * Refactor test suite and migrate it to HSpec 0.11 * Suppport for GHC 8.8 * Drop support for GHC 7.* 0.10 * Pass type information along the UntypedExpr * Fix #57 (table indexes are ignored) 0.9.0 * Support for GHC 8.4 0.8.0.1 * New typeclass to allow transaction rollback through ExceptT 0.8 * Simplified signatures for PurePersistField and PrimitivePersistField * Basic support for streaming API * Support for GHC 8 0.7.0.3 * Add attoparsec dependency 0.7.0.2 * Bump blaze-builder dependency 0.7.0.1 * Support for monad-control 1.0 0.7.0 * Removed logger argument from executeMigration and runMigration * PersistField instance for lazy ByteString 0.6.0 * Entities without keys. It can be useful for many-to-many tables which hold keys but are not referenced * Entity and fields descriptions are parameterized so that they can be promoted * Entity and fields descriptions are dependent on database proxy. It allows to use different types depending on a database, for example, the same type can be array[] in PostgreSQL and varchar elsewhere * Migration support for indexes on expressions 0.5.1 * DISTINCT select option * Support entities with no fields * Added getCurrentSchema function into SchemaAnalyzer 0.5.0 * Reimplemented projections with constraint kinds * Moved QueryRaw constraint into class SqlDb simplifying SQL function signatures * Compatibility with GHC 7.8 0.4.2.2 * Create missing schemas (or databases in MySQL terminology) during migration * Replaced datatype Proxy with type variable 0.4.2 * Cond can be used as expression * Expressions instances for Fractional, Floating, Integral * Operator case_ 0.4.1 * Added functions replaceBy and deleteAll * Renamed deleteByKey to deleteBy * Instances of UTCTime and ZonedTime can read both values with time zone and without it 0.4.0.3 * Added function runDbConnNoTransaction to run a monadic action without creating a transaction around it 0.4.0.2 * Fix for nullable fields in unique constraint 0.4.0.1 * Added migration helper function Database.Groundhog.Generic.getQueries * Added comparison function Database.Groundhog.Expression.isFieldNothing 0.4.0 * References to tables not mapped by groundhog * Default column values * Better type inference for expressions * Constructor for empty condition CondEmpty * Logging queries based on monad-logger 0.3.1 * Removed superclass constraints SinglePersistField and PurePersistField for PrimitivePersistField * Fixed prefixing columns of nested embedded datatypes when not all names are specified 0.3 * Custom compositional functions and operators * ConnectionManager which helps to extract connections from pools, application state, etc. * Support for savepoints * Schema qualified tables * Added unique constraints of type PRIMARY * Reference clauses ON DELETE and ON UPDATE. * Exposed database introspection capabilities with class SchemaAnalyzer 0.2 * Database indexes * Support DB-specific column types * Renaming and refactoring 0.1.0.2 * Removed overly restrictive upper bound for bytestring package 0.1.0.1 * Compatibility with GHC 7.6 0.1.0 The library was almost completely overhauled. * Support for embedded datatypes * New syntax for select * Embedded datatypes * Composite foreign keys and natural keys * Projections of datatype fields * Codegeneration modules are moved to groundhog-th package 0.0.1 The first release. It has support for polymorphic datatypes and sum types.
