v0.3.0

Enhancements

• Support fragments in queries with the fragment(...) function
• Interpolated values in queries are now automatically cast. For example, from u in User, where: u.age > ^"10" will automatically cast "10" to an integer. Failing to cast will trigger an Ecto.CastError
• preload, lock and order_by now allow dynamic values
• Improve and relax type inference. Ecto no longer requires array(array, type), binary(...) and so on for interpolated values. In fact, the functions above have been removed

Backwards incompatible changes

• :virtual type no longer exists, instead pass virtual: true as field option
• Adapter API for insert, update and delete has been simplified

v0.2.8

Bug fixes

• Validation predicates now receive the attribute as first argument

v0.2.7

Enhancements

• Add support for Ecto.Model.Callbacks

Bug fixes

• Fix merging of validation errors when using validation_also

v0.2.6

Enhancements

• Log queries by default
• Pretty print queries (Inspect protocol implemented)

Bug fixes

• Cast primary key in Repo.get/2
• Use repository port in Mix tasks
• Fix type checking in Repo.update_all/2

Backwards incompatible changes

• Return validation errors as maps
• Fix belongs_to preload if no associated record exists

v0.2.5

Enhancements

• Change timeout of migration queries to infinity
• Add uuid type

Bug fixes

• Fix encoding of interpolated nil values
• Support interpolated large integers
• Support interpolating values on Repo.update_all
• Correctly handle nil values inside array/2 and binary/1

Backwards incompatible changes

• Do not translate foo == nil to the SQL foo IS NULL, provide is_nil/1 instead

v0.2.4

Enhancements

• Better error message if repo is not started
• Do not require ^ on literals inside array/2 or field/2
• Parametrize queries, interpolated values are no longer encoded as literals in the generated SQL query, instead they are sent as query parameters
• Allow starting the assoc selection from a joined association or building it from right outer joins

Bug fixes

• Remove possible deadlock for models using each other in queries

v0.2.3

Enhancements

• Add local and utc to Ecto.DateTime and Ecto.Date

Bug fixes

• Treat nil as an any data type
• Support array of binaries
• Avoid race conditions when optimizing query compilation

v0.2.2

Enhancements

• Do not require username and password to be present in parse_url/1

v0.2.1

Enhancements

• Add support for all query expressions in order_by, group_by and distinct expressions, instead of only allowing lists of fields
• Add Ecto.Model.scoped/2 as a shorthand for from(x in __MODULE__, ...)

Bug fixes

• Aggregate functions in order_by, distinct and select will make the query grouped

Backwards incompatible changes

• Single variables in group_by and distinct no longer expands to a list of fields

v0.2.0

Enhancements

• Add Ecto.Assocations.load/3 for loading associations
• Add Ecto.Model.primary_key/1 and Ecto.Model.put_primary_key/3 for accessing a model's primary key
• Add Ecto.Repo.one and Ecto.Repo.one! for running query expecting one result
• Add Ecto.Repo.get! that raises when receiving no result
• Set foreign key when loading belongs_to association to model

Bug fixes

• Ensure that existing primary key is not overwritten when inserting model
• Ecto.Repo.get no longer adds limit: 1 to query, it will now raise when receiving more than one result
• Properly underscore camelized names in associated models

Backwards incompatible changes

• Removed entities in favor of schema + structs. In particular, Ecto.Entity is gone as well as the queryable/2 macro. Instead developers should invoke schema/2 in their models, which will automatically define a struct in the current module. Now to create or update, developers should use struct(Post, []) or %Post{} instead of the previous Post.new([]) or Post[]
• Renamed has_many association function to_list to all
• Ecto.Repo.storage_down and Ecto.Repo.storage_up moved to Ecto.Storage
