Subject: ANN: Sequel 0.4.1 Released

Sequel version 0.4.1 has just been released. This release includes
error-handling in worker threads, support for DISTINCT ON clauses,
better support for database access using DBI and automatic adapter
loading.

Sequel is a lightweight ORM library for Ruby. Sequel provides thread
safety, connection pooling and a simple and expressive API for
constructing database queries and table schemas.

=== Changes in this release

* Improved error-handling for worker threads. Errors are saved to an
array and are accessible through #errors (#91).

  w = Sequel::Worker.new
  w.add {raise "blah blah"}
  w.join
  w.errors.first.message #=> "blah blah"

* Dataset#uniq/distinct can now accept a column list for DISTINCT ON
clauses.

  DB[:items].distinct(:category, price).sql
  #=> "SELECT DISTINCT ON (category, price) * FROM items"

* Added support for dbi-xxx URI schemes (#86).

  DB = Sequel.open 'dbi-pg://localhost/mydb'

* Put adapter files in lib/sequel/adapters. Requiring sequel/<adapter>
is now deprecated. Users can now just require 'sequel' and adapters
are automagically loaded (#93).

* Reorganized lib directory structure.

* Fixed problem in Database#uri where setting the password would raise
an error (#87).

* Improved Dataset#insert_sql to correctly handle string keys (#92).

* Fixed Model.all.

* Fixed literalization of strings with escape sequences in postgres
adapter (#90).

* Added support for literalizing BigDecimal values (#89).

* Fixed column qualification for joined datasets (thanks Christian).

* Implemented experimental informix adapter.
