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).

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

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

- Put adapter files in lib/sequel/adapters. Requiring sequel/  
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.
