0.9.2

The main, highly awaited fix for this release is a solution to the rake db:create/db:drop issue. The main change is a new 'jdbc' rails generator that should be run once to prepare a Rails application to use JDBC. The upside of this generator is that you no longer will need to alter database.yml for JDBC. See the README.txt for details.

Authoritative repository now hosted at git://github.com/nicksieger/activerecord-jdbc-adapter.git; rubyforge svn trunk cleaned out.

0.8.2

Added an optional config key called :dialect. Using :dialect allows you to override the default SQL dialect for the driver class being used. There are a few cases for this:
- Using using Sybase w/ the jTDS driver.
- Using rebranded drivers.
- It makes more sense to use :dialect, rather then :driver when using JNDI.
JRUBY-2619: Typo with :test config causing problems with dev database (Igor Minar)
20524, JRUBY-2612: Since when did I think that there was a #true? method on Object?

0.8

NOTE: This release is only compatible with JRuby 1.1RC3 or later.
Because of recent API changes in trunk in preparation for JRuby 1.1, this release is not backward compatible with previous JRuby releases. Hence the version bump.

0.6

Gem is renamed to "activerecord-jdbc-adapter" to follow new conventions introduced in Rails 2.0 for third-party adapters. Rails 2.0 compatibility is introduced.
Add dependency on ActiveRecord >= 1.14 (from the Rails 1.1.x release)
New drivers (jdbc-XXX) and adapter (activerecord-jdbcXXX-adapter) gems available separately. See the README.txt file for details.
Plain "jdbc" driver is still available if you want to use the full driver/url way of specifying the driver.
More bugfixes to Oracle and SQLServer courtesy of Ola & ThoughtWorks

0.5

Release coincides with JRuby 1.0.1 release
It is no longer necessary to specify :driver and :url configuration parameters for the mysql, postgresql, oracle, derby, hsqldb, and h2 adapters. The previous configuration is still valid and compatible, but for new applications, this makes it possible to use the exact same database.yml configuration as Rails applications running under native Ruby.
JDBC drivers can now be dynamically loaded by Ruby code, without being on the classpath prior to launching JRuby. Simply use "require 'jdbc-driver.jar'" in JRuby code to add it to the runtime classpath.
Updates to HSQL, MS SQLServer, Postgres, Oracle and Derby adapters
