This is an overview of the user-visible changes to Catalyst between major Catalyst releases.
+=head2 VERSION 5.90053
+
+We are now clarifying the behavior of log, plugins and configuration during
+the setup phase. Since Plugins might require a log during setup, setup_log
+must run BEFORE setup_plugins. This has the unfortunate side effect that
+anyone using the popular ConfigLoader plugin will not be able to supply
+configuration to custom logs since the configuration is not yet finalized
+when setup_log is run (when using ConfigLoader, which is a plugin and is
+not loaded until later.)
+
+As a workaround, you can supply custom log configuration directly into
+the configuration:
+
+ package MyApp;
+ use Catalyst;
+
+ __PACKAGE__->config(
+ my_custom_log_info => { %custom_args },
+ );
+
+ __PACKAGE__->setup;
+
+If you wish to configure the custom logger differently based on ENV, you can
+try:
+
+ package MyApp;
+
+ use Catalyst;
+ use Catalyst::Utils;
+
+ __PACKAGE__->config(
+ Catalyst::Utils::merge_hashes(
+ +{ my_custom_log_info => { %base_custom_args } },
+ +{ do __PACKAGE__->path_to( $ENV{WHICH_CONF}."_conf.pl") },
+ ),
+ );
+
+ __PACKAGE__->setup;
+
+Or create a standalone Configuration class that does the right thing.
+
+Basically if you want to configure a logger via Catalyst global configuration
+you can't use ConfigLoader because it will always be loaded too late to be of
+any use. Patches and workaround options welcomed!
