Timezone support was added to the core. All dates are now stored in UTC. Resources with old dates are converted when read, assuming the configured server timezone. You need to set the timezone in the zotonic.config file, for example:
A site-specific timezone can de set with the mod_l10n.timezone configuration.
The database driver and pool has been replaced by standard epgsql and poolboy. This removes the special Zotonic version of epgsql.
Added the notification request_context. This is a foldl with the Context and is called after the request’s query arguments are parsed using z_context:ensure_qs/1. It can be used to perform transformations or actions based on the query arguments.
