General: Made error logging less verbose in the event of no valid lookup services. This is already reported by hook_requirements so watchdog as well is overkill.
PCAPredict: Tidied up variable checks.
PCAPredict: Added hook_requirements implementation to report a warning if the licence key is not entered

UX Tweak: Moved search again button to the top of the address form

PCAPredict: Resolved issue where the locality and dependent_locality showed duplicate values for some addresses

PCAPredict: Resolved issue where building number was being incorrectly prepended to the premise field instead of thoroughfare.
Refactored logic for populating the thoroughfare field into a helper function.

PCAPredict: Removed workaround to use 'Everything' search after a
'PostalCodes' search.

Removed validate function from the house number field.

Updated the postal code field validate function to prepend the house
number field value to the search term if present. This results in more
accurate results and better performance.

Tweaked error messaging on a lookup with zero results.

Resolved issue where the full address form could sometimes be hidden even when validation errors are present on those fields

PCAPredict: Added fallback to use ProvinceName field from an address retrieve is the Province field is empty

PCAPredict: Resolved issue where the administrative area field would not be populated when selecting an address on an international or multi-step lookup

PCAPredict: Resolved issue where some multi-step lookups could fail if an interim resultdoes not contain an explicit postcode value

PCAPredict: Improved logic for setting address details; fallback to Line1, Line2 if Street/SecondaryStreet are not populated.
PCAPredict: Added extra API call if the first one returns 0 results. Second call sets filter to 'Everything'

Added update hook to migrate postcode anywhere config variables. Variable names have changed since the last release

Updated the country data checking logic to use the new variable instead of a hardcoded default

Added a new test for the node edit form; to ensure only the 'search again' button is present in the address field.

Resolved issues in Admin UI test where just the existence of fields was being tested; not their values too.

Added new test class for testing the field API interaction.

Added new function to the test base class for setting up a new address field instance with the lookup handler enabled

from the default service module instead of an open alter.

Removed hacky cache bypass on the get addresses logic.

Added new alter hook to allow other modules to alter the cache ID.

Refactored implementation of lastId parameter to get/set on the service
object before passing through to the API adapter.

Resolved issue where lookup form would display for already populated address fields (e.g. an existing node).

Updated the lookup function of the pca predirect service to append the next operation to the ID. Colon separated.

Added some enum values to the PCA Predict abstract class for indicating 'Next' operations.

Upated the retrieve function of the API adapter to split the ID value on a colon to get the actual ID and 'Next' operation.

Refactored multi-step lookup logic to support result sets with a mix of 'Find' and 'Next' operations.

Added custom AJAX callback for the address select drop down for use in PCA Predict multi-step lookups.

Added no cache flag to the get addresses function. A temporary measure, needs re-thinking before release.

Improved address field plugin performance by not invoking format updates outside of form mode.

Updated pca predict lookup function to append the 'Description' value from the API for each result if present.

First working version of multi-step lookup. A few TODOs for next time ;)

Updated the PCAPredict API adapater to use the country value in the find function.

Updated the addressfield_lookup_get_addresses to append the country code to the cache ID if present.

Updated postcodeanywhere factory function to instantiate the wrapper object and pass to the lookup service.

Updated the address field handler to only add lookup functionality if a postcode field is available.

Refactored AddressFieldLookupPostcodeAnywhere functions to respect API response changes.

Updated the address selection drop down options to make place optional.

Added unit test for hook_requirements message

Updated API.txt

Removed directory factory function calls from addressfield_lookup_get_addresses and addressfield_lookup_get_address_details
