0.19.0

Features:

• Global search on organizations, applications, devices and gateways.
• Display live device events (the same data as publised over MQTT).
  See also Event logging.

Improvements:

• When creating an application, show a warning when no service-profile exists.
• When creating a gateway, show a warning when no network-server has been associated.
• When creating a device, show a warning when no device-profile exists.

Bugfixes:

• Fix organization selector (which would sometimes show an empty value on select).
• Fix user selector when assigning an user to an organization (which would sometimes show an empty value on select).

Upgrade notes:

Before upgrading, the PostgreSQL pg_trgm extension needs to be enabled.
Assuming the LoRa App Server database is configured as loraserver_as this
extension could be enabled using the commands below.

Start the PostgreSQL prompt as the postgres user:

sudo -u postgres psql

Within the PostgreSQL prompt, enter the following queries:

-- change to the LoRa App Server database
\c loraserver_as

-- enable the extension
create extension pg_trgm;

-- exit the prompt
