+------------------------------------------------------------------------------
+--- Functionality changes from Asterisk 16.27.0 to Asterisk 16.28.0 ----------
+------------------------------------------------------------------------------
+
+chan_dahdi
+------------------
+ * A POLARITY function is now available that allows
+ getting or setting the polarity on a channel
+ from the dialplan.
+
+db
+------------------
+ * The DBPrefixGet AMI action now allows retrieving
+ all of the DB keys beginning with a particular
+ prefix.
+
+res_cliexec
+------------------
+ * A new CLI command, dialplan exec application, has
+ been added which allows dialplan applications to be
+ executed at the CLI, useful for some quick testing
+ without needing to write dialplan.
+
+res_geolocation
+------------------
+ * * Added processing for the 'confidence' element.
+ * Added documentation to some APIs.
+ * removed a lot of complex code related to the very-off-nominal
+ case of needing to process multiple location info sources.
+ * Create a new 'ast_geoloc_eprofile_to_pidf' API that just takes
+ one eprofile instead of a datastore of multiples.
+ * Plugged a huge leak in XML processing that arose from
+ insufficient documentation by the libxml/libxslt authors.
+ * Refactored stylesheets to be more efficient.
+ * Renamed 'profile_action' to 'profile_precedence' to better
+ reflect it's purpose.
+ * Added the config option for 'allow_routing_use' which
+ sets the value of the 'Geolocation-Routing' header.
+ * Removed the GeolocProfileCreate and GeolocProfileDelete
+ dialplan apps.
+ * Changed the GEOLOC_PROFILE dialplan function as follows:
+ * Removed the 'profile' argument.
+ * Automatically create a profile if it doesn't exist.
+ * Delete a profile if 'inheritable' is set to no.
+ * Fixed various bugs and leaks
+ * Updated Asterisk WiKi documentation.
+
+res_pjsip
+------------------
+ * A new transport option 'allow_wildcard_certs' has been added that when it
+ and 'verify_server' are both set to 'yes', enables verification against
+ wildcards, i.e. '*.' in certs for common, and subject alt names of type DNS
+ for TLS transport types. Names must start with the wildcard. Partial wildcards,
+ e.g. 'f*.example.com' and 'foo.*.com' are not allowed. As well, names only
+ match against a single level meaning '*.example.com' matches 'foo.example.com',
+ but not 'foo.bar.example.com'.
+
+res_pjsip_header_funcs
+------------------
+ * Add function PJSIP_RESPONSE_HEADERS() to get list of header names from 200 response, in the same way as PJSIP_HEADERS() from the request.
+
+ Add function PJSIP_RESPONSE_HEADER() to read header from 200 response, in the same way as PJSIP_HEADER() from the request.
