===
=== These files document all the changes that MUST be taken

=== 'deprecated' and may be removed in a future release,
=== along with the suggested replacement functionality.

===========================================================
New in 16.0.0:
app_fax:
- The app_fax module is now deprecated, users should migrate to the
replacement module res_fax.
app_macro:
- The app_macro module is now deprecated and by default it is no longer
built. Users should migrate to app_stack (Gosub). A warning is logged
the first time any Macro is used.
AMI:
- The ContactStatus and Status fields for the manager events ContactStatus
and ContactStatusDetail are now set to "NonQualified" when a contact exists
but has not been qualified.
- The ContactStatus event will no longer be sent by PJSIP when a device
refreshes its registration.
- The "Newexten" event is now part of the "dialplan" class. The documentation
for Asterisk 15 already specified this, but the implementation was actually
using the "call" class instead.
ARI:
- The ContactInfo event's contact_status field is now set to "NonQualified"
when a contact exists but has not been qualified.
Build System:
- MALLOC_DEBUG no longer has an effect on Asterisk's ABI. Asterisk built
with MALLOC_DEBUG can now successfully load binary modules built without
MALLOC_DEBUG and vice versa. Third-party pre-compiled modules no longer
need to have a special build with it enabled.
- Asterisk now depends on libjansson >= 2.11. If this version is not
available on your distro you can use `./configure --with-jansson-bundled`.
chan_dahdi:
- Timeouts for reading digits from analog phones are now configurable in
chan_dahdi.conf: firstdigit_timeout, interdigit_timeout, matchdigit_timeout.
cdr_syslog:
- The cdr_syslog module is now deprecated and by default it is no longer
built.
res_config_sqlite:
- The res_config_sqlite module is now deprecated, users should migrate to the
replacement module res_config_sqlite3.
res_monitor:
- The res_monitor module is now deprecated, users should migrate to the
replacement module app_mixmonitor.
Core:
- libedit is no longer available as an embedded library and must be provided
by the system.
- The module loader now enforces inter-module dependencies. This ensures that
a module is not started before another it depends on, even if preload is used.
If a dependency is not available or fails to startup this will block any
dependants from startup.
- Parts of the Asterisk core which can load configuration from realtime are now
built-in modules. It is no longer necessary to preload realtime drivers as
they are always initialized before the built-in modules.
