  19. ===========================================================
  20. From 1.8.13 to 1.8.14:
  21. * permitdirectmedia/denydirectmedia now controls whether peers can be
  22. bridged via directmedia by comparing the ACL to the bridging peer's
  23. address rather than its own address.
  24. From 1.8.12 to 1.8.13:
  25. * The complex processor detection and optimization has been removed from
  26. the makefile in favor of using native optimization suppport when available.
  27. BUILD_NATIVE can be disabled via menuselect under "Compiler Flags".
  28. From 1.8.10 to 1.8.11:
  29. * If no transport is specified in sip.conf, transport will default to UDP.
  30. Also, if multiple transport= lines are used, only the last will be used.
  31. From 1.6.2 to 1.8:
  32. * chan_sip no longer sets HASH(SIP_CAUSE,<chan name>) on channels by default.
  33. This must now be enabled by setting 'sipstorecause' to 'yes' in sip.conf.
  34. This carries a performance penalty.
  35. * Asterisk now requires libpri 1.4.11+ for PRI support.
  36. * A couple of CLI commands in res_ais were changed back to their original form:
  37. "ais show clm members" --> "ais clm show members"
  38. "ais show evt event channels" --> "ais evt show event channels"
  39. * The default value for 'autofill' and 'shared_lastcall' in queues.conf has
  40. been changed to 'yes'.
  41. * The default value for the alwaysauthreject option in sip.conf has been changed
  42. from "no" to "yes".
  43. * The behavior of the 'parkedcallstimeout' has changed slightly. The formulation
  44. of the extension name that a timed out parked call is delivered to when this
  45. option is set to 'no' was modified such that instead of converting '/' to '0',
  46. the '/' is converted to an underscore '_'. See the updated documentation in
  47. features.conf.sample for more information on the behavior of the
  48. 'parkedcallstimeout' option.
  49. * Asterisk-addons no longer exists as an independent package. Those modules
  50. now live in the addons directory of the main Asterisk source tree. They
  51. are not enabled by default. For more information about why modules live in
  52. addons, see README-addons.txt.
  53. * The rarely used 'event_log' and LOG_EVENT channel have been removed; the few
  54. users of this channel in the tree have been converted to LOG_NOTICE or removed
  55. (in cases where the same message was already generated to another channel).
  56. * The usage of RTP inside of Asterisk has now become modularized. This means
  57. the Asterisk RTP stack now exists as a loadable module, res_rtp_asterisk.
  58. If you are not using autoload=yes in modules.conf you will need to ensure
  59. it is set to load. If not, then any module which uses RTP (such as chan_sip)
  60. will not be able to send or receive calls.
  61. * The app_dahdiscan.c file has been removed, but the dialplan app DAHDIScan still
  62. remains. It now exists within app_chanspy.c and retains the exact same
  63. functionality as before.
  64. * The default behavior for Set, AGI, and pbx_realtime has been changed to implement
  65. 1.6 behavior by default, if there is no [compat] section in asterisk.conf. In
  66. prior versions, the behavior defaulted to 1.4 behavior, to assist in upgrades.
  67. Specifically, that means that pbx_realtime and res_agi expect you to use commas
  68. to separate arguments in applications, and Set only takes a single pair of
  69. a variable name/value. The old 1.4 behavior may still be obtained by setting
  70. app_set, pbx_realtime, and res_agi each to 1.4 in the [compat] section of
  71. asterisk.conf.
  72. * The PRI channels in chan_dahdi can no longer change the channel name if a
  73. different B channel is selected during call negotiation. To prevent using
  74. the channel name to infer what B channel a call is using and to avoid name
  75. collisions, the channel name format is changed.
  76. The new channel naming for PRI channels is:
  77. DAHDI/i<span>/<number>[:<subaddress>]-<sequence-number>
  78. * Added CHANNEL(dahdi_span), CHANNEL(dahdi_channel), and CHANNEL(dahdi_type)
  79. so the dialplan can determine the B channel currently in use by the channel.
  80. Use CHANNEL(no_media_path) to determine if the channel even has a B channel.
  81. * Added AMI event DAHDIChannel to associate a DAHDI channel with an Asterisk
  82. channel so AMI applications can passively determine the B channel currently
  83. in use. Calls with "no-media" as the DAHDIChannel do not have an associated
  84. B channel. No-media calls are either on hold or call-waiting.
  85. * The ChanIsAvail application has been changed so the AVAILSTATUS variable
  86. no longer contains both the device state and cause code. The cause code
  87. is now available in the AVAILCAUSECODE variable. If existing dialplan logic
  88. is written to expect AVAILSTATUS to contain the cause code it needs to be
  89. changed to use AVAILCAUSECODE.
  90. * ExternalIVR will now send Z events for invalid or missing files, T events
  91. now include the interrupted file and bugs in argument parsing have been
  92. fixed so there may be arguments specified in incorrect ways that were
  93. working that will no longer work. Please see
  94. https://wiki.asterisk.org/wiki/display/AST/External+IVR+Interface for details.
  95. * OSP lookup application changes following variable names:
  96. OSPPEERIP to OSPINPEERIP
  97. OSPTECH to OSPOUTTECH
  98. OSPDEST to OSPDESTINATION
  99. OSPCALLING to OSPOUTCALLING
  100. OSPCALLED to OSPOUTCALLED
  101. OSPRESULTS to OSPDESTREMAILS
  102. * The Manager event 'iax2 show peers' output has been updated. It now has a
  103. similar output of 'sip show peers'.
  104. * VoiceMailMain and VMAuthenticate, if a '*' is entered in the first position
  105. of a Mailbox or Password, will, if it exists, jump to the 'a' extension in
  106. the current dialplan context.
  107. * The CALLERPRES() dialplan function is deprecated in favor of
  108. CALLERID(num-pres) and CALLERID(name-pres).
  109. * Environment variables that start with "AST_" are reserved to the system and
  110. may no longer be set from the dialplan.
  111. * When a call is redirected inside of a Dial, the app and appdata fields of the
  112. CDR will now be set to "AppDial" and "(Outgoing Line)" instead of being blank.
  113. * The CDR handling of billsec and duration field has changed. If your table
  114. definition specifies those fields as float,double or similar they will now
  115. be logged with microsecond accuracy instead of a whole integer.
  116. * chan_sip will no longer set up a local call forward when receiving a
  117. 482 Loop Detected response. The dialplan will just continue from where it
  118. left off.
  119. * The 'stunaddr' option has been removed from chan_sip. This feature did not
  120. behave as expected, had no correct use case, and was not RFC compliant. The
  121. removal of this feature will hopefully be followed by a correct RFC compliant
  122. STUN implementation in chan_sip in the future.
  123. * The default value for the pedantic option in sip.conf has been changed
  124. from "no" to "yes".
  125. * The ConnectedLineNum and ConnectedLineName headers were added to many AMI
  126. events/responses if the CallerIDNum/CallerIDName headers were also present.
  127. The addition of connected line support changes the behavior of the channel
  128. caller ID somewhat. The channel caller ID value no longer time shares with
  129. the connected line ID on outgoing call legs. The timing of some AMI
  130. events/responses output the connected line ID as caller ID. These party ID's
  131. are now separate.
  132. * The Dial application d and H options do not automatically answer the call
  133. anymore. It broke DTMF attended transfers. Since many SIP and ISDN phones
  134. cannot send DTMF before a call is connected, you need to answer the call
  135. leg to those phones before using Dial with these options for them to have
  136. any effect before the dialed party answers.
  137. * The outgoing directory (where .call files are read) now uses inotify to
  138. detect file changes instead of polling the directory on a regular basis.
  139. If your outgoing folder is on a NFS mount or another network file system,
  140. changes to the files will not be detected. You can revert to polling the
  141. directory by specifying --without-inotify to configure before compiling.
  142. * The 'sipusers' realtime table has been removed completely. Use the 'sippeers'
  143. table with type 'user' for user type objects.
  144. * The sip.conf allowoverlap option now accepts 'dtmf' as a value. If you
  145. are using the early media DTMF overlap dialing method you now need to set
  146. allowoverlap=dtmf.
  147. From 1.6.1 to 1.6.2:
  148. * SIP no longer sends the 183 progress message for early media by
  149. default. Applications requiring early media should use the
  150. progress() dialplan app to generate the progress message.
  151. * The firmware for the IAXy has been removed from Asterisk. It can be
  152. downloaded from http://downloads.digium.com/pub/iaxy/. To have Asterisk
  153. install the firmware into its proper location, place the firmware in the
  154. contrib/firmware/iax/ directory in the Asterisk source tree before running
  155. "make install".
  156. * T.38 FAX error correction mode can no longer be configured in udptl.conf;
  157. instead, it is configured on a per-peer (or global) basis in sip.conf, with
  158. the same default as was present in udptl.conf.sample.
  159. * T.38 FAX maximum datagram size can no longer be configured in updtl.conf;
  160. instead, it is either supplied by the application servicing the T.38 channel
  161. (for a FAX send or receive) or calculated from the bridged endpoint's
  162. maximum datagram size (for a T.38 FAX passthrough call). In addition, sip.conf
  163. allows for overriding the value supplied by a remote endpoint, which is useful
  164. when T.38 connections are made to gateways that supply incorrectly-calculated
  165. maximum datagram sizes.
  166. * There have been some changes to the IAX2 protocol to address the security
  167. concerns documented in the security advisory AST-2009-006. Please see the
  168. IAX2 security document, doc/IAX2-security.pdf, for information regarding
  169. backwards compatibility with versions of Asterisk that do not contain these
  170. changes to IAX2.
  171. * The 'canreinvite' option support by the SIP, MGCP and Skinny channel drivers
  172. has been renamed to 'directmedia', to better reflect what it actually does.
  173. In the case of SIP, there are still re-INVITEs issued for T.38 negotiation,
  174. starting and stopping music-on-hold, and other reasons, and the 'canreinvite'
  175. option never had any effect on these cases, it only affected the re-INVITEs
  176. used for direct media path setup. For MGCP and Skinny, the option was poorly
  177. named because those protocols don't even use INVITE messages at all. For
  178. backwards compatibility, the old option is still supported in both normal
  179. and Realtime configuration files, but all of the sample configuration files,
  180. Realtime/LDAP schemas, and other documentation refer to it using the new name.
  181. * The default console now will use colors according to the default background
  182. color, instead of forcing the background color to black. If you are using a
  183. light colored background for your console, you may wish to use the option
  184. flag '-W' to present better color choices for the various messages. However,
  185. if you'd prefer the old method of forcing colors to white text on a black
  186. background, the compatibility option -B is provided for this purpose.
  187. * SendImage() no longer hangs up the channel on transmission error or on
  188. any other error; in those cases, a FAILURE status is stored in
  189. SENDIMAGESTATUS and dialplan execution continues. The possible
  190. return values stored in SENDIMAGESTATUS are: SUCCESS, FAILURE, and
  191. UNSUPPORTED. ('OK' has been replaced with 'SUCCESS', and 'NOSUPPORT'
  192. has been replaced with 'UNSUPPORTED'). This change makes the
  193. SendImage application more consistent with other applications.
  194. * skinny.conf now has separate sections for lines and devices.
  195. Please have a look at configs/skinny.conf.sample and update
  196. your skinny.conf.
  197. * Queue names previously were treated in a case-sensitive manner,
  198. meaning that queues with names like "sales" and "sALeS" would be
  199. seen as unique queues. The parsing logic has changed to use
  200. case-insensitive comparisons now when originally hashing based on
  201. queue names, meaning that now the two queues mentioned as examples
  202. earlier will be seen as having the same name.
  203. * The SPRINTF() dialplan function has been moved into its own module,
  204. func_sprintf, and is no longer included in func_strings. If you use this
  205. function and do not use 'autoload=yes' in modules.conf, you will need
  206. to explicitly load func_sprintf for it to be available.
  207. * The res_indications module has been removed. Its functionality was important
  208. enough that most of it has been moved into the Asterisk core.
  209. Two applications previously provided by res_indications, PlayTones and
  210. StopPlayTones, have been moved into a new module, app_playtones.
  211. * Support for Taiwanese was incorrectly supported with the "tw" language code.
  212. In reality, the "tw" language code is reserved for the Twi language, native
  213. to Ghana. If you were previously using the "tw" language code, you should
  214. switch to using either "zh" (for Mandarin Chinese) or "zh_TW" for Taiwan
  215. specific localizations. Additionally, "mx" should be changed to "es_MX",
  216. Georgian was incorrectly specified as "ge" but should be "ka", and Czech is
  217. "cs", not "cz".
  218. * DAHDISendCallreroutingFacility() parameters are now comma-separated,
  219. instead of the old pipe.
  220. * res_jabber: autoprune has been disabled by default, to avoid misconfiguration
  221. that would end up being interpreted as a bug once Asterisk started removing
  222. the contacts from a user list.
  223. * The cdr.conf file must exist and be configured correctly in order for CDR
  224. records to be written.
  225. * cdr_pgsql now assumes the encoding of strings it is handed are in LATIN9,
  226. which should cover most uses of the extended ASCII set. If your strings
  227. use a different encoding in Asterisk, the "encoding" parameter may be set
  228. to specify the correct character set.
  229. From 1.6.0.1 to 1.6.1:
  230. * The ast_agi_register_multiple() and ast_agi_unregister_multiple()
  231. API calls were added in 1.6.0, so that modules that provide multiple
  232. AGI commands could register/unregister them all with a single
  233. step. However, these API calls were not implemented properly, and did
  234. not allow the caller to know whether registration or unregistration
  235. succeeded or failed. They have been redefined to now return success
  236. or failure, but this means any code using these functions will need
  237. be recompiled after upgrading to a version of Asterisk containing
  238. these changes. In addition, the source code using these functions
  239. should be reviewed to ensure it can properly react to failure
  240. of registration or unregistration of its API commands.
  241. * The ast_agi_fdprintf() API call has been renamed to ast_agi_send()
  242. to better match what it really does, and the argument order has been
  243. changed to be consistent with other API calls that perform similar
  244. operations.
  245. From 1.6.0.x to 1.6.1:
  246. * In previous versions of Asterisk, due to the way objects were arranged in
  247. memory by chan_sip, the order of entries in sip.conf could be adjusted to
  248. control the behavior of matching against peers and users. The way objects
  249. are managed has been significantly changed for reasons involving performance
  250. and stability. A side effect of these changes is that the order of entries
  251. in sip.conf can no longer be relied upon to control behavior.
  252. * The following core commands dealing with dialplan have been deprecated: 'core
  253. show globals', 'core set global' and 'core set chanvar'. Use the equivalent
  254. 'dialplan show globals', 'dialplan set global' and 'dialplan set chanvar'
  255. instead.
  256. * In the dialplan expression parser, the logical value of spaces
  257. immediately preceding a standalone 0 previously evaluated to
  258. true. It now evaluates to false. This has confused a good many
  259. people in the past (typically because they failed to realize the
  260. space had any significance). Since this violates the Principle of
  261. Least Surprise, it has been changed.
  262. * While app_directory has always relied on having a voicemail.conf or users.conf file
  263. correctly set up, it now is dependent on app_voicemail being compiled as well.
  264. * SIP: All of the functionality in SIPCHANINFO() has been implemented in CHANNEL(),
  265. and you should start using that function instead for retrieving information about
  266. the channel in a technology-agnostic way.
  267. * If you have any third party modules which use a config file variable whose
  268. name ends in a '+', please note that the append capability added to this
  269. version may now conflict with that variable naming scheme. An easy
  270. workaround is to ensure that a space occurs between the '+' and the '=',
  271. to differentiate your variable from the append operator. This potential
  272. conflict is unlikely, but is documented here to be thorough.
  273. * The "Join" event from app_queue now uses the CallerIDNum header instead of
  274. the CallerID header to indicate the CallerID number.
  275. * If you use ODBC storage for voicemail, there is a new field called "flag"
  276. which should be a char(8) or larger. This field specifies whether or not a
  277. message has been designated to be "Urgent", "PRIORITY", or not.
