| '''WARNING''': Starting from firmware version '''4.5.4''', there is a '''1GB RAM''' requirement for VMs. If the firmware is updated or installed on a VM that does not meet the memory requirements, the PBX will fail to start.
| '''N.B.''': The '''minimum''' RAM requirement for VMs is '''2GB'''. If the RAM is below this requirement, the PBX will not start. The '''recommended''' RAM requirement for VMs with firmware version 4.9.8 or later is '''4GB'''.

= Bootloader =
The bootloader is the base operating system of the PBX. It does not contain telephone features but is used to install and manage the firmware. The bootloader is updated similarly to the firmware, but it is updated ''in place'' and cannot be returned to return to a previous version. After a new bootloader is installed, the PBX will need to be rebooted (on the bootloader itself) to complete the procedure. After this, it will be possible to reboot the PBX normally on one of the available firmware versions.
 
== Bootloader 1.1.0 ==
 
This update adds to the bootloader software components usually distributed within the firmware, reducing the size of future updates. Bootloader version 1.1.0 is required for installing firmware updates starting from version 4.10 and 4.11

===Bugfixes===
===Bugfixes===
* GUI
** K-5821: Fixed an error where the validation of passwords according to the new policy introduced in 4.11.11 was applied, in the user panel of password change, also to the old password, which caused the need for the admin to change passwords only from the Users and Roles panel (where the old one is not required as it is a reset action).

After acquiring a dedicated license, the PBX admin will be able to assign to user groups the management of licensed video conference rooms; through the KalliopePBX web interface the user can easily view the status of each room, create a new meeting adding internal and external participants, and send invitations via email.
**0005428: Fixed a bug where every "Apply" reset the queue statistics (and therefore caused the ring strategies to malfunction)
 
**0005531: Fixed a bug that sometimes caused the incorrect visualization of older calls in the supervisor panel
N.B.: the handling of issue K-3770 changes the '''way the phonebook is accessed via LDAP'''. Up until version 4.11.2 it was possible to access the dc=extensions,dc=phonebook,dc=<domain> sub-branch,dc=root anonymously, and authentication was only necessary to access the dc=system,dc=phonebook,dc=<domain>,dc=root sub-branch. Starting from this version, access to both sub-branches '''requires authentication'''.
*GUI
**0005342: User dashboard: fixed the links to groups and queues
*Multi-tenant
**0005469: Fixed an error with multi-tenant license activation when gateways with no assigned lines were present
**0005412: Fixed an error that prevented notifications for non-default tenants from being sent


== Firmware 4.5.6 (12/12/2017) ==


===New features===
===New features===
* Event notification service. This release introduces an '''engine for managing events''', which can be generated both on a node/system level and on a single tenant level (telephone events). The first events to be introduced concern the registration of the outcome of calls in queues (pbx.queue.servedcall and pbx.queue.unservedcall events). A configuration page for the '''event notification service''' is also available; it lets users associate to each event (or event class) one or more notification actions (either sending an '''email''' or invoking a '''web service'''), which are completely configurable with the attributes of the corresponding event.
* GUI
* "Do Not Disturb" (DND) service. Adds the '''DND service on an extension level'''. The DND service implemented on a PBX level differs from the one available on telephone terminals in that it operates on the entire extension and not for the single SIP account configured on the terminal. The DND service operates on calls made '''directly to the extension''' as well as those that are presented to the extension as member of a '''ring group''' (but not for queues) and ensures that the extension is treated as "unavailable" when choosing a failover action (for direct calls). The DND state can be changed via BLF key (dnd<extension> selection), with which it is also possible to view the state of activation, or via the /rest/operation/service/dnd/<extension> REST API.
** K-2282: Added support for the KalliopeLAM video conferencing service
* REST APIs for the '''operation of extension services'''. Added /rest/operation/service/<service>/<extension> REST APIs in GET/POST and DELETE modes to read, set, and reset the state of the following extensions services: DND ('''Do Not Disturb'''), FORKMOBILE ('''Fork to Mobile'''), CFIM ('''Unconditional forward''' or call redirection). The APIs can be used with API access permissions and authentication by each user (for single extensions) and by users with a Power User role that is enabled to manage the "operating state of the services" (for all extensions).
** K-2473: Added management of closed groups and pickup groups with the option to exceed the predefined limit of 63 and with the option to assign mnemonic names instead of the identification number
* REST APIs for the dynamic management of queue operators. Added /rest/operation/queue/<operation> REST APIs to manage '''pause''' and add/remove '''dynamic operators''' to/from a queue.
 
* The "Service" and "Queue" '''widgets''' have been extended; it is now possible to '''change the state''' of the "Unconditional Forward" and "Fork to Mobile" services and change the pause status of one's SIP accounts on each queue with a handy switch.
* Kalliope-Lift module
** K-449: Added Amphitec protocol support

The KalliopePBX firmware follows a 4.X.Y numbering system where:

  • X is the Major Version:
    • releases with an even Major Version number (4.0.Y beginning from 4.0.8, 4.2.Y, etc.) are Maintenance Releases (MR), i.e. stable versions that mostly contain bugfixes; these releases add fewer features but guarantee greater stability;
    • releases with an odd Major Version number (4.1.Y, 4.3.Y, etc.) are Technology Releases (TR), i.e. versions which introduce new features;
  • Y is the Minor Version, the sequential identifier of releases within the same Major Version.


N.B.: The minimum RAM requirement for VMs is 2GB. If the RAM is below this requirement, the PBX will not start. The recommended RAM requirement for VMs with firmware version 4.9.8 or later is 4GB.

Bootloader

The bootloader is the base operating system of the PBX. It does not contain telephone features but is used to install and manage the firmware. The bootloader is updated similarly to the firmware, but it is updated in place and cannot be returned to return to a previous version. After a new bootloader is installed, the PBX will need to be rebooted (on the bootloader itself) to complete the procedure. After this, it will be possible to reboot the PBX normally on one of the available firmware versions.

Bootloader 1.1.0

This update adds to the bootloader software components usually distributed within the firmware, reducing the size of future updates. Bootloader version 1.1.0 is required for installing firmware updates starting from version 4.10 and 4.11

N.B.: There is a procedure to resolve the ERR_UNSAFE_PORT issue with Chrome and Firefox browsers. For more information on the procedure to follow (Click here)

Changes

  • System:
    • K-2630: Changed the firmware update download path to fix an issue where updates sometimes failed if the RAM assigned to the Kalliope VM was limited.

Bootloader 1.0.7

This update changes the file system of the storage partition to add a journaling feature. This change helps reduce the file corruption issues present in this file system (configurations, logs, databases) that may occur in case of a power failure when the system is writing the data.

N.B. This bootloader is a prerequisite for installing firmware equal to or later than version 4.8.0.

Changes

  • System:
    • 6694: Added journaling to file system/storage

Firmware 4.11.0 (08/06/2020)

This version introduces support for a new optional module, extended third-party SIP phone support, concerning the integrated management of phones that implement some functions though non-standard SIP variants. At the moment these include some Cisco Unified IP Phones of the 79xx series that are flashed with SIP firmware, and others that share this property (e.g. 78xx).

The module enables handling of BLF (Busy Lamp Field) keys though the assigned SIP account panel and the generation of the corresponding provisioning file for the phone. Some services can also be controlled through the phone function keys (call pickup on BLF, unconditional call forward). The LDAP phonebook can also be accessed by phones for direct consultation.

Changes

Known issues

See 4.8.0

Bugfixes

  • CDR
    • K-1153: Fixed a bug introduced in version 4.8.0 that caused outbound fax calls and calls made through the click-2-call service not to be displayed in the CDR

Firmware 4.8.2 (23/12/2019)

See 4.8.0

Bugfixes

  • Multi-tenant
    • K-994: Fixed a bug present in version 4.8.0 that caused manipulation rules for calling and called numbers on outbound lines assigned to the tenants not to be applied

Firmware 4.8.0 (2/12/2019)

WARNING: This update distributes the updated certificates required by Apple's PushKit service. The certificates installed with previous versions will expire in January 2020. To guarantee the correct functioning of the KalliopeCTI mobile app for iOS after that date, it is necessary to update KalliopePBX to this version.


N.B.: In order to update the firmware to version 4.8.0, it is necessary to update the bootloader to version 1.0.7 (which is recommended even for previous firmware versions).

Known issues

For outbound lines (gateways, trunks, or terminations) with a space in their name (e.g. "Outbound line"), the outcome of outbound calls will always be reported in the CDR as "NOANSWER" even if the call was answered and its "Conversation time" attribute is not null. The current workaround is to remove any spaces in the names of all outbound lines.

New features

  • Kalliope CTI
    • Kalliope-135: Fixed a performance issue with the queries used to pass the user CDRs to the KalliopeCTI clients that caused the data to be slow to update on the client when the PBX had a high number of calls (more than a hundred thousand per month)
  • Fax module
    • Kalliope-647: Fixed a bug that caused fax log export requests to generate an empty file
