Existing systems keep the administrator's choice on upgrade. * Added support for DNS SRV and NAPTR records for SIP providers that spread traffic across several servers. **Improvements:** * The PBX no longer accumulates memory while idle: instead of growing past 350 MB per day it stays around 65 MB. * SSH setting changes (port, password login restriction) take effect immediately, without a reboot. * System setting changes apply instantly and are no longer overridden by outdated values after a service restart. * Updating from an image shows clear console output, and on single-disk systems a warning is displayed before the update starts. * Provider status is reported accurately: no more false "registration lost" records, list and 24-hour timeline colours now match, and a registered but unreachable trunk is marked yellow. * Disabling or deleting an outbound trunk now tells the operator to drop the registration, so incoming calls no longer arrive on a switched-off trunk. * The security-update warning for a module is now shown only to systems running a version below the fixed one. **Bug Fixes:** * Updating from an image on single-disk systems no longer wipes the partition holding call recordings and data. * Incoming calls: the line number (DID) and caller number are extracted correctly from the configured rules, and calls are no longer rejected after a cold start before the provider addresses are known. * An incoming route no longer loses its provider when edited. * Call recordings: after a failed transfer to a queue the recording is kept in full, and resumed conversation audio ends up in the final file. * Employee mobile number: short internal numbers are now accepted, and a custom dial string is no longer overwritten when the number changes. * Disabled modules no longer start their background processes, and their log files are rotated correctly again. * A single faulty module no longer stops the background processes of all other modules. * Fixed a hang during dial plan reload and restored the correct order of outbound routes. * Coupon activation no longer reports a false "coupon already activated" error, and a successful system update is no longer shown as a failure. * On virtual servers, serial port detection no longer freezes the system: hundreds of stuck processes and the blank welcome screen are gone. * Module logos and screenshots are shown again in the module marketplace, and the menu group dropdown in module settings works again. * Restored DTMF tone transmission on legacy H.323 gateways. **Security:** * The per-employee "do not record calls" setting works again: previously such conversations were recorded despite the setting. * Login with a hardware security key (YubiKey and similar) now works; keys registered earlier must be registered again. * Users with restricted permissions can set employee passwords again — strong passwords are no longer rejected as weak. * Firewall: an address blocked only for the management connection no longer blocks phone registration; enabling or disabling protection, as well as edits to the allowed and blocked address lists for web access, apply without a reboot. * Hardened protection against forged data in incoming calls and against malicious content inside installed module archives. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.mikopbx.com/mikopbx/english/other/changelog/mikopbx-2026.3.40.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
