Breaking Changes Between Releases

The standalone WebAPI service (nxapisrv) is deprecated and removed; the REST API is now provided by the webapi server module loaded into the server process.

The "internal" object tool type was removed and type 0 is now reserved. The built-in Wakeup node tool is converted to a server script tool (Tools::WakeUpNode) during upgrade.

A network mask is no longer accepted when creating nodes. Pseudo-interfaces created for unmanaged nodes get a synthetic mask automatically.

The Microsoft Teams notification channel driver was reworked to use Power Automate Workflows webhooks. Legacy Office 365 connectors are no longer supported, and the UseMessageCards and ThemeColor driver options are ignored.

The web management client requires a servlet container supporting Jakarta Servlet API 6.0 (Tomcat 11 or later, Jetty 12 or later).

DCIs with Script origin and DCI instance discovery scripts no longer run in the read-only security context introduced in 6.2. They can modify objects, post events, and send notifications regardless of the Scripts.RestrictWriteAccess setting. Such scripts live in the script library, and write access to the script library already allows unrestricted code to run, for example through hook scripts. All other scripts listed in Write Access Restrictions remain restricted.

%(nl) — insert new line character

%(cr) — insert carriage return character

%(lf) — insert line feed character

%(tab) — insert tab character

%(in:name) — insert input field value

The CreateDCI NXSL method changed: the last two parameters (polling interval and retention time) should be set to null instead of 0 to use default values

NXSL decimal numbers written with leading zeros are no longer interpreted as octal

Incompatible change in NXSL DCI class: instance attribute now refers to the instance value (as in {instance} macro), not instance name. Use instanceName to access the instance name.

Several Web API endpoints were renamed (e.g., API_HOME/summaryTable/adHoc became API_HOME/summary-table/ad-hoc)

Introduced boolean type in NXSL. Comparisons like func() == 1, where func returns a boolean, will always evaluate to false because the boolean value true is not equal to integer 1. This may require fixes in NXSL scripts.

Regexp matching operation in NXSL now returns an array with capture groups or false as a result.

Clusters now have configuration poll. If you have a configuration poll hook script that references $node, this will produce errors when configuration poll runs on a cluster. Replace $node with $object or add a guard: if (classof($object) == "Node").

Regexp matching operation in NXSL returns array with capture groups or NULL as result

NXSL objects and arrays in logical expressions are evaluated to TRUE — this may require NXSL script adjustments

Notification channels introduced as new functionality. SMS configuration is automatically migrated from server configuration to a notification channel based on the old driver name (AnySMS, DBTable, Dummy, GSM, Kannel, MyMobile, Nexmo, NXAgent, Portech, Slack, SMSEagle, Text2Reach, WebSMS). No manual action required.

Flags and dynamic flags moved to the NetObject class. Node flags are separated into user-set flags and system-set capability flags. Numeric values for flags, capabilities, and dynamic flags were changed — this affects NXSL scripts that check those flags directly.

The 32-bit version of the management client is no longer available.

The agent always requires encryption unless the RequireEncryption parameter is explicitly set to off. You may need to add this parameter where encryption is not desired.

Agent policies were merged with templates. Each policy was converted to a template. No manual changes required.
