LTS Support
Community Versions

Angular is a fast paced technology with a new major version every 6 months. PrimeNG release cycle is aligned with Angular and every 6 months a new major PrimeNG version is released as open source that is compatible with the latest Angular core. The maintenance releases of the latest PrimeNG version are provided as free and open source for the following 6 months until the new major Angular version is ready.

LTS Versions

Majority of the existing applications prefer to remain at a previous version due to stability requirements instead of upgrading to the latest version immediately. PrimeNG LTS is an annual subscription based service to provide a license for the finest compatible version suited to you. LTS covers the prior two versions from the latest release, this means up to 18 months of almost bi-weekly releases to bring the latest defect fixes and security updates to your project. As an example, when PrimeNG moves to Angular 16, PrimeNG 15 and 14 will move to LTS support whereas STS (short term support) versions of PrimeNG 16 will be open source under MIT license for at least 6 months until Angular/PrimeNG 17 is released.

LTS versions require a license key and a pass key to be verified at your main app component. The keys would be available at PrimeStore under LTS Licenses section.

import { Component, OnInit } from '@angular/core';
import { LicenseManager } from 'primeng/api';

    selector: 'app-root',
    templateUrl: './app.component.html'
export class AppComponent implements OnInit {

    constructor(private licenseManager: LicenseManager) {}

    ngOnInit() {
        this.licenseManager.verify('LICENSE_KEY', 'PASS_KEY');
