What is the supported version of SPFX for SPSE?

TroyStarr I am really surprised that anyone needs to be asked why they would want to use a newer version of SPFx. The question should be why not? Cloud dependencies and whatnot is not a valid excuse. Many organisations will continue to use on prem option for the foreseeable future and are being severely handicapped when it comes to development. I am a developer in one such organisation and am constantly disappointed by how poorly thought out SP19 was and am even more disappointed that a product you are releasing 3 years later uses exactly the same SPFx version. From a developer perspective SP SE is basically SP19 on subscription. I think any developer worth their salt can be trusted to work out what they can and can't do with the newer versions on SPFx within an on prem environment, so give us the flexibility please!

Hello TroyStarranother obvious reason that haven't been listed yet are the obvious security risks. Many of the packages used by SPFx 1.4.1 use already vulnerable version that have been long patched in the new version. But we can't use them because we are locked to legacy version.Here is the result of the XRay alert in our pipeline when building SPFx 1.4.1[Pipeline] xrayScanSecurity Violations# Severity Component CVE1 High handlebars:4.1.2 CVE-2021-233692 High handlebars:4.1.23 High handlebars:4.1.2 CVE-2019-209224 High handlebars:4.1.2 CVE-2019-199195 High handlebars:4.1.2 CVE-2021-233836 High diff:3.2.07 High js-yaml:3.13.1 CVE-2021-221508 High js-yaml:3.7.0 CVE-2021-221509 High lodash:2.4.2 CVE-2021-4172010 High handlebars:4.1.211 High handlebars:4.1.212 High js-yaml:3.7.013 High lodash:1.0.2 CVE-2021-4172014 High acorn:5.7.315 High handlebars:4.1.2 CVE-2019-2092216 High handlebars:4.1.2 CVE-2021-2336917 High handlebars:4.1.218 High handlebars:4.1.219 High handlebars:4.1.2 CVE-2019-1991920 High handlebars:4.1.221 High acorn:5.7.322 High js-yaml:3.13.1 CVE-2021-2215023 High handlebars:4.1.224 High diff:3.2.025 High js-yaml:3.7.026 High lodash:1.0.2 CVE-2021-4172027 High js-yaml:3.7.0 CVE-2021-2215028 High tmpl:1.0.4 CVE-2021-377729 High handlebars:4.1.2 CVE-2021-2338330 High handlebars:4.1.231 High lodash:2.4.2 CVE-2021-41720And as developer I totally hate being locked to the old versions of TS, React. Node etc.Also some industries have so tight legislative regulations (Swiss banking in my current case) that going to cloud is more difficult on the legal than technical level. So staying on SP2019 will be a security risk now.

That is very disappointing. The last sentence doesn't give much hope either..

TroyStarr 1) Tenant wide extensions deployment. We have to do powershell workaround for that or manually upload/uninstall it everywhere.2) React, Fluent UI, TS versions bump. There are workarounds (https://spblog.net/post/2019/08/08/build-sharepoint-framework-solutions-for-on-premises-sharepoint-with-any-version-of-react-typescript-or-office-ui-fabric-react) but it makes solution unnecessarily complicated. PnPjs is popular lib and currently we have to do workaround to install it https://pnp.github.io/pnpjs/SPFx-on-premises/. I don't expect latest and greatest versions, I understand that onprem is always behind.

Hi Vinicius Fortes, the RTM/GA release of SharePoint Server Subscription Edition continues to support SharePoint Framework version 1.4.1. Note that the new continuous update model we've adopted for SharePoint Server Subscription Edition gives us the ability to release new feature innovation even after GA, so the SharePoint Framework version we support may change in the future.

    Hi Int_A1730, what capabilities in the newer SharePoint Framework versions are you interested in and why do you think they would be important to add to SharePoint Server Subscription Edition? I ask because we have many good ideas for additional improvements we could make to SharePoint Server Subscription Edition from customers, so hearing specifically what you're interested in and why will help us as we prioritize what we focus on.

  Hi Nicolae, SharePoint Framework support was updated to version 1.5.1 in the Version 23H1 feature update for SharePoint Server Subscription Edition. As documented on our SharePoint Framework development with SharePoint Server 2019 and Subscription Edition page, we also support Node.js versions up to version 14.
  
  This is one step on our long-term journey to improve and expand the capabilities of SharePoint Framework in SharePoint Server Subscription Edition. We'll continue investing in supporting newer SharePoint Framework capabilities and related technologies, such as newer versions of Node.js, React, etc. Support for these related technologies will be decoupled from the SharePoint Framework version we declare support for, so we'll be able to support newer versions of those technologies even if the original release of any particular SharePoint Framework version didn't support it. The next feature update for SPSE will focus on supporting newer versions of React and Office UI Fabric React.

    TroyStarrSo you are telling me, that after years we were able to receive version 1.5.1 which is from year 2018?
    How much longer till we get at least 1.10.0 which is still from 2020?
