When working with UI5 or running UI5 apps it is very important to update your system on a regular base. This not only relates to the aspect that outdates UI5 versions get no longer support but SAP also strongly recommends that customers apply patches on a priority to protect their SAP landscape. This is one of the reason SAP does de-provisioning outdated UI5 versions from its CDN.
As the year 2022 ends, let's have a look which UI5 versions will become outdated in 2023 so you can plan accordingly.
UI5 releases reaching the end of its support cycle in 2023:
As 1.71 is a special long-term maintenance (LTS) version, that receives not only three but eight years of support, there is no LTS versions reaching end of maintenance in 2022. (If you wonder why v1.71 gets this special treatment: This is because of the extended maintenance period of SAP Fiori FES 6.0 that includes SAPUI5 1.71.Therefore, the maintenance period for this UI5 version was also extended in general, and not only for the ABAP stack). However, there are the interim versions, which support expires once a successor version is available. End of 2023 also support for the long-term maintenance version 1.84 expires. So in case your apps are running on one of these versions it is essential to plan for an upgrade!
Here the UI5 versions reaching the end of its support cycle in 2023 at a glance:
End of Maintenance
Q1/2023 (as soon as v1.110 become available)
End of Q1/2023
End of Q4/2023
It goes without saying that this overview contains only versions which currently exist (as of December 05, 2022) since further interim versions will be published next year as usual.
UI5 releases reaching the end of cloud provisioning in 2023
As you hopefully know, outdated SAPUI5/OpenUI5 versions are removed from our CDN on a regular base. Although this was announced early and well-founded through different channels, there still seems to be people who are surprised by this fact as they don't quite understand the procedure yet.
Roughly summarized, the fact is that every UI5 version will be removed from CDN one year after it became outdated. In this context, outdated means either that a higher patch is available for a given minor version or the given minor version reached end of maintenance. Therefore, also if you run a UI5 version with long-term maintenance it is essential to check on a regular base on new patches to be aware when a specific version becomes outdated!
It is also important to understand that this situation might have also an effect on your on Premise landscape in case you run the UI5 app stored on your system on SAP Build Work Zone Standard Edition (aka cFLP). Because here the launchpad detects the UI5 version from your system but only uses the one from CDN. And if this version is not available anymore, the app cannot be displayed! So, also here it is essential to take care if the UI5 version you are using is up to date! However, if if this is not your scenario it is still very reasonable to import new patches once available.
Here the UI5 versions that will be removed from the SAPUI5 CDN during 2023 at a glance. As a UI5 version with End of Cloud Provisioning (EoCP) in Q4/22 will be only deleted beginning of 2023 that's were the table starts:
The versions highlighted in blue are patches of UI5 versions still in long-term maintenance. If you are using any of them, we recommend upgrading to the latest patch available of the respective UI5 version. Alternatively and in case your app is relying on SAPUI5, you can switch the evergreen variant for bootstrapping from the SAPUI5 CDN. Read also the blog post SAPUI5 - Patch-Level-Independent Bootstrapping for further information on the evergreen version.
Versions highlighted in red point out that with the removal of these patches the respective UI5 version will be no longer available on the UI5 CDN. You are strongly advised to plan for an upgrade to a UI5 version still in maintenance.
Please note, that the dates above show the current situation and may still be subject to change, therefore we highly recommend checking the Version Overview page for SAPUI5/OpenUI5on a regular basis!
To sum up this blog post, I would like to ask everyone to follow the UI5 maintenance strategy. Don't use versions out of maintenance and plan for regular (patch) updates to ensure that your UI5 apps run smoothly and are safe to use for your users. With this in mind, we wish you a successful 2023.
