Are Marketplace apps part of this extension program (and does that mean we can expect further revenue, and provide support, beyond the EoL date?)
All the reasons above are perfectly valid, but again as a business we need to consider the cost of continuing to invest in the platform against a decreasing revenue stream.
Again I’ll point to the Confluence 9 → 10 transition that forced incompatible pom.xml changes, resulting in us now maintaining and building two versions for every release, one for 8.x-9.x, and one for 10.x.
If what you’re saying is that these build configuration changes are fully backwards compatible with our current 10.x pom.xml file then yes, that’s a simple one-time change.
If not, and we have to maintain a third pom.xml configuration for 11.x, then we simply won’t.
We’ll happily forgo any further DC revenue between now and March 2029 and focus all of our engineering resources entirely on our Forge versions.
