Iris ships steadily on a two-a-year cadence, but its feed publishes only pointers.

earth sciencerelease cadencepythonrelease candidatesthin release notes
◆Current state
Iris tags a release candidate roughly every four to five months — 3.13 through 3.16 over the past year — and the cadence is the only thing the feed actually reports. Every entry is the same seven-line template: a line saying this is a release candidate, conda-forge and PyPI install commands, and a link to a 'What's New' page held elsewhere. No release notes reach the feed at all.
◆Where it's heading
The version numbers say a mature Met Office library is being maintained on a predictable schedule; nothing in the published entries says what is being maintained. Until the project puts release content in the tag body, its public trail will read as cadence without substance, and readers have to leave the feed to learn anything. The pattern has been identical across four consecutive releases, so it is a deliberate publishing choice rather than an oversight.
◆Prediction
Expect v3.17.0rc0 around late 2026 on the same schedule, carrying the same boilerplate — the notes will again live on the documentation site rather than in the release entry.

◆Recent moves

    v3.16.0rc0

    A release candidate announcement carrying install commands and a link to the What's New page, with no notes in the entry itself. It confirms the 3.16 cycle opened on schedule but says nothing about what changed.

    v3.15.0rc0

    The 3.15 release candidate, published with the identical template — install lines and a pointer offsite. Another data point in the four-a-row pattern of content-free release entries.

    v3.14.0rc0

    The 3.14 release candidate, again boilerplate only. Reading the cadence is possible; reading the release is not.

    v3.13.0rc0

    The 3.13 release candidate and the earliest of the four identical stubs, establishing the template the project has used unchanged since.
