TAO Testing
TAO opens the 56.15 line with a database index while patching a bad migration on three branches.
A side-by-side editorial comparison of IXL and Open edX — release velocity, themes, recent moves, and the top alternatives to consider.
IXL is turning its diagnostic from a testing window into an on-demand check.
IXL's feed alternates between monthly "What's new" digests and announcements for the LevelUp Diagnostic, which is clearly the centre of current work. Over the summer LevelUp gained national K-12 norms for math and ELA, a faster ELA form, and now a Snapshot variant positioned as a just-in-time progress check. Curriculum expansion continues alongside, most visibly PreK-2 Spanish language literacy. Feed bodies are truncated teasers, so scope has to be read from titles and framing.
Open edX is rebuilding course authoring around reusable Libraries.
The Ulmo release in January 2026 lets authors build complete course structures inside Libraries and sync them into multiple courses with visual diff before apply. That extends the Teak (mid-2025) Libraries work and the Sumac (Feb 2025) Content Libraries beta. Content Tagging (March 2025) sits underneath as the indexing layer making reuse navigable.

IXL is building LevelUp into the measurement layer districts already buy elsewhere. Norming it nationally makes its scores comparable to dedicated benchmark assessments; shortening the ELA form and adding an on-demand Snapshot attacks the other constraint, which is that benchmark testing happens on a fixed calendar. Practice content and assessment are being knitted into one purchase rather than sold as separate products.
Expect Snapshot results to be wired back into IXL's recommendations and reporting, so a mid-cycle check feeds the practice assignments rather than just producing a score.

Open edX has spent the last four named releases — Sumac, Teak, Ulmo, with Content Tagging in between — turning Libraries into the first-class authoring primitive instead of treating each course as a silo. The product is moving from one-course-at-a-time authoring toward a content-reuse model that resembles how textbook publishers and large training orgs actually want to work.
The next release will likely close more of the Libraries-to-course gap: branching/versioning of library content, finer-grained sync controls, and probably AI-assisted authoring on top of the tagged-and-libraried content base.
