Beta 2 landed on February 26th and Beta 3 is due March 5th. The parts that matter for developers: blocks you can register in PHP alone, an iframed editor that isolates your CSS, and the handbook back in sync with Gutenberg 22.6.
A nightly job spent 129 seconds labelling 500,000 rows of sales data because it looped over them. The same logic with numpy.where took 0.08 seconds. Here is how vectorization and Boolean masks replace row-by-row Pandas code, and when apply() is still worth reaching for.
WordPress 7.0 reworks DataViews and DataForm. The Field API gains a format property and adaptiveSelect, DataForm gets a native details layout with built-in validation, and groupByField becomes a groupBy object that breaks 6.9 view configs without warning.

Bookmarklets still solve small browser problems faster than installing an extension. How to wrap one in an IIFE, why you should URL-encode it, editing the CSSOM instead of injecting a style tag, and what Content Security Policy does to all of it.
Nested loops don’t scale for scheduling and resource allocation. This post shows how graph coloring, using Python’s GCol library and NetworkX, solves these NP-hard problems without turning your backend logic into a mess.
Popover API and Dialog API solve different problems: one is for light non-modal UI, the other for true modals that block the page. This post breaks down when to use each, with working code.
WordPress 7.0’s AI updates are heading into Beta 2. This post covers the pivot away from the Abilities API, the new Connector Screen, and the dependency issues in the AI Experiments plugin.
Context engineering means filling an AI model’s context window with your own domain knowledge, using structured graphs, deterministic tools, and persistent memory instead of simple RAG.
