What is Prometheus?

Prometheus 3.16 ships GA with query cost limits behind a flag and stable Smoothed/Anchored selectors

Prometheus 3.16.0 went GA on 4 November after four release candidates. It makes Smoothed and Anchored vector selectors stable and always-on, adds experimental query cost estimation with configurable execution limits, an experimental integral() function, per-query start-timestamp overrides and metadata-wal-records in Agent mode. The rest is TSDB correctness fixes for out-of-order samples and a long list of scrape and remote-write performance work.

What is Zellij?

Zellij is patching the shell-aware rewrite it shipped eight days ago.

Zellij 0.45.0 pushed the multiplexer past byte-shuttling: nested sessions became a supported workflow, the Kitty graphics protocol landed, and OSC 133 parsing gave it prompt-aware scrollback. 0.45.1 arrived eight days later to fix what that surface broke — SSH nested-session detection, OSC9 notifications misfiring against the OSC99 spec, and Kitty image clearing on stacked panes. The project is single-maintainer and funds itself through sponsorship.

Prometheus 3.16 ships GA with query cost limits behind a flag and stable Smoothed/Anchored selectors

◆ Current state

Prometheus 3.16.0 went GA on 4 November after four release candidates. It makes Smoothed and Anchored vector selectors stable and always-on, adds experimental query cost estimation with configurable execution limits, an experimental integral() function, per-query start-timestamp overrides and metadata-wal-records in Agent mode. The rest is TSDB correctness fixes for out-of-order samples and a long list of scrape and remote-write performance work.

◆ Where it's heading

The 3.16 cycle makes PromQL cost measurable before making it enforceable: subquery samples now count toward statistics, and limits ship behind --enable-feature=query-cost. Remote Write 2.0 keeps dropping legacy metadata metrics, and the 3.15.x and 3.13 LTS lines move separately on security rebuilds.

◆ Prediction

Expect 3.15.x and 3.13.x security patches next and a 3.17 rc within weeks; whether query-cost leaves its flag depends on feedback the entries do not yet show.

Zellij is patching the shell-aware rewrite it shipped eight days ago.

◆ Current state

Zellij 0.45.0 pushed the multiplexer past byte-shuttling: nested sessions became a supported workflow, the Kitty graphics protocol landed, and OSC 133 parsing gave it prompt-aware scrollback. 0.45.1 arrived eight days later to fix what that surface broke — SSH nested-session detection, OSC9 notifications misfiring against the OSC99 spec, and Kitty image clearing on stacked panes. The project is single-maintainer and funds itself through sponsorship.

◆ Where it's heading

The arc runs from platform reach to terminal semantics. 0.44.0 took the multiplexer to native Windows; 0.45.0 taught it to read shell protocol rather than relay bytes. The 0.45.1 fixes cluster entirely on the protocol work, which is the expected cost of parsing escape sequences other tools emit loosely. Notably, 0.45.1 also adds escape hatches — scroll_mode_sync and explicit_theme_hue — suggesting the new defaults were more opinionated than some users wanted.

◆ Prediction

Expect 0.45.x to keep converging on OSC parsing edge cases, and expect the prompt-aware scrollback from OSC 133 to be built on next — command-level history or output capture is the obvious payoff for parsing prompt boundaries at all.
