What is Alacritty?

Alacritty ships twice a year and spends it on config syntax, Wayland and IME.

The feed interleaves two things: application releases and tags for the alacritty_terminal library crate, the latter carrying no release notes at all. The one substantive release in this window, 0.17.0, adds mouse wheel bindings, TOML 1.1 syntax support, and window.resize_increments on Wayland, alongside IME behavior changes on X11 and touch input and a new escapes manpage. Before it, 0.16.1 was a single crash fix for GPUs with partial robustness support.

What is Prometheus?

Prometheus 3.14 ships the release candidate unchanged, duration expressions now on by default

3.14.0 is byte-identical to the 3.14.0-rc.0 body published a week earlier, so the stable cut carries exactly what the candidate previewed: PromQL duration expressions enabled by default with the feature flag retired, first_over_time promoted to stable, Oracle Cloud service discovery added, and a set of start-timestamp experiments still behind flags. The performance work is the substantive half, with regex matchers on literal alternations, native histogram scrape parsing down roughly 49% in allocations, and a recursion-free text parser that closes a stack-overflow path on hostile exposition.

Alacritty vs Prometheus: editorial side-by-side

Alacritty ships twice a year and spends it on config syntax, Wayland and IME.

◆ Current state

The feed interleaves two things: application releases and tags for the alacritty_terminal library crate, the latter carrying no release notes at all. The one substantive release in this window, 0.17.0, adds mouse wheel bindings, TOML 1.1 syntax support, and window.resize_increments on Wayland, alongside IME behavior changes on X11 and touch input and a new escapes manpage. Before it, 0.16.1 was a single crash fix for GPUs with partial robustness support.

◆ Where it's heading

This is a mature terminal emulator on a deliberately slow cadence, and the work concentrates where the platform underneath keeps moving: Wayland window sizing, input method handling across X11 and touch, and GPU driver edge cases. Configuration is the other thread, with TOML syntax support advancing and more of the terminal's behavior becoming bindable. Every application release ships a release candidate carrying an identical change list first.

◆ Prediction

Recent additions are all bindings and configuration surface rather than terminal features, and the library crate is versioned separately on its own cadence; more of the same incremental configurability is what these entries support, on a timeline measured in months.

Prometheus 3.14 ships the release candidate unchanged, duration expressions now on by default

◆ Current state

3.14.0 is byte-identical to the 3.14.0-rc.0 body published a week earlier, so the stable cut carries exactly what the candidate previewed: PromQL duration expressions enabled by default with the feature flag retired, first_over_time promoted to stable, Oracle Cloud service discovery added, and a set of start-timestamp experiments still behind flags. The performance work is the substantive half, with regex matchers on literal alternations, native histogram scrape parsing down roughly 49% in allocations, and a recursion-free text parser that closes a stack-overflow path on hostile exposition.

◆ Where it's heading

The project is spending its feature budget on start timestamps, appearing across PromQL, TSDB encoding, and remote write V2 in the same release but held behind use-start-timestamps and histograms-st-encoding. Everything else follows the established rhythm of promoting one experimental function per cycle and adding a cloud discovery source. The API deprecations are being staged carefully, warning now and rejecting at the next major.

◆ Prediction

Start timestamps are the obvious candidate to lose their feature flags once the encoding and remote-write halves have run together, and the stats parameter values now warned on will be rejected in the next major.
