Prometheus Alertmanager vs Lima: at a glance
What is Prometheus Alertmanager?
Alertmanager 0.34.2 turns off CORS by default, breaking cross-origin API calls.
Alertmanager handles deduplication, grouping, silencing and routing of Prometheus alerts. 0.34.2 (October 29) stops sending CORS headers by default, so cross-origin calls to api/v2 now fail unless --web.cors.origin is set, and rebuilds with Go 1.26.10 to distrust the compromised eMudhra intermediates. 0.34.1 fixed inhibitions that could un-mute alerts, and 0.34.0 split auth and rate-limit failures out of the clientError metric reason.
What is Lima?
Lima 2.3 nears release, with a Windows path that drops QEMU and a new TUI
Lima v2.3.0-rc.0 is out with an experimental HCS driver that removes the QEMU dependency on Windows hosts, block device attachment for VZ guests on macOS, and experimental shared, host and bridged networks on Linux hosts. limactl menu adds a menu-based interface, which now opens when limactl runs on a terminal without arguments. The default Ubuntu template moves to 26.10.

◆ Current state
Alertmanager handles deduplication, grouping, silencing and routing of Prometheus alerts. 0.34.2 (October 29) stops sending CORS headers by default, so cross-origin calls to api/v2 now fail unless --web.cors.origin is set, and rebuilds with Go 1.26.10 to distrust the compromised eMudhra intermediates. 0.34.1 fixed inhibitions that could un-mute alerts, and 0.34.0 split auth and rate-limit failures out of the clientError metric reason.
◆ Where it's heading
The 0.3x line keeps shipping breaking changes outside major versions: metric reason splits in 0.34.0, per-group markers in 0.33.0 and now a CORS default in a patch. Operators need to read every release note, not just minors.
◆ Prediction
Expect 0.35.0 to carry further breaking changes in the vein of 0.33 and 0.34, though the entries do not say what it will contain.
Lima
5.0INFRA · APIS
Lima 2.3 nears release, with a Windows path that drops QEMU and a new TUI
◆ Current state
Lima v2.3.0-rc.0 is out with an experimental HCS driver that removes the QEMU dependency on Windows hosts, block device attachment for VZ guests on macOS, and experimental shared, host and bridged networks on Linux hosts. limactl menu adds a menu-based interface, which now opens when limactl runs on a terminal without arguments. The default Ubuntu template moves to 26.10.
◆ Where it's heading
The any-guest, any-host direction now reaches all three desktop platforms in one release, and each host gets a feature suited to its own virtualization stack. The menu interface is a different kind of addition: it aims at people who do not want to memorize the CLI. LFX mentees and outside contributors continue to carry much of this work, and the project's experimental-first labeling still applies to the biggest items.
◆ Prediction
A 2.3.0 final is the next step after rc.0. The HCS driver and Linux network modes should stay experimental there, following the pattern earlier platform additions took.
