Stalwart
1.0: a full Rust mail stack — pin your Docker tag first
Stalwart 1.0 ships IMAP, POP3, SMTP, JMAP, CalDAV, CardDAV and
WebDAV. Against Postfix 3.11 and Dovecot 2.4 it claims wins on 35 of 38
metrics — inbound SMTP 3.6–12× faster, IMAP login 5× faster — through
SIMD/SWAR parsers and a redesigned full-text search engine. New: search
inside PDF/Office/EPUB attachments, OAuth/OIDC with per-client scopes,
and post-quantum DKIM2 signatures (ML-DSA-44 + Ed25519).
The catch: 1.0 cannot open a 0.16 store, and latest
already points to 1.0. Anyone on watchtower gets a broken mail server on
the next pull. Pin v0.16 now and migrate deliberately on a
copy of the data — done that way, the migration reportedly goes
fine.

7.3’s eBPF binfmt_misc hooks: a path to relocatable Nix binaries
A Discourse thread explores using Linux 7.3’s eBPF-powered
binfmt_misc hooks to give Nix binaries and scripts
$ORIGIN-relative interpreter paths alongside their absolute
/nix/store paths, so the store could move without breaking
executables. The proposal adds a PT_INTERP_NIX ELF section,
with the absolute path as fallback on older kernels. fzakaria, co-author
of the kernel patches, plans a NixOS module for the eBPF handler and
wants to propose the pattern to Debian and Fedora.
Determinate
sells emergency security coverage for NixOS 25.05
NixOS 25.05 has been unpatched since December 2025, leaving hundreds
of CVEs open across curl, OpenSSL, Node, PHP and Brotli
(CVE-2026-111497, RCE). Prompted by this week’s disclosures, Determinate
launched a paid Emergency Legacy Extension with its usual
CVE-remediation SLA, guaranteed through Q4 2027. It starts at roughly
1,000 packages and includes FlakeHub cache access and CycloneDX
SBOMs.
HACS
becomes the Home Assistant Marketplace in 2026.11
From HA 2026.11, due in about ten days, HACS is built in under
Settings → Marketplace. Everything migrates automatically and stays
free; installing an integration drops you straight into its setup flow
without a restart. Standalone HACS can no longer be installed on
2026.11+. If you were about to install HACS: wait.
Ukishima:
a dynamic-island Quickshell for Hyprland and Niri
A morphing pill at the top of each monitor expands in place into a
launcher, system monitor, media controls, mixer, clipboard history,
wallpaper and emoji pickers, or power menu. A dock with hover
magnification and window previews sits at the bottom, plus a lock
screen, per-output OSD, screen recorder and timer. It never touches your
compositor config beyond the launch line. MIT licensed.
