+ReleaseNotes: |-
+  A small release that recognizes loongarch64 and riscv64 as valid platform arches and refreshes the conda (rattler) backend.
+  Fixed
+  - Add loongarch64 and riscv64 to the set of arches accepted by Platform::validate(). Previously, lockfiles targeting linux-riscv64 or linux-loongarch64 would fall back to the common platform set instead of resolving to the requested single platform, so installs on those machines couldn't use lockfile-authoritative platform selection (#10038 by @k0tran).
+
+  Changed
+  - Bump rattler (used by the conda backend) from 0.42 to 0.43, picking up upstream fixes for missing symlinks during Windows installs, deterministic path ordering from link_package_sync, and accepting full URLs as the OAuth issuer host (#10030).
+
+  New Contributors
+  - @k0tran made their first contribution in #10038
+
+  💚 Sponsor mise

+  If mise saves you or your team time, please consider sponsoring at en.dev. Individual and company sponsorships keep mise fast, free, and independent.
