Liming Gao closed the quiet period on devel #122115 (Fri 21 Aug 2026 01:29:29 -0700). Next planned tag is edk2-stable202611. Public rc1/rc2/rc3 tags were never published (404).
In-tree BREAKING-CHANGES.md for this milestone lists no behavioral break. Source-level: AArch64 exception handling moved ArmPkg to UefiCpuPkg (#12340); PrePiLib firmware-volume helpers gained parameters (#12672); RISC-V timer library split SEC/DXE (#12210); TPM2 helpers moved into Tpm2HelpLib (deprecation active, #11634, #12797). New GptLib dependency so PartitionDxe and the measured-boot libraries parse one GPT (#12745); the file cites CVE-2024-13745 for the old split parsers. Build-system: GenFv ForceRebase can honor a per-module Xip flag (#12551, compat fix #12807); VS2015 and VS2017 toolchains removed (#12683).
No new GHSA in this window. Newest public advisories remain 2025-12-09 (GHSA-q2c6-37h5-7cwf, GHSA-6pp6-cm5h-86g5). CVE map Last-Modified still Wed, 15 Jul 2026 22:05:38 GMT. Master has moved since the tag; those commits are their own cards.
