[Graduated to 'master']

* ak/sequencer-head-refdup (2026-10-14) 1 commit
  (merged to 'next' on 2026-10-19 at 2ff8066fce)
 + sequencer: don't clobber HEAD ref name in worktree lookup

 The branch decoration logic in the sequencer has been updated to use
 an allocated buffer for the HEAD reference name, preventing it from
 being clobbered when evaluating branches checked out in other
 worktrees.

* ic/includeif-hostname (2026-10-15) 3 commits
  (merged to 'next' on 2026-10-19 at dc388c8226)
 + config: learn the "hostname:" includeIf condition
 + t6500: get hostname from "git var"
 + var: add GIT_HOSTNAME

 The conditional configuration inclusion mechanism via 'includeIf'
 has been extended to support matching the machine's hostname, and
 the system's hostname as seen by Git can now be queried using 'git
 var GIT_HOSTNAME'.

  (merged to 'next' on 2026-10-19 at 67e49ef79c)
 + doc: use `man git` to teach users how to navigate the docs

 The earliest part of 'man git' has been rewritten to explain various
 ways to use 'git help' to get help.

  (merged to 'next' on 2026-10-19 at 7dfc4734f0)
 + fast-import: allow 'from' to reference new commits and tags by oid

 The 'from' command in 'git fast-import' has been updated to
 correctly resolve references to newly created commits and tags by
 checking the internal object table, preventing a crash when the
 objects are not yet available in the object database.

  (merged to 'next' on 2026-10-19 at c0cf13277b)
 + ci: improve reftable test coverage
 + ci: drop now-dead Python 2 coverage
 + ci: switch away from EOL'd Ubuntu version in linux-feature-testbed
 + ci: rename linux-TEST-vars job
 + ci: switch away from unsupported i386/ubuntu image
 + ci: drop unused "linux-clang" logic
 + ci: fix "fedora-breaking-changes-meson" job
 + t5004: fix test creating an archive with large objects under SHA256

 Various CI jobs have been updated to use modern OS images, drop dead
 code, and remove redundant jobs. Support for Python 2 in CI has been
 removed, and the linux-TEST-vars job has been renamed to
 linux-feature-testbed.

* ps/odb-files-alternates-cleanups (2026-10-14) 6 commits
  (merged to 'next' on 2026-10-19 at 242a7794ab)
 + odb/source: drop `local` flag
 + odb: don't try re-fetching corrupt objects
 + odb: remove read loop for found objects
 + odb/source-files: make the second read an implementation detail
 + odb/source-files: fix performance when streaming objects with alternates
 + odb/source-files: fix performance when reading objects with alternates
 + Merge branch 'ps/odb-files-alternates' into ps/odb-files-alternates-cleanups
 (this branch is used by ps/odb-reload-alternates.)

 The object database "files" backend has been optimized to check
 packfiles across all alternate object directories before falling
 back to checking loose objects, significantly reducing the number of
 'stat(3p)' system calls.  Additional refactoring drops the generic
 'local' flag from the object database source interface in favor of
 backend-specific fields, and simplifies the retry loop for missing
 objects.

* ps/pack-check-bigfile-threshold (2026-10-14) 1 commit
  (merged to 'next' on 2026-10-19 at d477f68a6d)
 + pack-check: fix bogus corruption report with core.bigFileThreshold

 A boundary check in 'git fsck' against the big file threshold has
 been corrected to prevent bogus corruption reports on packed objects
 whose sizes exactly match the threshold.

  (merged to 'next' on 2026-10-17 at 68944adf51)
 + setup: enforce that passed-in repo does not carry relevant state
 + repository: adapt `repo_clear()` to fully reset the repository
 + builtin/clone: don't apply "core.sharedRepository" to leading dirs
 + builtin/init: move handling of "core.sharedRepository" into "setup.c"
 + builtin/init: refactor messy creation of leading directories
 + path: introduce `safe_create_leading_directories_no_share_const()`
 + path: drop useless `safe_create_leading_directories_1()`
 + Merge branch 'ps/odb-alternates-at-creation' into ps/setup-enforce-repo-passed-to-create-repository-has-no-state
 (this branch is used by ps/odb-object-storage-extension.)

 The repository initialization sequence has been refactored to treat
 the repository object passed to create_repository() purely as an
 out-parameter.

* rm/blame-default-ignore-revs (2026-10-13) 2 commits
  (merged to 'next' on 2026-10-17 at 31af0a1889)
 + blame: ignore revs in .git-blame-ignore-revs by default
 + blame: harden ignore-revs parser and tag peeling

 'git blame' and 'git annotate' have been updated to automatically
 use the '.git-blame-ignore-revs' file from the working tree (or
 'HEAD:.git-blame-ignore-revs' in bare repositories) as the default
 ignore list if it exists, and the parser has been hardened.
