Release binary trimmed from 34 MB to 26 MB (~24% smaller). Switched jsonwebtoken to its rust_crypto backend (eliminates our scanner's pull on aws-lc-rs), bumped workspace hmac 0.12→0.13, sha1 0.10→0.11, sha2 0.10→0.11 to deduplicate our internal crypto code with the AWS sigv4 side, and migrated affected call sites in kingfisher-core, kingfisher-rules, and kingfisher-scanner to the digest-0.11 API (hex::encode for hex digests, explicit KeyInit import for HMAC).

 - Git repository scans now extract archive blobs encountered in the object database, not just on the filesystem. Previously a `.zip`/`.jar`/`.apk`/`.tar.gz` committed to a repo was scanned as raw compressed bytes, so secrets inside it were invisible. The git enumerator fans each archive entry out as a synthetic `<archive>!<entry>` blob with the original commit metadata. Honors `--no-extract-archives` for opt-out.
 - Performance: ZIP-based git blobs ≤ 64 MB extract entirely in memory (no temp-file round trip), beating the v1.99.0 baseline by ~15% on a 80 GiB monorepo despite scanning ~300K additional archive-content blobs. Larger archives auto-fall-back to a disk-streaming extractor.
 - Memory safety: hard caps on archive extraction — 64 MB compressed pre-flight, 256 MB aggregate decompressed per archive (in-memory and disk paths), 512 MB per entry, plus a `PK\x03\x04` magic-byte gate. Worst-case footprint is bounded at ~`num_jobs * 320 MB`.
+- Release binary trimmed from 34 MB to 26 MB (~24% smaller). Switched `jsonwebtoken` to its `rust_crypto` backend (eliminates our scanner's pull on `aws-lc-rs`), bumped workspace `hmac` 0.12→0.13, `sha1` 0.10→0.11, `sha2` 0.10→0.11 to deduplicate our internal crypto code with the AWS sigv4 side, and migrated affected call sites in `kingfisher-core`, `kingfisher-rules`, and `kingfisher-scanner` to the digest-0.11 API (`hex::encode` for hex digests, explicit `KeyInit` import for HMAC).

 ## [v1.99.0]
 - Fixed [#371](https://github.com/mongodb/kingfisher/issues/371): `pip install kingfisher-bin` on glibc Linux distros (Ubuntu, Debian, RHEL, Fedora, …) installed a macOS Mach-O binary and failed with `OSError: [Errno 8] Exec format error`. Linux wheels are now tagged `manylinux_2_17_<arch>.musllinux_1_2_<arch>` (instead of `musllinux_1_2_<arch>` only), so pip accepts them on both glibc-2.17+ and musl distros. The `pypi/hatch_build.py` hook now hard-fails when `KINGFISHER_PYPI_WHEEL_TAG` is unset, and the publish workflow refuses to upload any `py3-none-any.whl`, so the v1.92.0-era pure-Python wheel cannot recur.

+## [v1.100.0]
+- Archive scanning now reaches inside Android/iOS app packages: added `apk`, `aab`, and `ipa` to the recognized ZIP-based archive formats so secrets embedded in APK/AAB/IPA contents (e.g. `classes*.dex`, `res/values/strings.xml`) are extracted and matched.
+- Git repository scans now extract archive blobs encountered in the object database, not just on the filesystem. Previously a `.zip`/`.jar`/`.apk`/`.tar.gz` committed to a repo was scanned as raw compressed bytes, so secrets inside it were invisible. The git enumerator fans each archive entry out as a synthetic `<archive>!<entry>` blob with the original commit metadata. Honors `--no-extract-archives` for opt-out.
+- Performance: ZIP-based git blobs ≤ 64 MB extract entirely in memory (no temp-file round trip), beating the v1.99.0 baseline by ~15% on a 80 GiB monorepo despite scanning ~300K additional archive-content blobs. Larger archives auto-fall-back to a disk-streaming extractor.
+- Memory safety: hard caps on archive extraction — 64 MB compressed pre-flight, 256 MB aggregate decompressed per archive (in-memory and disk paths), 512 MB per entry, plus a `PK\x03\x04` magic-byte gate. Worst-case footprint is bounded at ~`num_jobs * 320 MB`.
+- Release binary trimmed from 34 MB to 26 MB (~24% smaller). Switched `jsonwebtoken` to its `rust_crypto` backend (eliminates our scanner's pull on `aws-lc-rs`), bumped workspace `hmac` 0.12→0.13, `sha1` 0.10→0.11, `sha2` 0.10→0.11 to deduplicate our internal crypto code with the AWS sigv4 side, and migrated affected call sites in `kingfisher-core`, `kingfisher-rules`, and `kingfisher-scanner` to the digest-0.11 API (`hex::encode` for hex digests, explicit `KeyInit` import for HMAC).

 ## [v1.99.0]
 - Fixed [#371](https://github.com/mongodb/kingfisher/issues/371): `pip install kingfisher-bin` on glibc Linux distros (Ubuntu, Debian, RHEL, Fedora, …) installed a macOS Mach-O binary and failed with `OSError: [Errno 8] Exec format error`. Linux wheels are now tagged `manylinux_2_17_<arch>.musllinux_1_2_<arch>` (instead of `musllinux_1_2_<arch>` only), so pip accepts them on both glibc-2.17+ and musl distros. The `pypi/hatch_build.py` hook now hard-fails when `KINGFISHER_PYPI_WHEEL_TAG` is unset, and the publish workflow refuses to upload any `py3-none-any.whl`, so the v1.92.0-era pure-Python wheel cannot recur.
 - `--self-update` (alias `--update`) on a scan or other command now **re-execs into the freshly installed binary** so the current invocation completes with the new code and the latest detection rules. Previously the on-disk binary was replaced but the running process kept using the old in-memory version, requiring a second invocation to pick up the changes. On Unix this is a true `exec()` (same PID); on Windows the new binary is spawned and the parent exits with its status code. The explicit `kingfisher self-update` subcommand still updates and exits without re-execing. Self-update now also covers Windows arm64 (the asset was already published; the runtime cfg map gained the missing arm). See `docs/ADVANCED.md` → *Update Checks*.
