awso-eio: backend for Eio. Same 400+ services exposed as awso-eio.<svc>. Requires OCaml 5CREDITS.mdtls >= 2.1.0. Noticed CVE-2026-45388 (TLS 1.3 client missing keyUsage/extendedKeyUsage validation), decided to get ahead of it.mirage-crypto-rng >= 1.2.0 for Mirage_crypto_rng_unix.use_default (the now-deprecated initialize is gone in our usage)async_ssl constrained to the -2 opam-repository revisions that re-add -Wno-implicit-function-declaration. The intermediate -1 revisions only suppressed -Wno-incompatible-pointer-types, which left the build broken on distros where OpenSSL ships without the deprecated ENGINE_* API (e.g. centos-10). Fixed upstream in ocaml/opam-repository#29939 and the corresponding source-archives PR. Note: this is broken where async_ssl is attempted on systems that have completely removed openssl/engine.h. Upstream should probably remove it.core_unix, ppx_jane, async floored at v0.16.0 to match what we actually test againstenum field on shape membershttpChecksumRequired operation trait (currently ignored since we don't auto-compute checksums; users still set ?contentMD5 themselves with Awso.Client.content_md5_insecure as a helper)Initial opam release, forked from solvuu/awsm, which was itself never released to opam.

Same for -lwt and -sync.aws/ tree and commit it. opam install no longer runs the codegen, which means end users require ~25 less packages in their dependency cone.awso-sync: synchronous (blocking) backend implemented over libcurl.

Ships as bytecode because linking ~400 native service libraries exceeds ARM64 executable assembly size limitsdogfood/ tools used by maintainers to develop awsoCore from the non-Async runtimes; non-async builds now use a very small Jane_compat shim under lib/common/Yojson.Safe.t everywhereendpoints.json match table replaced with a memoised lookuprequired as advisory. AWS itself routinely omits fields it marks required (AccessDeniedException with no Message, GeocodeResponse with no PricingBucket), so deserializers don't blow up when the service lies about its own spec. Input shapes still respect required. shim for newer services whose hostname doesn't follow endpointPrefix conventions (geo-places, geo-maps, geo-routes, iot-data, sso). snake-case and endpoint name/wire name fixesSee TODO.md for things known to still be rough
