Changelog

Initial opam release, forked from solvuu/awsm, which was itself never released to opam.

Replaced the lightweight higher kinded polymorphism with a functorized approach. (End users don't need to instantiate the functors, it's already done in the library)
Restructured aws/ into aws/<service>/{async,lwt,sync}/, each backend ships only what it needs.
Eliminated the Transport variant from API responses; only AWS-side errors stay in Result, transport errors raise, similar to the convention Async follows.
As advised by opam-repository crew, consolidated the per-service opam packages into sub-libraries under each backend. opam install awso-async pulls in every service binding under awso-async.<svc>. Same for -lwt and -sync.
Pre-generate the 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. For scripts and CLIs where pulling in an async scheduler is overkill
awso-cli: for fun, an everything including the kitchen sink binary that exposes every awso-async service as a composable subcommand, similar in spirit to the python aws-cli. Ships as bytecode because linking ~400 native service libraries exceeds ARM64 executable assembly size limits
dogfood/ tools used by maintainers to develop awso

minimum OCaml is 5.0 (4.14 to be available next release!)
now on dune 3.6
removed Jane Street Core from the non-Async runtimes; non-async builds now use a very small Jane_compat shim under lib/common/
replaced ad-hoc JSON with Yojson.Safe.t everywhere

Freshened to botocore 1.43.9
Huge precomputed endpoints.json match table replaced with a memoised lookup
Output shapes treat required 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 fixes
Escape odoc special characters in generated doc comments
22 retired AWS services that were dropped from botocore
