opensearch-go v5.0.1

UPGRADE NOTE - v5.0.1 changes the PIT API in ways that can break a build.

• PIT ID fields are typed as opensearchapi.PITID instead of string/*string. Build one with ParsePITID and read it with String. The wire format doesn't change.
• Required PIT response fields on CreatePITResp, PITDeleted, and PITDetail are values, not pointers.
• client.PIT.Delete and client.PIT.DeleteAll return a *PartialPITDeleteError when the server keeps some of the PITs they name. Mask errmask.PITDeleteItems to get the old behavior.

Before/after for each is in UPGRADING_V5.md.

v5.0.1 is the first patch on the v5 line. It adds a closable PIT handle with search_after iterators and a pluggable request Compressor, and fixes several request-body bugs.

Requires Go 1.26.8 or later.

Full Changelog: v5.0.0...v5.0.1

What's new

• client.PIT.Open returns a PIT handle that is safe for concurrent use. client.SearchAfter, client.PIT.SearchAfter, and their Pages variants page a sorted search with search_after and stop on an incomplete page instead of skipping documents. See guides/usage-search.md (#1183)
• Compressor on opensearch.Config and opensearchtransport.Config picks the request codec and level, with GZip(level) and None() built in. It replaces CompressRequestBody, which is deprecated. By @iprithv in #1180

Fixes

• fix(opensearchtransport): a failed read of the request body sent an empty or partial body instead of an error. An empty search body runs as match_all. By @iprithv in #1181
• fix(opensearchtransport): CompressRequestBody gzipped bodies that already had a Content-Encoding, and could corrupt a compressed body that outlived its request. By @iprithv in #1180
• fix(opensearchutil): JSONReader.Read returned leftover data with no error after an encode failure. By @iprithv in #1181
• fix(osapilint): several v4 -> v5 rewrite fixes, reported by @Jakob3xD in #1174. By @itsmeasadali and @ryanyuan in #1170, #1184, #1189

Dependencies

• Bump the go directive to 1.26.8 for the standard library CVE fixes (#1172)
• Bump the AWS SDK, smithy-go, and OpenTelemetry (#1172, #1191)
