RubyLLM 2.1.1

RubyLLM 2.1.1 fixes fresh installs that today's faraday-net_http 3.5.0 release broke, connects to MCP servers that predate the 2026-07-28 revision, and keeps batch embeddings paired with the right inputs.

bundle add ruby_llm --version 2.1.1

Already on 2.1? Run bundle update ruby_llm. No schema or code changes are needed.

Fixed

• Install RubyLLM with the latest faraday-net_http. faraday-net_http 3.5.0 falls outside the range every Faraday from 2.0.1 to 2.14.4 accepts, so a fresh bundle install resolved Faraday 2.0.0, which loads no default adapter, and every request failed with :net_http is not registered on Faraday::Adapter. RubyLLM now excludes Faraday 2.0.0. By @crmne; thanks @juneira. (ef2bebdb)
• Connect to MCP servers that predate the 2026-07-28 revision. A server that rejects the revision with -32022 now gets the initialize handshake whether it lists the legacy revisions it speaks, as Atlassian's does, or lists none, as Datadog's does. By @ebeigarts, @juneira, and @crmne. (#1056, #1057, #1053, #1055)
• Pair batch embeddings with the right inputs. OpenAI-compatible and Mistral batch results now place each vector by the position the provider reports, and mark a result with duplicate, missing, or out-of-range positions as failed instead of pairing its vectors with the wrong texts. By @D41910. (#1051, #1052)
• Keep the Bedrock inference profile you choose. An id that already names a geography, such as eu.anthropic.claude-sonnet-5-5, is no longer rewritten to another region's profile, so requests stay where your IAM policy allows them. By @s-andringa. (#1050)
• Keep chat replies when a usage row cannot be linked. A persisted chat saves the reply and logs the failed link, instead of rolling back an answer the provider already billed. By @yorzi. (#1048, #1049)
• Upload converted attachments again after a provider deletes them. The chat forgets the stale upload and retries, as it already did for plain attachments. By @yorzi. (#1046, #1047)

Thanks
