Mastra @mastra/core 1.73.0: default stability errorProcessors; tool-call-resumed chunk; rewrite invalid Anthropic tool-call IDs

Mastra published @mastra/[email protected] on 2026-10-01 (~08:36Z; 124 commits vs 1.72.0): default stability errorProcessors (ProviderHistoryCompat, PrefillErrorHandler, StreamErrorRetryProcessor); new tool-call-resumed stream chunk; rewrite invalid Anthropic tool-call IDs outbound; export findGatewayForModel/getGatewayId; subagent model resolution with caller requestContext.

Key Takeaways

npm @mastra/[email protected] at 2026-10-01T08:36:38Z; 124 commits vs 1.72.0
Default errorProcessors (#24473): history compat → prefill handler → stream retry; opt out with errorProcessorDefaults:false
New tool-call-resumed chunk (#25491) before tool-result for suspend/approval resumes
Rewrite invalid Anthropic tool-call IDs outbound (#24505); export findGatewayForModel/getGatewayId
npm i @mastra/[email protected]; https://mastra.ai/docs

Mastra @mastra/core 1.72.0: live channel resolvers, lease-fenced background tasks, Microsoft Teams channel

Mastra shipped @mastra/[email protected] on 2026-09-30: live channel resolvers, lease-fenced background tasks, durable/evented recovery, aggregateTraces(), and @mastra/teams. Breaking: respondToToolApproval requires toolCallId.

Key Takeaways

Release @mastra/[email protected] at 2026-09-30T10:31:27Z
Live channels() resolvers + resolveChannels() avoid redeploys
Lease-fenced background tasks with ownerId + expectedOwnerId writes
New @mastra/[email protected] and 25 Teams tools in Connect
Breaking: respondToToolApproval requires toolCallId

Mastra @mastra/core 1.71.0: eager tool execution by default, plus observability discovery/feedback features

Mastra shipped @mastra/core 1.71.0 on 2026-09-24: agent.stream starts each tool as soon as its args complete (eagerToolExecution on by default), cutting idle seconds on multi-tool steps; adds planTraceAggregate(), observability getFeatures discovery/feedback flags, and RE2-backed dataset schema regexes to close a DoS vector.

Key Takeaways

Default: tools start when their streamed args complete; opt out with eagerToolExecution: false (#25005)
Observability stores declare discovery + feedback via getFeatures() (#25008, #25020)
planTraceAggregate(): ≤365d range, ≤1000 buckets, ≤10,000 rows (#24868)
Dataset schema regexes run on RE2; unsupported lookarounds/backrefs rejected (#25044)
Upgrade: npm i @mastra/[email protected]

Mastra @mastra/core 1.70.0: ModelSelectionProcessor routes cheap vs strong models; durable streams gain closeOnSuspend

Mastra published @mastra/[email protected] on 2026-09-24 with ModelSelectionProcessor for classifier-backed per-request model routing (#24865), closeOnSuspend on durable agent streams so AG-UI-style loops can finish on tool suspend, plus createClassifierScorer(), optional tool titles, and trace aggregate dimension/measure helpers with tag predicates. Docs warn routing is not always cheaper because models do not share prompt caches.

Key Takeaways

ModelSelectionProcessor routes simple vs hard requests (#24865); scope: 'first-step' optional
Durable closeOnSuspend: true ends streams at tool suspend (#24894)
createClassifierScorer() maps Classifier questions to 0–1 scores (#24792)
Trace aggregate descriptors + tag predicates for advanced queries
Upgrade: npm i @mastra/[email protected]; see CHANGELOG + processors docs

Mastra @mastra/core 1.69.0: first-class classifiers, fail-closed ClassifierProcessor, background.adopt, 10 Connect providers

Mastra shipped @mastra/[email protected] on 2026-09-24: register classifiers on new Mastra({ classifiers }) and use them as typed workflow steps; ClassifierProcessor fails closed by default on I/O/stream; tools can context.background.adopt() long work; @mastra/connect adds ten generated SaaS tool providers (Slack, GitHub, Gmail, …).

Key Takeaways

@mastra/[email protected] tagged 2026-09-24 06:58 UTC (npm also rolled 1.70.0 later that day)
First-class classifiers with list/add/remove and typed workflow steps + token usage
ClassifierProcessor fails closed by default; opt into errorStrategy: 'warn'
context.background.adopt({ completion, cancel }) for ack-then-finish tools (in-memory handles)
@mastra/[email protected] ships 10 generated providers (Slack, GitHub, Gmail/Calendar, …)
