The Theta Terminal itself is date-versioned (e.g. version 20260615 required for API-key auth) and auto-updates on startup with automatic fallback to the previous version on failure. deprecation: policy_url: https://docs.thetadata.us/Articles/Getting-Started/v2-migration-guide.html sunset_header: false notes: >- v2 endpoints are superseded by v3; the migration guide maps every v2 endpoint and parameter to its v3 replacement and lists removed features (e.g. /v2/hist/stock/split and /v2/hist/stock/dividend are "Coming Soon" in v3; bulk requests replaced by * wildcards; the v2 next-page pagination header was eliminated in v3). No RFC 8594 Sunset/Deprecation headers are documented. sla: url: null uptime_target: null notes: No public SLA published; support is via Discord. status_page: https://thetadata.statuspage.io/ roadmap: https://thetadata.net/roadmap deprecated_operations: [] notes: >- No operation in the v3 OpenAPI is marked deprecated: true.
