Only a product with at least 30 evaluated sessions in the period, and at least one in the period before, appears, and the shares compare rounded to 0.1 %. ## OpenAPI ````yaml https://api.galtea.ai/openapi.json get /analytics/changes openapi: 3.0.0 info: version: 1.0.0 title: Product Management Service API description: API documentation for Product Management Service contact: name: Galtea AI servers: - url: https://api.galtea.ai security: - bearerAuth: [] tags: [] externalDocs: description: Galtea Platform Documentation url: https://docs.galtea.ai paths: /analytics/changes: get: tags: - analytics summary: List the products whose share of critical failures went up description: >- The products the caller may read that the filters keep whose share of evaluated sessions with a critical failure went up against the period of the same length just before it, the largest rise first, at most 5.
