 ## Contract Details
 
-### v2 - Current (Since SDK 1.24.0, March 2026)
+### v8 - Current
+
+**What changed:**
+
+- `christmas_bonus` is now covered by the extreme-salary acknowledgement: a warning and a required checkbox appear when the annual salary is at or above the USD 1,000,000 equivalent. Additive and flag-gated, so no action is required unless a submitted salary crosses that threshold.
+- The Christmas bonus description now calls it the 13th month salary, typically 15 to 30 days' salary. Copy only.
+
+**Migration:**
+
+```tsx
+<OnboardingFlow
+  options={{
+    jsonSchemaVersionByCountry: {
+      MEX: { contract_details: 8 },
+    },
+  }}
+/>
+```
+
+---
+
+### v7
+
+**What changed:**
+
+- `annual_gross_salary` adds high-salary reserve messaging, grouped with `annual_bonus_ack` and `ergonomic_chair_ack` in a fieldset titled "Annual gross salary" (now driven by the field's presentation settings instead of `annual_gross_salary_fieldset`). Additive and flag-gated.
+- The form moves to the JSON Schema Form v1 engine. Validation and form generation follow v1 semantics.
+
+**Migration:**
+
+```tsx
+<OnboardingFlow
+  options={{
+    jsonSchemaVersionByCountry: {
+      MEX: { contract_details: 7 },
+    },
+  }}
+/>
+```
+
+---
+
+### v6
+
+**What changed:**
+
+- Admin-only fixed-term contracts: `contract_duration_type` is still indefinite-only for employers, but Remote Admins can set a fixed term with unlimited maximum duration.
+- `contract_end_date` and its "deprecated, Mexico doesn't allow fixed-term" definition are removed from the schema (inferred from the schema diff).
+
+**Migration:**
+
+```tsx
+<OnboardingFlow
+  options={{
+    jsonSchemaVersionByCountry: {
+      MEX: { contract_details: 6 },
+    },
+  }}
+/>
+```
+
+---
+
+### v5
+
+**What changed:**
+
+- The `non_compete`, `non_solicitation` and `non_interference` components added in v4 are removed again. Payloads must not send non-compete fields.
+
+**Migration:**
+
+```tsx
+<OnboardingFlow
+  options={{
+    jsonSchemaVersionByCountry: {
+      MEX: { contract_details: 5 },
+    },
+  }}
+/>
+```
+
+---
+
+### v4
+
+**What changed:**
+
+- Adds the shared `non_compete`, `non_solicitation` and `non_interference` components after the contract duration fields (inferred from the schema diff).
+
+**Migration:**
+
+```tsx
+<OnboardingFlow
+  options={{
+    jsonSchemaVersionByCountry: {
+      MEX: { contract_details: 4 },
+    },
+  }}
+/>
+```
+
+---
+
+### v3
+
+**What changed:**
+
+- Adds the required `ergonomic_chair_ack` acknowledgement: the employer confirms they will reimburse up to 3,000 MXN for an ergonomic chair if the employee works remotely. Submits that omit it fail validation.
+- The indefinite-only contract duration is now expressed with `indefinite_duration_only` instead of `contract_duration_options` and a forced-value statement (inferred from the schema diff).
+
+**Migration:**
+
+```tsx
+<OnboardingFlow
+  options={{
+    jsonSchemaVersionByCountry: {
+      MEX: { contract_details: 3 },
+    },
+  }}
+/>
+```
