 - Removed `deprecated: true` from LegacyTeams endpoints (`GET`/`POST /v1/legacyTeams`, `GET`/`PUT /v1/legacyTeams/{id}`, `GET`/`POST`/`DELETE /v1/legacyTeams/{id}/users`, `GET /v1/legacyTeams/user/{id}`) and updated the tag description to remove outdated deprecation notice
 
 ### Fixed
+- Fixed the comma-separated `include_fields` query parameter across v2 collection/detail endpoints (`GET /api/v2/activities`, `GET /api/v2/activities/{id}`, `GET /api/v2/activityFields`, `GET /api/v2/activityFields/{field_code}`, `GET /api/v2/deals`, `GET /api/v2/deals/{id}`, `GET /api/v2/dealFields`, `GET /api/v2/dealFields/{field_code}`, `GET /api/v2/organizations`, `GET /api/v2/organizations/{id}`, `GET /api/v2/organizationFields`, `GET /api/v2/organizationFields/{field_code}`, `GET /api/v2/persons`, `GET /api/v2/persons/{id}`, `GET /api/v2/personFields`, `GET /api/v2/personFields/{field_code}`, `GET /api/v2/productFields`, and `GET /api/v2/productFields/{field_code}`) that was typed as `type: string` with an enum of comma-joined value combinations despite accepting comma-separated lists — changed to `type: array` of enumerated strings with `uniqueItems: true`, `style: form`, `explode: false`
+- Fixed the comma-separated `custom_fields` query parameter on v2 collection/detail endpoints (`GET /api/v2/deals`, `GET /api/v2/deals/archived`, `GET /api/v2/deals/{id}`, `GET /api/v2/organizations`, `GET /api/v2/organizations/{id}`, `GET /api/v2/persons`, `GET /api/v2/persons/{id}`, and `GET /api/v2/products`) and the `ids` query parameter on v2 collection endpoints (`GET /api/v2/activities`, `GET /api/v2/deals`, `GET /api/v2/deals/archived`, `GET /api/v2/organizations`, `GET /api/v2/persons`, and `GET /api/v2/products`) that were typed as `type: string` despite accepting comma-separated lists — changed to `type: array` of strings (`custom_fields` capped at 15 items, `ids` at 100) with `uniqueItems: true`, `style: form`, `explode: false`
 - Fixed `has_pic` field type in v1 deal creator schema (`DealNonStrictModeFields`, used by `GET`/`POST /v1/deals` and related endpoints) — changed from `boolean` to `integer` since the API returns `0`/`1`, not `true`/`false`
 - Fixed `code` field type in v2 product search results (`GET /api/v2/products/search`) — changed from `integer` to `string` and made nullable to match actual API responses
 - Fixed `value` field type in v2 deal search results (`DealSearchItem`, used by `GET /api/v2/deals/search`) — changed from `integer` to `number` and made nullable to match actual API responses

 - Reworded the `im`, `notes`, `birthday`, and `job_title` field descriptions and the `addPerson`/`updatePerson` operation descriptions (which also cover `postal_address`) to disclose that these fields 403 when contact sync isn't enabled, rather than only describing when they're present on read.
 - Fixed OAuth scopes on six v2 deal sub-resource write operations (`POST /api/v2/deals/{id}/discounts`, `PATCH`/`DELETE /api/v2/deals/{id}/discounts/{discount_id}`, `POST /api/v2/deals/{id}/installments`, `PATCH`/`DELETE /api/v2/deals/{id}/installments/{installment_id}`) that incorrectly listed `deals:read` alongside `deals:full`, copied from their sibling GET operations - these are now `deals:full` only, matching their read-write nature
