Change-log

Official ALL change-log:

• General system stability improvements to enhance the user's experience.

System Titles

• The following titles were updated:
  • Sysmodules: account, ns, erpt, pctl, migration.
  • Applets: qlaunch.

NPDM changes (besides usual version-bump):

• migration: Service access: added eupld:c.

• SystemVersion: All files updated.

erpt

Only a single instruction was changed (besides GNU build-id). Previously, when validating the CreateReportContext in Reporter::CreateReport, Nintendo checks that FieldId_ErrorCode is present, and that the field corresponding to FieldId_ErrorCode has type == FieldType_String (ResultFieldTypeMismatch if not) and that it has size <= 0xE (ResultArrayFieldTooLarge if not).

It now checks that the error code string is size <= 0xF instead of <= 0xE.
