v1.5.5

Released at 2026-08-31

• Grantify and FreeBet Systems:
  • Added scheduled validity using effected_at and expired_at; both timestamps must be ordered whole-hour Unix timestamps with a duration of 1 to 168 hours
  • Kept the existing validity_hours mode for compatibility; when the two timestamps are provided, they take precedence and validity_hours is ignored
  • New Grantify and FreeBet records are created in Pending state (0) and automatically become Active (1) after effected_at
  • Create and query responses now include effected_at; FreeBet create responses also include created_at and expired_at
• Grantify System:
  • Create Grantify now accepts the optional base_spin_rtp parameter (range [60, 140], used to select the Base Spin RTP table) and rtp_auto parameter (adaptively adjusts contLevel during wagering based on the wagering multiple when enabled)
