• Attachment count rose from 2 to 5, with 3 files added and none removed.
• The three new attachments are unnamed in the change record (filenames and resource IDs are null), so their titles and content cannot be confirmed from this change alone.
• Applicants should open all three from the solicitation page to find out whether they are amendments, instructions, forms, templates, or technical appendices.
• Why it matters: new attachments often carry requirements that change the response, such as revised specifications, required forms, or updated evaluation criteria. Check whether any of them alter deadlines or submission format, and compare them against the existing two attachments before drafting or pricing a response.

The close date moved from October 12, 2026 at 7:00 PM UTC to October 14, 2026 at 7:00 PM UTC, a two-day extension.

Applicants now have two additional days to submit, which gives more time to finalize proposals, assemble supporting documents, and complete any registration steps. Teams planning around the earlier deadline should update their internal schedules, but no requirements or eligibility criteria appear to have changed based on this edit.
