🔴 UPDATE: Base Branch Issue Discovered

PR #1808 Status: Base branch mismatch identified

Issue

PR #1808 is currently targeting master branch instead of beta_6_0. The merge is blocked until this is corrected.

What This Means

• ✅ Code has been reviewed and approved
• ✅ Build passes successfully
• ❌ Cannot merge in current state (wrong base branch)
• ⏳ Requires maintainer action to change base

Action Required

Priority: IMMEDIATE - Deadline is 36 hours away

1. Maintainer must change PR base from master → beta_6_0
2. Once base is changed, merge can proceed immediately
3. Security patch will be in place before deadline

Timeline Impact

• Current Time: 2026-03-29 23:21 UTC
• Deadline: 2026-03-31 00:00 UTC
• Remaining: ~36 hours
• Status: ON TRACK if base branch fixed now

Next Steps

1. Change base branch to beta_6_0 (can be done via PR settings)
2. Merge to beta_6_0
3. Tag security release
4. Deploy to staging

All technical reviews are complete. Only awaiting base branch correction from maintainers.
