+1 Katana Evolution Updates Hub

+1 Katana Evolution launched on Roblox on 11 June 2026 and is still receiving updates as of September 2026. Gatto vs Denis does not publish a numbered patch-note feed we can scrape. There is no public Trello of patch IDs. This hub is honest about that. We reconstruct what changed from the in-game HUD, the official group, Discord chatter that matches the HUD, and the Roblox experience update timestamp. We do not invent v1.4.2-style labels to look official.

When a month has enough verified movement to stand as its own page, it gets a child article. Right now that child is the September 2026 update. Use this hub to learn how we source notes, then open the month page for the live codes, the last Roblox bump around 4–6 September 2026, and the group asking for katana ideas.

How to read a reconstructed note

A line on this wiki is a patch note only if at least one of these is true:

• The HUD now shows a number, button, or rarity that it did not show before (recommended damage, rebirth, hatch odds, codes icon).
• The Gatto vs Denis group posted it. That community is also the join gate for codes.
• The Roblox experience page shows a fresh updated timestamp.
• Discord repeats the same fact and it matches the HUD, not a rumor screenshot with no UI.

A line is not a patch note if it is a fan name for a blade, a guessed Secret drop table beyond the ~0.20 percent hatch rate, or a numbered ID nobody printed. Descriptive katana names (bamboo, wooden, fire-inscribed, purple lightning) stay descriptive on purpose. Rank pages live under tier list, not here.

What still matters after every bump

Updates have not turned this into a co-op campaign. Servers still cap at 12 players. Progress is still individual. Rebirth still keeps katanas. Stage 2 still sits near 300 recommended damage, Stage 3 near 5,000, Stage 5 at 30,444 unless a future HUD print says otherwise. If a patch silently changes a gate, the month page will say the HUD changed. Until then, stages and the early game build remain the playbook.

Codes are part of the update beat even when the strings do not change. As of September 2026, RELEASE (10K Wins) and COOKED (50K Damage + 1 Level) still work after you join the group and use the X icon. A patch that expires a code will show up here and on the rewards list the same day we can verify the fail. Do not treat a YouTube thumbnail as an expiry date.

Where new content usually lands

• New katana: group prompt plus a new model in the shop or thumbnail. Rank it on the katana list after we see a gate match, not the day someone comments an idea.
• New evolution look: purple bar completes into a different outfit. How to evolve and the evolution list take the screenshot. This hub only records that the bar still exists.
• New pet or egg: hatch UI rarity colors. Odds we can stand behind stay at Common/Uncommon/Rare ~40 percent, Epic ~50 percent, Legendary ~10 percent, Secret ~0.20 percent until the egg screen prints something else.
• Scripts and tools: not a Roblox patch. If a farm script breaks after an update, that is a scripts hub problem, not a reason to invent a patch ID.

Follow Discord and the group if you want the raw posts before we write a month page. Follow this hub if you want those posts filtered into facts that still match the HUD. The next child page will appear when there is a new month of verifiable movement, not when we feel like numbering a patch that Gatto vs Denis never numbered.
