Sephiria patch notes

This page is a timeline of first-party Steam news relevant to the live 1.0 era. It is not a complete mirror of every engine change, and it does not rewrite developer posts into marketing fluff. When official wording is short, this page stays short rather than inventing changelists.

Use patch notes after any update before you trust older combat or inventory habits. Co-op groups should confirm everyone is discussing the same version label. Database pages on this wiki describe systems; this page describes when those systems were announced or adjusted.

Primary sources include the Steam news hub for app 2436940, the 1.0 Update post, the 1.0.21 Hotfix post, and the English RSS feed used to verify titles and dates during research on 2026-08-01.

Treat this timeline as a field-manual index into Steam news, not as a full mirror of every binary change. Short official posts stay short here. Version labels help co-op groups argue about the same build.

Sephiria’s full release date on Steam is 31 July 2026. The 1.0 Update announcement is the feature baseline for this wiki: six chapters, six weapon branches, more than 200 weapon upgrades, about 300 Artifacts, about 70 Tablets, more than 30 Potions, more than 20 costumes, 18 Hard Mode elements, twelve in-game languages, and online co-op for up to four players.

Those bullets are the launch contract against which later hotfixes should be compared. If a hotfix only tunes stability, the feature contract remains. If a future post changes a count or system rule, update the dossier and the relevant system page together—not just a single paragraph on the homepage.

Players arriving from Early Access should treat 1.0 as a new baseline rather than as a tiny content drop. The chapter count and database scales are the structural headline.

The 1.0 Update is the feature baseline: six chapters, six weapon branches, 200+ upgrades, ~300 Artifacts, ~70 Tablets, 30+ potions, 20+ costumes, 18 Hard Mode elements, twelve languages, and up-to-four online co-op. Compare later posts against that contract.

Steam news lists a 1.0.21 Hotfix in the live 1.0 window. Hotfix posts typically prioritize crash, softlock, networking, or balance micro-fixes rather than rewriting the entire feature set. Read the official post body on Steam for the authoritative bullet list; this wiki records the existence, label, and role of the hotfix in the timeline.

If you are debugging a co-op issue or a board bug, check whether your client matches the latest hotfix before assuming a strategy error. Version mismatch between friends is a common false “balance” complaint.

When summarizing hotfixes for the field manual, prefer quoting categories of change over paraphrasing numbers that might be patched again the same week.

1.0.21 is recorded as a hotfix line in the live 1.0 window. Read Steam for authoritative bullets; use this page for placement in the chronology. Confirm clients match before diagnosing “balance” in co-op. If friends report different behavior, compare build labels before rewriting strategy. Hotfix posts are short by design and should be read on Steam rather than reconstructed from memory.

Each new first-party post should add a dated timeline row, a short factual summary, and links from any system page whose rules changed. Do not leave the homepage dossier on stale counts after a deliberate content expansion.

Media for patch pages can include official trailers when they help players see the live presentation, but trailers are not changelogs. Keep the Steam news URL as the canonical text source.

This site remains unofficial. If TEAM HORAY amends a post, the Steam version wins.

Future posts should add a dated row, a factual summary, and updates to any system page whose rules changed. Trailers can illustrate presentation but never replace changelog text. TEAM HORAY’s Steam wording wins conflicts. Keep homepage dossier counts synchronized when an official post expands a system. Avoid editing one paragraph while leaving the systems ledger stale on another route.

Players consulting the editorial process notes should re-open Steam news if a fresh hotfix landed after this page’s verification date of 2026-08-01.

31 July 2026 — Sephiria 1.0 full release on Steam (AppID 2436940), accompanied by the 1.0 Update feature package described above. Same window — 1.0.21 Hotfix appears in the Steam news feed as a live maintenance post. Research capture also retained the English RSS feed titles for cross-check.

Earlier public materials include demo and Early Access trailers on first-party and store-adjacent channels. Those trailers help media orientation but are not substitutes for 1.0 feature counts.

For day-to-day play, combine this timeline with the beginner guide and systems indexes rather than reading patch text alone in isolation.

Snapshot research on 2026-08-01 retained Steam news titles and the English RSS feed for cross-check. Day-to-day play still needs beginner and database pages; patch text alone is not a tutorial.

For timeline, prefer first-party Steam wording over memory when a dispute appears after a patch.

• 2026-07-31 — 1.0 full release / 1.0 Update feature baseline
• 2026-07-31 window — 1.0.21 Hotfix listed on Steam news
• 2026-08-01 — wiki research verification pass on Steam news + RSS

Primary materials for this timeline come from the official Sephiria Steam store page and the app news hub for AppID 2436940. Read those posts for authoritative hotfix bullets and feature language before treating any fan summary as final. When a Steam post and this field manual disagree, prefer the first-party wording and then file a correction.

Use the links below to open the exact surfaces used during the 2026-08-01 research pass. Keep the version label from the latest hotfix in mind when co-op partners report different behavior on the same chapter band.

Trailers and store screenshots help orientation, but they are not changelogs. Pair this sources list with the chronology sections above when you need both a date and a system impact for Version 1.0. If TEAM HORAY edits a post after publication, refresh the Steam page before you update local notes or co-op voice calls about what changed.
