Stellar Affinity Patch Notes

Patch notes are how we know when to refresh the tier list, team builds, and divine artifacts guidance. This page tracks themes of each Stellar Affinity update on EROLABS rather than pasting raw legal changelogs. Official client text always wins on conflict.

The game launched 29 July 2026. Early patches often mix hotfixes for mail delivery, redeem UI, and tutorial locks with the first balance nudges to idle income or stage modifiers. If your launch rewards mail looks missing after an update, reclaim before you theorycraft.

v1.15 Eleanor and QoL features

The September 7, 2026 update brought the Eleanor limited recruit (running through September 28, 2026 19:59 UTC-7) alongside several quality-of-life improvements:

• To-Do List — opens from the upper-left of the main screen and shows rotation periods and mission progress for Ascension, Proving Grounds, Cataclysm Survivor, Boss Blitz, and Operation: Shadow Siege
• System Recommendation on Potential Presets — automatically suggests presets based on your Main Trekker’s element
• System Preset on the Trekker Potential screen — shows recommended builds for each character
• Operation: Shadow Siege — Siege Level buffs now fold into estimated Hunter Medals on Co-op Hunt and Pause screens
• Cataclysm Survivor — now permanent content (Auth Level 11+) rewarding Stellanite Dust, Defender’s Medal, and Sprout Tickets weekly

September 21 triple event

Early August updates: verify the client version

After early-August hotfixes and store pushes, captains should confirm the client version / build string inside Settings (or the store listing) before filing bugs or blaming a “soft wipe.” Mismatched APKs on emulators are a common false alarm — one device on the old package, another on the new one, same EROLABS login looking “broken.”

When you report a bug to platform support or a partner store:

1. Note the on-screen client version after the update finishes.
2. Include the Android package id used on many EROLABS / emulator listings: com.himefun.stellaraffinity.erolabs.
3. Confirm you are bound to a real identity via account & bind — guest sessions lose more “progress” than balance patches ever wipe.
4. If install or update loops, follow download & PC before reinstalling over a dirty cache.

Wrong package forks and unbound guests create tickets that look like patch regressions. Version + package + bind status is the minimum triage kit.

What we watch each patch

• New characters and rate-ups (update roster mental model)
• Bond / Cumpanion or energy conversion tweaks (Hime Bonds, Cumpanions, artifacts & energy)
• Artifact and module balance
• Redeem / mail bug fixes (re-check active codes and how to redeem)
• Store or APK update requirements (download & PC, account & bind)
• Idle rate or bullet-hell stage modifier changes (combat & idle)

Post-update checklist

1. Install cleanly; verify client version; if the client loops, follow download & PC.
2. Confirm bind / login on account & bind before spending compensation.
3. Open mailbox — claim compensation, delayed fragment gifts, or CBT return mail.
4. Re-check active codes and tick attempts in the codes tracker.
5. Test your story team on a hard node from the planet walkthrough.
6. Adjust progression if material costs or caps changed.
7. Skim current events for missions that appeared with the build.

How patches interact with launch economy

Early patches sometimes clarify whether server gifts (5000 碎星), login pull campaigns (200), or carnival rows grant late. Do not paste those campaign names into Redeem — mail ≠ code box. Newbie targeted recruit and story free-core → 6★ paths may also receive UI fixes; re-read gacha & summon if a button moved.

When the meta actually moved

Only reshuffle binders when notes mention skill multipliers, artifact families, or energy conversion. Cosmetic patches and shop SKUs do not justify melting a built carry. Use best teams as the recipe book and builds hub as the upgrade plan after a real combat change.

If a patch breaks installs, prioritize recovery before theorycrafting. A perfect tier list cannot help a client that will not boot.

Reading notes like a captain, not a lawyer

Skim for verbs that change power: adjusted, reduced, increased, fixed, reset, migrated. Ignore marketing adjectives. If a note says affection missions were “optimized,” test one gift cycle on your carry before assuming income doubled. If a note says mail delivery was fixed, open the mailbox even if you think you claimed everything during the 29 July 2026 rush.

Keep a tiny re-test script:

1. One story node that used to be comfortable.
2. One boss check from Template C on best teams.
3. One idle harvest comparison (screenshot before/after if numbers are visible).
4. One Redeem attempt if compensation codes were announced (active codes).
5. One Settings glance to confirm the client version matches the patch you think you installed.

Wiki pages to reopen after each theme

Patch theme	Reopen
New girl / rate-up	Tier list, roster, gacha & summon, Eleanor guide
Bond / energy	Hime Bonds, Cumpanions, artifacts & energy
Modules	Divine artifacts, team builds
Economy / shops	Currencies, current events
Client / login	Download & PC, account & bind, launch rewards if mail broke

Do not spiral on rumor patches

Datamined numbers without a live client build are entertainment, not marching orders. Wait for the forced update, then spend. Panic melting artifacts because a screenshot alleged a nerf is how accounts lose weeks of progression. When in doubt, clear beginner week-style dailies (or daily routine after carnival ends) and reassess tomorrow.
