v3.1.1 Release

PriconneReALLTL Installer v3.1.1 — a patch release fixing a v3.1.0 defect in the Vietnamese install path, found by a closeout audit. If you use the Vietnamese source with the AutoUpdater shortcut, please update.

Fixed

• The AutoUpdater shortcut no longer breaks a Vietnamese install. v3.1.0's auto-update path (the "update + play" shortcut) did not chain the modloader engine base for a text-only source like Vietnamese, so a Vietnamese-only install updated this way would have its BepInEx engine removed and never restored — leaving the game unmodded. The auto-update path now stages and re-applies the ImaterialC engine base before the text layer, with the same SHA-256 verify-before-touch ordering as the main-window operations. (The main-window Install / Update / Reinstall were already correct in v3.1.0 and are unaffected.)
• Logging hardening (defense-in-depth) — the logger's own fallback diagnostic messages now also pass through the credential redactor. No token was ever exposed by these paths; this closes the gap structurally.

Changed

• The installer's file-properties description now reads (EN/TH/VN).
• Corrected the wording (from v3.1.0) describing the Vietnamese fixup plugins — they load because the ImaterialC engine base ships them active, not via a per-source toggle.

Compatibility

• Windows 10 (64-bit) / 11. Requires Princess Connect! Re:Dive installed via DMM Game Player. Runs on .NET Framework 4.8 (preinstalled on Windows 10 1903+ and Windows 11).
• Translation sources: English (ImaterialC/PriconneRe-TL), ไทย (PeterkleCG/PriconneTH), Tiếng Việt (NTP335/PriconneRe-VN); modloader pinned to ImaterialC.

Upgrade Notes

• Drop-in over v3.1.0 — settings, token, and your installed patch are unaffected.
• Vietnamese users who set up an AutoUpdater shortcut on v3.1.0: after updating to v3.1.1, run Reinstall once in the app to restore the engine base if your install was already affected.

Known Issues

• A Vietnamese install shows the game's images untranslated (Japanese) — the English image pack lives under the en language folder and does not load under Language=vi. Text is fully translated; image support is a possible future enhancement.

v3.1.0 Release

PriconneReALLTL Installer v3.1.0 — Tiếng Việt (Vietnamese) joins English and ไทย as a third translation source, with the install machinery extended for text-only patches. Xin chào các bạn người Việt! 🇻🇳

Added

• Vietnamese translation source — NTP335/PriconneRe-VN is now selectable from the main screen alongside English and ไทย. Per its author's request, a quality notice is shown when you select it ("Đây là bản dịch bằng Gemini AI — sẽ có vài lỗi nhỏ và cách xưng hô chưa đúng. Cân nhắc trước khi tải."); declining keeps your previous source. Coordinated with the author in NTP335/PriconneRe-VN#1.
• Engine-base chaining for text-only sources — the VN patch ships only its translation text (~15 MB), so installing it automatically fetches the ImaterialC modloader engine (~330 MB) first as the base layer, then applies the Vietnamese text on top. Both downloads are SHA-256-verified before anything touches your install; the engine zip is cached and shared with a plain English install; uninstalling Vietnamese removes the base too unless English still owns it (ref-counted, as always).
• Per-source notice dialog — translation sources can declare a one-line disclaimer that appears before your selection persists.
• README in Vietnamese — README.vi.md.

Fixed

• Text-only sources now get the right Language= — a source whose zip ships no AutoTranslatorConfig.ini (VN) falls back to its own language code; previously the setting would have stayed on the engine base's en and the translation would never load.
• A failed engine-base extract can no longer report success — the extract-success flag is sticky across the chained base + text extractions, and the text layer is skipped when the base failed (the operation reports as failed; Reinstall repairs it).
• The translation-source menu no longer leaks — the transient context menu is disposed after it closes.
• VN's fixup plugins — per the author's own test, the Vietnamese text needs the English fixup DLLs (PriconneTLFixup / PriconneSkillTLFixup) for correct font sizing, so VN enables them (the ไทย-only fixup stays shelved).

Changed

• Ignore-list defaults are now language-agnostic — the default protected rule files (_Substitutions / _Preprocessors / _Postprocessors) use a * language glob out of the box, matching what the startup migration already produced for existing installs; a fresh install is protected under vi/th from the first run, and "reset to defaults" no longer briefly reverts to the en-only list.
• Source files with non-ASCII literals carry an explicit UTF-8 BOM instead of relying on compiler encoding detection.

Compatibility

• Windows 10 (64-bit) / 11. Requires Princess Connect! Re:Dive installed via DMM Game Player. Runs on .NET Framework 4.8 (preinstalled on Windows 10 1903+ and Windows 11).
• Translation sources: English (ImaterialC/PriconneRe-TL), ไทย (PeterkleCG/PriconneTH), Tiếng Việt (NTP335/PriconneRe-VN); modloader pinned to ImaterialC.

Upgrade Notes

• Drop-in over v3.0.x — settings, token, and your installed patch are unaffected.
• The Vietnamese source is new in this release — switching to it walks you through the author's quality notice, then installs the engine base + the VN text in one operation.

Known Issues

• A Vietnamese install shows the game's images untranslated (Japanese) — the English image pack lives under the en language folder and does not load under Language=vi. Text is fully translated; image support is a possible future enhancement.

v3.0.7 Release

PriconneReALLTL Installer v3.0.7 — fixes the v3.0.6 title-bar regression and rolls in menu icons + resumable downloads. A healthy install behaves the same.

Added

• Menu icons — the Settings and Help menus now show a small icon beside each item, rendered from a Windows system icon font (no new artwork, no extra download).
• Resumable patch downloads — if a download is interrupted (a slow or flaky connection), running it again resumes from where it stopped instead of re-downloading the ~330 MB from zero, with automatic retry and backoff. The file is still SHA-256-verified before anything touches your install, so an incomplete or mismatched download can never overwrite a working patch.

Fixed

• The blue Windows title bar is gone — v3.0.5/v3.0.6 accidentally resurfaced the OS caption on every window (and clipped the bottom status row when logs were collapsed). All windows are borderless custom-chrome again.
• Minimizing from the taskbar works again.
• Cleaner log messages — no literal \n in the "modloader outdated" notice, no stray $ in the export/import lines, a routine "found config file(s)" message no longer shows as a red error, and consistent international-English wording (including an "occurred" spelling fix).

Changed

• The bug-report template is now a guided form — dropdowns for translation source / operation / launcher plus required fields.
• CONTRIBUTING's coding-conventions now document the project's real standards (logging style, install-safety invariants, the borderless-form rule).

Security

• Logged file paths now mask your Windows username (%USERPROFILE%) — less personal information ends up in a log you might paste into an issue. (The GitHub token was already redacted.)

Compatibility

• Windows 10 (64-bit) / 11. Requires Princess Connect! Re:Dive installed via DMM Game Player. Runs on .NET Framework 4.8 (preinstalled on Windows 10 1903+ and Windows 11).
• Translation sources: English (ImaterialC/PriconneRe-TL), ไทย (PeterkleCG/PriconneTH); modloader pinned to ImaterialC.

v3.0.6 Release

PriconneReALLTL Installer v3.0.6 — a small follow-up to v3.0.5: a second review pass over the v3.0.5 changes (no regressions found) plus a re-sweep of corners the first audit covered lightly. A healthy install behaves the same.

Fixed

• Completed the COM-handle cleanup from v3.0.5 — the "Create AutoUpdater shortcut" action now releases its shell objects like the other shortcut operations.
• Folder-boundary check — "is this file inside the game folder?" (used when adding an ignore-list entry) now respects a folder boundary, so a sibling folder with a similar name is no longer mistaken for being inside the game folder.
• Modloader version parsing — the installed-modloader version reads correctly when a component has three digits (e.g. 6.0.100).
• Internal hardening — the uninstall manifest's staged state is reset at the start of each removal (defensive), and a dead no-op handler was removed.

v3.0.5 Release

PriconneReALLTL Installer v3.0.5 — a large correctness, safety, and security release from a full-codebase deep audit layered on top of the v3.0.4 test campaign. Most fixes matter on the unhappy paths (a locked file, a running instance, a corrupt manifest, a cold token) and several are leaks/races that manual testing can't surface. A healthy install behaves the same.

Highlights

• A locked translation file can no longer break a reinstall/uninstall. The installer now checks that every tracked file is unlocked first and aborts cleanly — leaving your install 100% intact — if the game, antivirus, Windows Search, a cloud-sync app, or an editor is holding a file.
• The installer/uninstaller detects a running instance and offers to close it first, instead of failing on the locked program.
• Wrapped launcher shortcuts get a clean lifecycle — un-wrapped automatically when you uninstall the program (so they revert to plain game-launchers), Desktop "… (TL update)" copies removed when you un-manage them, and moved/deleted ones flagged "(missing)".
• New: Settings → "Reclaim Space in Game Folder" — frees disk by removing BepInEx's regenerable log + assembly cache and pruning leftover empty folders; never touches your patch, settings, or any user files.
• A pile of crash-safety, resource-leak, and UI-responsiveness fixes from the audit, plus consistent window titles and UI text.

Security

• The optional GitHub token is no longer loaded into a UI field, no longer attached to release-asset downloads (closing a path where a redirect could forward it off-GitHub), and validated off the UI thread.
• Settings import is hardened against XXE; error dialogs no longer print stack traces.
• The honest-disclosure docs now acknowledge the inherited UI art as a known gap to re-skin.

v3.0.4 Release

PriconneReALLTL Installer v3.0.4 — a small security + UI-polish release. Everything from v3.0.0–v3.0.3 still applies; a healthy install behaves the same.

Security

• Zip extraction now writes to the path it just validated. The zip-slip (path-traversal) guard already confined every entry to the game folder — the extraction step now writes to that same guard-checked path instead of re-deriving it from the (untrusted) entry name. Resolves the CodeQL cs/zipslip alert; no behavioral change for a healthy patch.

Changed

• Language labels finalized — the compact "TL Source" label shows the ISO code (EN / TH); the source picker shows each language's native full name (English / ไทย). Internal manifest keys are unchanged, so existing installs are unaffected.

v3.0.3 Release

PriconneReALLTL Installer v3.0.3 — a small security + robustness release. Everything from v3.0.0–v3.0.2 still applies; a healthy install behaves the same.

Fixes

• Shortcut wrapping is no longer silent + handles protected folders — "Set / Modify launch shortcut" now always tells you the result, and if a shortcut is in a write-protected folder (e.g. the All-Users Start Menu under C:\ProgramData\…) it wraps a copy on your Desktop ("… (TL update)") instead of doing nothing.
• Self-update can't crash the app — the installer self-update flow is guarded against unhandled exceptions.

Security

• The validated GitHub token is cached by SHA-256 hash, never held as plaintext in a long-lived field.
• Diagnostic logging no longer uses Console.WriteLine (it bypassed the log redactor); debug traces are compiled out of release builds.
• CodeQL code scanning is now enabled (C# static analysis on every push / PR), alongside Dependabot.

v3.0.2 Release

PriconneReALLTL Installer v3.0.2 — a hardening release from a full-project security + correctness review. Everything from v3.0.0 / v3.0.1 still applies; this fixes more defects on the unhappy paths (multi-language uninstall, a wrong system clock, interrupted state). A healthy install behaves the same.

Fixes

• Per-language "Remove Ignored" — uninstalling one source's ignored data no longer deletes another installed language's user-edited XUnity files (uninstalling English no longer touches ไทย's substitutions / pre/post-processors).
• Logs live in the app data folder (%LOCALAPPDATA%\PriconneReALLTLInstaller), not the install folder — a Windows uninstall leaves no stray log behind.
• "Check for Updates Now" logs its result and resets the status bar (no stuck "Checking…").
• Wrong-clock warning — if your system clock is off by more than a day vs GitHub's time, the app warns once to correct it (a wrong clock breaks update checks and can stop translations from showing — see Known Issues).
• Per-flow version-cache bypass (AsyncLocal) — no more stale-version flash when switching source and checking for updates together.
• Safe manifest-update fallback on uninstall — a failed manifest write no longer risks a later double-removal of shared files.
• Validated wrapped-launch target — must be an existing .exe/.lnk, otherwise it falls back to DMM Game Player.
• Hardened internals — the release-tree fallback is awaited (no blocking-on-async); the release asset list is null-guarded; the self-update download won't stamp a .exe as a zip; XXE-safe settings import.

Changed

• Old releases keep their SHA256SUMS.txt (only the heavy installer binaries are stripped) → an older build stays verifiable.
• Language labels: full names use each language's native form (English / ไทย), abbreviations use ISO codes (EN / TH).

Upgrade Notes

• Drop-in over v3.0.0 / v3.0.1 — settings, token, and your installed patch are unaffected.

Known Issues

• If translations don't appear in-game and the patch is installed, check that your Windows date/time is correct — the game itself can misbehave on a wrong clock (the app now warns about large skew).
• Installing/uninstalling a source manually (by zip) is invisible to the tracked-install manifest — install via the app for a clean per-source uninstall.

v3.0.1 Release

PriconneReALLTL Installer v3.0.1 — a bug-fix release hardening install integrity, version detection, and crash-safety. Everything from v3.0.0 still applies; this fixes defects found in a full-project review. A healthy install behaves the same — these fixes matter on the unhappy paths (interrupted downloads, a wrong system clock, double-digit version numbers, failed operations).

Fixes

• Numeric version comparison — 2.1.10 is now correctly newer than 2.1.9 (and 3.0.10 newer than 3.0.9). Previously versions were compared letter-by-letter, so once a segment reached two digits a genuinely newer patch or installer update could be silently not offered.
• Interrupted downloads can't corrupt a working install — the ~330 MB patch zip downloads to a temporary file and is promoted to the reusable cache only after it passes verification, so a partial or aborted download is never reused and extracted over your game. The rate-limit cache fallback now also restores the expected SHA-256 so the integrity check stays correct.
• No launch after a failed operation — "Launch Game" starts the game only when the install/uninstall actually succeeded, so a half-patched install can't auto-launch (and the 5-second auto-exit can't hide the error).
• Path-guarded config/ignored removal — "Remove Config" / "Remove Ignored Patch Files" deletions are confined to the game folder, matching the existing extraction and main-removal guards.
• A backward system clock no longer freezes update checks — if your PC clock was set behind the time a check was cached (a dead CMOS battery, a manual change), the app used to treat the cached result as permanently fresh and stop checking; it now re-fetches when the cached age is out of range. (Separately: if translations don't appear in-game, make sure your system date/time is correct — the game itself can misbehave on a wrong clock.)
• Crash-safety — a download with no Content-Length no longer throws on the progress bar (clamped to 0–100%); a malformed DMM game-path entry is rejected instead of causing a null-path crash; the "open game folder" command quotes the path so folders with spaces open correctly.

Upgrade Notes

• Drop-in over v3.0.0 — settings, token, and your installed patch are unaffected. No reinstall of the translation patch is needed.

Known Issues

• Installing/uninstalling a source manually (by zip) is invisible to the app's tracked-install manifest, so a manual source can't be cleanly uninstalled by the app — install via the app for a clean per-source uninstall. (A 2-layer translation/modloader uninstall is planned.)

v3.0.0 Release

PriconneReALLTL Installer v3.0.0 — the first public release of the rebranded, multi-source successor to PriconneReTL-Installer. "ALL TL" because it now installs any supported translation patch, not just one. This is a new product line with its own identity (name, signing key, self-update), forked with thanks from tynave/PriconneReTL-Installer under MIT.

Highlights & Fixes

• Multiple translation sources, user-selectable: switch between English (ImaterialC/PriconneRe-TL) and ไทย (PeterkleCG/PriconneTH) right from the main window. Installed-version detection, the modloader pin, and AutoTranslatorConfig.ini (language + texture list) all follow the selected source automatically.
• Per-user installer (no admin): a proper Inno Setup installer alongside the portable exe. It adds a Start Menu shortcut and a clean uninstall entry that also clears the app's local cache/settings. Self-update still works because it installs under your user profile.
• Safer installs: the downloaded patch zip is SHA-256 verified against GitHub's published digest before anything is touched, so a corrupt or interrupted download can never half-overwrite a working install.
• Faster repeats: the ~330 MB patch zip is cached locally, so reinstalling or switching back to a source you already downloaded skips the re-download.
• Ref-counted uninstall: with both EN and TH installed, uninstalling one leaves the other (and the shared modloader) fully working; uninstalling the last one removes everything.
• Shortcut-wrapped launching: wrap an existing launcher/account shortcut so launching it updates the patch first, then starts your game.
• Weekly update check: the installer self-update check now caches its result for 7 days (it's a mature tool, not a browser). Patch/modloader checks stay frequent. A new Check for Updates Now menu action runs an on-demand live check any time.
• Quieter, more responsive UI: every GitHub call runs off the UI thread, so a slow or rate-limited response never freezes the window. Installed files keep their real source-build dates.
• Runs on .NET Framework 4.8 (up from 4.7.2) — preinstalled on Windows 10 1903+/11, so there's nothing extra to install.
• Own neutral branding — the installer now ships its own language-neutral "Priconne Re:ALLTL" logo instead of borrowing one translation source's artwork, so it stays fair to every supported language.

Security & hardening

• GitHub token byte buffers are zeroed (Array.Clear) right after use (DPAPI, CurrentUser scope); logs neutralize CR/LF/tab to prevent log forging (OWASP A09) on top of fail-closed token redaction; Dependabot alerts + weekly dependency / GitHub-Actions update PRs are enabled.

Build & Distribution

• Builds run entirely in GitHub Actions on every version tag. Local builds are not distributed.
• The latest release ships the portable exe, the per-user installer, and SHA256SUMS.txt. Older releases keep only their source code — their installer/portable assets are removed automatically so nobody downloads a stale build.

Compatibility

• Windows 10 / 11.
• Requires Princess Connect! Re:Dive installed via DMM Game Player.
• A GitHub token is optional — version checks are cached, so the app works fine unauthenticated.

Upgrade Notes

• Coming from the old PriconneReTL-Installer? This is a separate product with its own identity, so install it fresh. Your game's translation patch is detected in place — no need to reinstall the patch itself.
