What's new in RefleK's

0.10.0September 12, 2026

Languages & Custom Themes

RefleK's now speaks six languages, ships a fully editable Custom theme, detects your Steam install and account automatically, and adds smoother animated charts and stats.

New Features

  • ●Six interface languages: English, Dutch, Spanish, Simplified Chinese, Japanese, and Russian — switch anytime in Settings → Appearance
  • ●First launch follows your system language, and your choice is remembered from then on
  • ●New Custom theme: fully customize colors, fonts, spacing, and more by editing a user stylesheet, with buttons to open the file or regenerate the default template
  • ●Automatic Steam detection: RefleK's now finds your Steam install folder and signed-in account on its own, prefilling the Steam ID and persona name

Improvements

  • ●Charts and stat numbers now animate into view, with numbers counting up — animations respect the operating system's reduced-motion setting
  • ●Benchmark tables can be dragged horizontally to scroll
  • ●Benchmark progress fetches are deduplicated and retried, so rankings update more reliably
  • ●Scenario score fetch errors now explain what went wrong and how to recover
  • ●Screen capture timing stays aligned with real time for more accurate replay playback
  • ●The recommendation column is centered and no longer wraps

Bug Fixes

  • ●Fixed the benchmark scenario history dialog not using the available height, so its score chart is larger and loading states are centered
  • ●Fixed out-of-date scenario score responses updating a dialog that had already closed or reloaded

Changes

  • ●Removed the Darker theme — Dark, Light, and Custom remain, and existing Darker selections fall back to Dark
0.9.6August 12, 2026

UI Scale & Deep-Link Fixes

A new interface scale setting (60%–150%), a cleaner recommendation column with an inline legend, and more reliable Steam deep-links for launching scenarios and playlists.

New Features

  • ●New Scale setting (60%–150%) adjusts the entire interface size for large or small screens
  • ●Recommendation column now includes an info tooltip explaining every indicator

Improvements

  • ●Steam deep-links now properly percent-encode scenario names, modes, and sharecodes so special characters no longer break launching
  • ●UI spacing and sizing converted to rem units so the scale setting applies consistently across the app

Bug Fixes

  • ●Fixed playlist link errors in the benchmark detail page and overview widget being silently swallowed
0.9.5August 8, 2026

Replay Cleanup & Retention

Take control of your replay storage with automatic cleanup: set an age limit, a storage cap, or both, and let RefleK's tidy up old replays for you — at startup and as new replays are created.

New Features

  • ●Automatic replay cleanup with optional age limit (1 day to 1 month) and storage cap (1 GB to 25 GB), or unlimited
  • ●Cleanup runs at startup, when replay settings change, and after new replays finish processing
0.9.4August 5, 2026

Replay Export & Capture Health

Export replays anywhere, watch screen capture health with automatic recovery, and a faster run history — plus the usual reliability fixes.

New Features

  • ●Export replays: save any recorded run replay to a folder of your choice from the replay player
  • ●Replay status is now shown in the history inspector and updates the moment a replay finishes processing instead of polling
  • ●Live screen capture health in Settings with automatic recovery from failures like a lost display or a crashed FFmpeg process

Improvements

  • ●Changing capture resolution or FPS while the game is running now applies immediately by rotating the capture session
  • ●Run history loads faster and shows more runs by default (180 days or 2500 runs)
  • ●Capture keeps a constant frame rate even on a static screen, so replay timing stays accurate
  • ●Abandoned update downloads and interrupted capture sessions are cleaned up on the next launch

Bug Fixes

  • ●Fixed capture sessions not recovering after an FFmpeg crash or display loss
  • ●Fixed replays being lost when capture stopped shortly after a run ended — the trim now falls back to the full run window
  • ●Fixed runs ingested late being matched to the wrong capture session, which could lose their replay
0.9.3August 2, 2026

Update Reliability Fixes

A patch that makes in-app updates more reliable: the installer now finds the previous installation on its own, so upgrades from older versions replace the right install instead of leaving a broken one behind.

Bug Fixes

  • ●Fixed in-app updates from 0.8.3 and earlier not replacing the installation that launched the update — the installer now recovers the previous install directory from the registry
  • ●Fixed updates failing or aborting while the old app was still shutting down: the installer now stops the running app without killing itself and replaces the files in place instead of wiping the install folder
0.9.2August 2, 2026

Elevated Launch & Autostart Fixes

A patch that makes startup more reliable: the app now drops installer elevation before launch, "Start with KovaaK's" stays in sync with the installed executable, and the window no longer steals focus from KovaaK's.

Improvements

  • ●The app now relaunches itself with normal privileges when started elevated (e.g. from the installer), so an elevated instance can no longer interfere with an already running copy
  • ●"Start with KovaaK's" is now kept in sync with the installed executable: the installer re-registers it after updates and removes it when uninstalling
  • ●RefleK's no longer steals focus from KovaaK's when it appears while the game is running

Bug Fixes

  • ●Fixed a stale autostart entry launching a hidden instance even after "Start with KovaaK's" is turned off — the window now shows instead of leaving an invisible background process
0.9.1August 1, 2026

Update & Autostart Fixes

A small patch that makes updates more reliable: the installer now performs a clean install, leftover files from older versions are removed, and "Start with KovaaK's" keeps working after the app rename.

Improvements

  • ●The installer now fully replaces the previous installation, so files from older versions can no longer linger after updates

Bug Fixes

  • ●Fixed "Start with KovaaK's" breaking after updates by re-pointing the autostart entry at the current executable
  • ●Removed the leftover legacy executable that could survive updates and be launched by stale autostart entries
0.9.0August 1, 2026
