๐Ÿ› Bug Fixes

  • Fixed a bug in learning problem localization where a failed code-block replacement would incorrectly substitute the entire description string instead of preserving the original match.
  • Fixed malformed NUL/control-character delimiters in the localization template by replacing them with explicit \u0000 escape sequences, preventing encoding issues across editors and CI.
  • Fixed the bug-report API path in the fetch layer so submitting a report no longer creates or persists a guest session token for already-authenticated users.
  • Java wrapper visibility timeout handling was improved to prevent stale execution states from blocking subsequent submissions.
  • CI/CD automation was hardened: release workflow now requires an explicit PR body checkbox before generating the update page entry, preventing accidental entries on routine merges.

  • New practice-guide landing pages were added for coding interview prep, language-specific practice, gamified practice, and beginner-friendly entry points.
  • Routing and browser-only component behavior were tightened so prerendered pages, ads, storage reads, and session helpers behave more safely during static generation.

๐Ÿ› Important Fixes & Release Hardening
