The game procedurally generates dungeon layouts from a repository's commit SHA using Binary Space Partitioning (BSP), meaning every codebase produces a unique dungeon that evolves with each commit. The post explains how BSP works for dungeon generation, how the /delegate command in Copilot CLI was used to asynchronously build features via pull requests, and how to install and play the extension. A 'danger mode' pre-commit hook that deletes unsaved work if you lose the game is included as a (strongly discouraged) bonus. 70 2. 2 [](https://daily.dev/posts/from-latency-to-instant-modernizing-github-issues-navigation-performance-t1jb6lu6h "From latency to instant: Modernizing GitHub Issues navigation performance") Article GitHub Blog · 17w From latency to instant: Modernizing GitHub Issues navigation performance The GitHub Issues team redesigned their navigation performance by building a client-side caching layer backed by IndexedDB with stale-while-revalidate semantics, a preheating strategy that proactively populates cache entries before users click, and a service worker that intercepts hard navigations to serve cached data. The result: P10 latency dropped from \~600ms to 70ms, P25 from \~800ms to 120ms, and the median from \~1200ms to 700ms. React soft navigations saw \~70% become instant after preheating, with a 96% cache-hit ratio. The post details the three navigation types (hard, Turbo, React soft), the HPC metric used for measurement, tradeoffs around controlled staleness (\~4.7% server/cache divergence), and the remaining challenges around cold-start JavaScript boot time. 14 1 3. 3 [](https://daily.dev/posts/github-copilot-individual-plans-introducing-flex-allotments-in-pro-and-pro-and-a-new-max-plan-pnbjf6b43 "GitHub Copilot individual plans: Introducing flex allotments in Pro and Pro+, and a new Max plan") Article GitHub Blog · 17w GitHub Copilot individual plans: Introducing flex allotments in Pro and Pro+, and a new Max plan GitHub is updating its individual Copilot plans starting June 1, 2026\. Pro and Pro+ plans will include a new 'flex allotment' on top of base credits, effectively increasing total included usage at no extra cost. Pro goes from $10 to $15 worth of usage, Pro+ from $39 to $70, and a new Max plan at $100/month offers $200 in total usage. Base credits are fixed 1:1 with subscription price, while flex allotments may change over time as AI model economics evolve. Code completions and next edit suggestions remain unlimited on paid plans. Existing monthly subscribers are migrated automatically on June 1. 10 [See all GitHub Blog archives](/sources/ghblog/best-of) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@graph":[{"@type":"CollectionPage","@id":"https://daily.dev/sources/ghblog/best-of/2026/05#page","url":"https://daily.dev/sources/ghblog/best-of/2026/05","name":"Best GitHub Blog Posts — May 2026","description":"The most upvoted GitHub Blog posts from May 2026, curated by the daily.dev community.","isPartOf":{"@type":"WebSite","url":"https://daily.dev"}},{"@type":"ItemList","@id":"https://daily.dev/sources/ghblog/best-of/2026/05#items","numberOfItems":3,"itemListElement":[{"@type":"ListItem","position":1,"url":"https://daily.dev/posts/dungeons-desktops-building-a-procedurally-generated-roguelike-with-github-copilot-cli-ngdmj7dg7","name":"Dungeons & Desktops: Building a procedurally generated roguelike with GitHub Copilot CLI"},{"@type":"ListItem","position":2,"url":"https://daily.dev/posts/from-latency-to-instant-modernizing-github-issues-navigation-performance-t1jb6lu6h","name":"From latency to instant: Modernizing GitHub Issues navigation performance"},{"@type":"ListItem","position":3,"url":"https://daily.dev/posts/github-copilot-individual-plans-introducing-flex-allotments-in-pro-and-pro-and-a-new-max-plan-pnbjf6b43","name":"GitHub Copilot individual plans: Introducing flex allotments in Pro and Pro+, and a new Max plan"}]},{"@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Sources","item":"https://daily.dev/sources"},{"@type":"ListItem","position":3,"name":"GitHub Blog","item":"https://daily.dev/sources/ghblog"},{"@type":"ListItem","position":4,"name":"Best of","item":"https://daily.dev/sources/ghblog/best-of"},{"@type":"ListItem","position":5,"name":"May 2026"}]}]} ```
