📝 WalkthroughWalkthroughVersion 0.64.9 is released with two fixes: an unbounded Git repository search prevention to avoid memory growth, and restoring the default Browser Memory Saver setting. The version number is bumped consistently across all Xcode build configurations from 0.64.8 to 0.64.9, and release notes are published in both the main changelog and the web changelog media record.

Greptile SummaryThis is a hotfix release bumping the version to 0.64.9. It adds changelog entries for two fixes — stopping the unbounded Git repository root walk that caused an OOM on non-Git workspaces, and restoring the Browser Memory Saver default — alongside the corresponding Xcode project version bumps.
Confidence Score: 4/5Safe to merge; all three files contain routine hotfix bookkeeping with no production logic changes. The Xcode version bumps and CHANGELOG entry are mechanical and consistent. The new changelog-media entry adds English-only copy to a locale-aware page, continuing a pre-existing gap in the file — the actual fix code lives in separate PRs already merged. web/app/[locale]/docs/changelog/changelog-media.ts — new feature description strings are not routed through next-intl, same as existing entries but worth tracking as the debt grows.

There was a problem hiding this comment.
title, feature title, and feature description) are rendered directly as JSX in the [locale]-prefixed changelog page (FeatureList and the version-heading div) without going through next-intl. The page serves 20 locales (en, ja, zh-CN, zh-TW, ko, de, es, fr, it, da, pl, ru, bs, ar, no, pt-BR, th, tr, km, uk per web/i18n/routing.ts), so non-English visitors see English copy. The full-i18n rule flags "changelog copy… not consumed from next-intl… and represented across all locales in web/messages/." All prior changelogMedia entries share this debt, but the PR introduces new instances of it.

Summary by cubic
Hotfix to stop the v0.64.8 memory leak that caused RSS to spike in non‑Git workspaces. We now stop Git repo discovery at the filesystem root and turn Browser Memory Saver back on by default to prevent runaway memory and OOM.
