Most discussed new issues
- [BUG] 2.1.243 Segmentation fault
- [BUG] v2.1.242 segfaults on every launch (even `--version`) — interposed mimalloc `free` has no NULL check, glibc `newlocale` calls `free(NULL)` pre-main; v2.1.241 unaffected
- [BUG] Opus 4.8 and 5.0 is consistently broken and unusable.
- [BUG] Code tab writes UI render metadata (start_timestamp/stop_timestamp/flags) into transcript JSONL, causing unrecoverable API 400 that recurs after full sanitization
- [BUG] Claude Code 2.1.243 immediately segfaults on Arch Linux x86_64
- Segfault regression at 2.1.242 on glibc 2.44 (Arch) — distinct from closed #62747
- [BUG] claude segfaults, so does install.sh
- [P0 CRITICAL] Repeated false-positive “cybersecurity topic” blocks on legitimate commercial ops work involving Grokbot / xAI (Opus 4.7)
- [BUG] Segmentation fault (SIGSEGV) on install and startup — CachyOS Linux
- [BUG] Native installer (2.1.243) segfaults in newlocale/free during startup on glibc 2.44 (CachyOS)
- Windows: app window is always-on-top with no way to disable it
- [BUG] 2.1.243 segfaults on startup - glibc 2.44 / Bun runtime crash in newlocale()
- Claude Code 2.1.243 segfaults on launch (CachyOS/glibc 2.44) — 2.1.241 unaffected
- Slash-command picker does not open unless "/" is the first character of the composer, but the command still runs on submit
- Deterministic SIGSEGV on claude CLI startup (free/__newlocale/pthread_once)
- Backgrounded Bash commands can report a false "exit code 0" completion when the command actually failed
- Windows desktop: stealth update leaves orphaned processes holding old AppX container; new version unlaunchable (0x80070020) until reboot
- [BUG] Claude Code desktop app (Windows MSIX): idle stealth update quits app, child process survives, register fails 0x80073D02, app unlaunchable until hidden process is killed
- [Bug] Version 2.1.243 fails to launch on multiple machines, autoupdate causes regression
- [BUG] Desktop app creates duplicate project directories for UNC cwd (trailing-separator normalization), causing daily chat-history loss
