Breaking changes

• Faro app writes now reject spec.settings.geolocationLevel: region.
  Change it to subdivision in saved manifests before you upgrade.
  This affects gcx frontend apps writes and resource pushes. Before this
  release, gcx ignored Faro app settings on writes, so region never took
  effect. Faro settings now reach the API. (#​1444)
• gcx datasources loki labels and gcx logs labels now reject stray
  positional arguments. They also reject an explicit empty --query or
  --label. Omit these flags for an unscoped label list. Give each flag
  a nonempty value when you use it. (#​1325)

New commands and improvements

• Add gcx signup to create a Grafana Cloud account and save its first
  connection. Complete account setup in the browser. If the connection
  fails after signup, finish it with gcx login. (#​1383)
• Let gcx login --cloud --oauth open the stack chooser when no server
  is set. Browser cancellation now exits with code 5. On macOS, the
  terminal watcher uses its own device, so SSH paste works. (#​1383)
• Add gcx docs commands to search and read Grafana product docs.
  (#​1234)
• Add gcx alert routing-trees commands to manage native alert routing
  trees. (#​1472)
• Add experimental gcx profiles query-anomalies and
  gcx datasources pyroscope query-anomalies commands. Their flags and
  output may change. (#​1435)
• Add --query to scope Loki label and value lists. (#​1325)
• Add --dry-run to Synthetic Monitoring check create and update.
  (#​1429)
• Add an experimental Go sandbox module that runs gcx as WebAssembly.
  Reduce its build size and startup time. (#​1440)
• Keep resource manager identity stable across gcx upgrades. Resolve
  resource selectors with dotted API groups. (#​1537, #​1441)
• Correct Faro app settings writes. Preserve labels and mobile
  classification on create. Report truncated lists and accept app names
  in get. (#​1444, #​1390, #​1445)
• Read service map metadata correctly. Fix the SLO server interval
  example. Scope k6 load tests to the selected project. (#​1457, #​1452,
  #​1450)
• Name missing permissions in Faro proxy errors. Show native alert rule
  selectors in help. Recover after concurrent config writes. (#​1518,
  #​1458, #​1485)
• Detect Codex, Gemini, and other agent hosts. Let
  GCX_AGENT_SPILL_BYTES=0 disable output spilling. (#​1461, #​1439)
• Update docs, security reporting guidance, and on-call command
  discovery. (#​1520, #​1206, #​1305)
