+# SpecShield CLI changelog
+
+## 3.2.0 — 2026-05-17 — Conversion fixes
+
+Three CLI changes designed to make the Cloud features (history, share URLs,
+PR checks, BDCT) visible to the 2,000+ existing CLI users who run local
+`specshield compare` but never discover what signing up unlocks.
+
+### Added
+
+- **Post-install welcome banner** — runs once after a fresh `npm install -g specshield`.
+  Briefly explains the value progression (Local → Cloud Free → Pro) and points
+  to the next command to try. Skipped automatically in CI, in non-TTY shells,
+  on update installs, and when `SPECSHIELD_NO_BANNER=1` is set.
+
+- **Contextual signup prompt after `specshield compare`** — after 3+ compares
+  per week, a soft 3-line nudge appears below the regular output:
+  ```
+  ● Track these comparisons over time:
+    specshield login   # 30-sec signup via GitHub / Google · no credit card
+    Unlocks: compare history, shareable report URLs, PR badge
+  ```
+  Throttled to once per week so it never spams. Suppressed entirely for
+  logged-in users, `--json` output, CI environments, and on opt-out. The
+  prompt copy escalates at 10 and 25 compares per window.
+
+- **`specshield history`** — new command to list recent comparisons saved
+  in your Cloud account. Surfaces in `specshield --help` so local-only
+  users discover the feature exists.
+
+- **`specshield share <report-id | base.yaml target.yaml>`** — generate a
+  public shareable URL for a comparison. Designed for pasting diffs into
+  Slack, PR comments, or Jira. Cloud account required.
+
+Both new commands print a friendly "Get started in 30 seconds" message
+with a `specshield login` deep link when run without credentials.
+
+### Why
+
+Background: in May 2026 the CLI had 2,000+ active monthly users (npm download
+estimate; real human count likely 200-500) but the SpecShield Cloud signup
+rate from the CLI was effectively zero. Local compare was so capable that
+users got 100% of their immediate value without ever needing an account.
+
+These changes don't remove any free functionality — local compare is still
+fully usable without signup — they just make the gap between local and
+cloud visible at the moments when a user is most engaged (post-install,
+post-compare, on `--help`).
+
+### Tests
+
+- Added `tests/core/conversionPrompt.test.js` covering all skip conditions,
+  threshold logic, escalation, and 7-day window reset (10 tests).
+- All 134 existing tests still pass.
+
+### Opting out
+
+If you don't want the banner or contextual prompts:
+
+```sh
+export SPECSHIELD_NO_BANNER=1     # disable banner + post-compare nudge
+```
+
+Or just sign up — logged-in users never see either.

+## Comparison History
+
+Every `specshield compare --remote` is saved to your SpecShield account.
+List the recent comparisons your account has run from any machine — useful
+for tracking API drift over time across CI pipelines + local runs.
+
+```bash
+specshield history                # last 20 comparisons
+specshield history --limit 50     # show more
+specshield history --json         # machine-readable for scripts
+```
+
+```
+  Your recent comparisons
+  ─────────────────────────────────────────────────────
+  482        3 breaking         2026-05-17 14:30   payment-v1.yaml → payment-v2.yaml
+  481        0 breaking         2026-05-17 11:02   user-api.yaml → user-api-updated.yaml
+  480        7 breaking         2026-05-16 18:55   billing-v3.yaml → billing-v4.yaml
+```
+
+Account required — run `specshield login` to set up (free, no credit card).
+
+---
+
+## Share a Comparison
+
+Generate a public, tokenized URL for any comparison report. Anyone with
+the link can view the diff — no SpecShield account needed. Great for
+pasting into Slack threads, PR comments, or Jira tickets.
+
+```bash
+# Share an existing report by ID (from `specshield history`)
+specshield share 482
+
+# Compare two specs and share the result in one step
+specshield share base.yaml target.yaml
+
+# Time-limited link — expires in 30 days
+specshield share 482 --expires 30
+```
+
+```
+  ✔ Share link ready
+  ─────────────────────────────────────────────────────
+    https://specshield.io/r/_Ru8OVubxY3r9zHOsylESaULphCqBYH5jTPYldSMU88
+    Expires:  2026-06-16T12:34:56Z
+
+  Anyone with this link can view the diff — no SpecShield account required.
+```
+
+Links use a 256-bit random token, so they can't be guessed by enumeration.
+Revoke any time from your dashboard at [specshield.io](https://specshield.io).
