Changelog

Tracks changes to @bitlogin/core and @bitlogin/widget that matter to a site with its own vendored copy (see "Updating your integration" in README.md). Not every commit needs an entry — only ones where a site sitting on an older vendored copy is missing a fix or behavior change it would plausibly want. Newest first.

• Fix: registration/login could fail quorum if a single built-in relay was down. BUILTIN_VAULT_RELAYS had only 3 relays and BUILTIN_DISCOVERY_RELAYS only 2, sharing relay.nostr.band between both lists. publishAndVerify() requires a fixed minAcks/minReadbacks of 2 regardless of relay count, so losing that one relay left zero margin — surfacing as "Registration did not reach the required relay acknowledgement and readback quorum." Added nostr.wine and relay.snort.social to the vault list, and nostr-pub.wellorder.net to discovery. (681f622) Re-vendor if: your site uses the default built-in relay list (i.e. you don't pass your own vault-relays/discovery-relays attributes). If you already pass your own relay list, this doesn't affect you.

• Fix: widget completely unstyled (giant logo, unstyled buttons) under a strict style-src CSP. element.ts injected its CSS as an inline <style> tag inside the shadow root on every render. A host with style-src 'self' and no 'unsafe-inline' silently drops an inline <style>'s rules entirely — visible as the brand SVG rendering at its raw ~590×119px intrinsic size instead of the intended 20px-tall lockup, with every other shadow-DOM element similarly falling back to unstyled browser defaults. Switched to building the stylesheet once as a CSSStyleSheet and assigning it via adoptedStyleSheets, which isn't subject to style-src. (e8712f9) Re-vendor if: your site's CSP sets style-src without 'unsafe-inline' (check your CSP header/meta tag). If your style-src already includes 'unsafe-inline', or you have no CSP, this was invisible to you either way, but re-vendoring is still a good idea (this fix also drops needless per-render CSS reparsing).

• Feature: NIP-04 support, for drop-in parity with a real NIP-07 extension. window.nostr.nip04 (and the element-scoped nip04Encrypt/nip04Decrypt) didn't exist at all before this — only NIP-44 was implemented. A site (or its own legacy DM code path) calling window.nostr.nip04.encrypt(...) while BitLogin was the active signer got Cannot read properties of undefined instead of a working call. (2838402) Re-vendor if: your site (or any third-party code running on it) uses window.nostr.nip04 — a real NIP-07 extension always has it, so anything written against "whatever window.nostr provides" may already assume it's there. No attribute/config changes needed; this is purely additive.

• Feature: sessions persist across a page reload. Previously every reload destroyed the crypto worker, requiring the full login-name + password flow again — re-running Argon2id and a relay quorum read on every navigation, not just the first sign-in. After a successful register/login/recover/ changePassword, the everyday private key and active capsule events are now cached in IndexedDB; connectedCallback() tries to restore that cache before ever showing the welcome screen, firing bitlogin-login exactly as a fresh login would if one is found. Logout clears it. (9e3787d) Security note: this means the decrypted everyday private key now sits in the browser's IndexedDB for that origin until logout — the same tradeoff every NIP-07 extension and crypto wallet already makes for the same "don't ask for the password every navigation" reason, scoped by IndexedDB's own per-origin isolation. The recovery phrase and login name/password are never cached. Re-vendor if: you want this — it's the reason to re-vendor this entry. No attribute/config or host-integration changes needed; a host page's existing bitlogin-login listener (see "Embedding BitLogin" below) fires the same way whether the sign-in was just typed or silently restored.
