It can be minor if the SDK API and supported runtimes are unchanged. | +| Default network or RPC URL changed | Major or minor | Changing a default from mainnet to testnet is major. Rotating to an equivalent healthy RPC endpoint is minor if behavior is unchanged. | +| Bug fix that changes buggy behavior | Patch or major | Fixing an invalid checksum calculation is patch if it makes documented behavior work. Changing accepted malformed meta-addresses to throw is major if users may rely on parsing them. | When a change is ambiguous, choose the larger bump and document why in the changelog. diff --git a/examples/react-native-stellar/polyfills.ts b/examples/react-native-stellar/polyfills.ts index e983080..b64410c 100644 --- a/examples/react-native-stellar/polyfills.ts +++ b/examples/react-native-stellar/polyfills.ts @@ -14,7 +14,7 @@ if (typeof globalThis.atob === 'undefined') { let buffer; const chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/='; - for (let idx = 0; (buffer = base64.charAt(idx++));) { + for (let idx = 0; (buffer = base64.charAt(idx++)); ) { const code = chars.indexOf(buffer); if (code === -1) continue; bs = (bs << 6) | code; diff --git a/examples/stellar-chrome-extension/src/lib/types.ts b/examples/stellar-chrome-extension/src/lib/types.ts index bd530a5..1428858 100644 --- a/examples/stellar-chrome-extension/src/lib/types.ts +++ b/examples/stellar-chrome-extension/src/lib/types.ts @@ -71,4 +71,5 @@ export type PopupMessage = | { type: 'disconnect' }; export type WorkerResponse = - { ok: true; state?: ScanState; wallet?: ConnectedWallet | null } | { ok: false; error: string }; + | { ok: true; state?: ScanState; wallet?: ConnectedWallet | null } + | { ok: false; error: string }; diff --git a/examples/stellar-vue-receive/src/App.vue b/examples/stellar-vue-receive/src/App.vue index 59a28bd..fbfc535 100644 --- a/examples/stellar-vue-receive/src/App.vue +++ b/examples/stellar-vue-receive/src/App.vue @@ -164,7 +164,8 @@ const replacer = (_: string, v: unknown) => (v instanceof Uint8Array ?
