Mark the internal `createBootstrapSignedOutState` as deprecated. It is no longer used by `@clerk/nextjs` and is kept only for older published SDK versions.

In development, missing Clerk keys no longer activate keyless mode. When `NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY` and `CLERK_SECRET_KEY` are not set, the SDK now throws an error directing you to run `npx clerk@latest init`, which provisions a Clerk application and writes the keys to `.env.local`. Keyless credentials stored in the development keyless cookie are no longer read. Existing apps with configured or claimed keys are unaffected.

Clarify the missing-key condition.

The release note states that the error occurs when both variables are absent. The PR objective states that either missing variable triggers the shared error. Change and to or, or state that the error occurs when either variable is missing.

‼️IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Next.js 15 environment variables .env changes require restart NEXT_PUBLIC inlined client bundle

💡 Result:

In Next.js 15, handling environment variables involves two distinct behaviors depending on the environment and whether the variable is prefixed with NEXT_PUBLIC_ [1][2]. 1. Development Mode (next dev): Next.js reads.env files only once when the development server starts [1][3]. If you add, remove, or modify any environment variables in your.env files while the server is running, you must manually restart the server (Ctrl+C and run npm run dev again) for the changes to take effect [4][1][5]. Hot Module Replacement (HMR) does not automatically update environment variables [1][3]. 2. Production (next build): Variables prefixed with NEXT_PUBLIC_ are inlined into the client-side JavaScript bundle at build time [6][7][2]. Because these values are replaced with hard-coded strings during the build process, they are "frozen" and cannot be updated at runtime [6][1][8]. If you change a NEXT_PUBLIC_ variable in your environment (e.g., in a dashboard like Vercel or in a Docker container), you must trigger a new build and redeploy the application to update the client bundle [1][7][3]. Server-only variables (those without the NEXT_PUBLIC_ prefix) are read at runtime in the Node.js environment [7][3]. While these do not require a rebuild if changed in your hosting environment, you must still restart your server process for them to be picked up if they were loaded from a local.env file or if the runtime environment process requires a refresh [1][3]. To avoid issues: - Always restart your development server after editing.env files [1][5]. - Only use the NEXT_PUBLIC_ prefix for variables that explicitly need to be accessible in the browser [6][2]. - Treat NEXT_PUBLIC_ variables as build-time constants rather than runtime configuration [1][7].

Citations:

Restart the Next.js dev server after copying the keys.

app.keylessToEnv() updates .env, but the running Next.js process does not reload environment variables after five seconds. Replace the delay with await app.restart() before navigating to the claimed-key scenario.

In development, missing Clerk keys no longer activate keyless mode. When `NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY` and `CLERK_SECRET_KEY` are not set, the SDK now throws an error directing you to run `npx clerk@latest init`, which provisions a Clerk application and writes the keys to `.env.local`. Keyless credentials stored in the development keyless cookie are no longer read. Existing apps with configured or claimed keys are unaffected.

Suggested change

In development, missing Clerk keys no longer activate keyless mode. When `NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY`and`CLERK_SECRET_KEY`are not set, the SDK now throws an error directing you to run `npx clerk@latest init`, which provisions a Clerk application and writes the keys to `.env.local`. Keyless credentials stored in the development keyless cookie are no longer read. Existing apps with configured or claimed keys are unaffected.

Next.js 15 environment variables .env changes require restart NEXT_PUBLIC inlined client bundle
💡 Result:
In Next.js 15, handling environment variables involves two distinct behaviors depending on the environment and whether the variable is prefixed with NEXT_PUBLIC_ [1][2]. 1. Development Mode (next dev): Next.js reads.env files only once when the development server starts [1][3]. If you add, remove, or modify any environment variables in your.env files while the server is running, you must manually restart the server (Ctrl+C and run npm run dev again) for the changes to take effect [4][1][5]. Hot Module Replacement (HMR) does not automatically update environment variables [1][3]. 2. Production (next build): Variables prefixed with NEXT_PUBLIC_ are inlined into the client-side JavaScript bundle at build time [6][7][2]. Because these values are replaced with hard-coded strings during the build process, they are "frozen" and cannot be updated at runtime [6][1][8]. If you change a NEXT_PUBLIC_ variable in your environment (e.g., in a dashboard like Vercel or in a Docker container), you must trigger a new build and redeploy the application to update the client bundle [1][7][3]. Server-only variables (those without the NEXT_PUBLIC_ prefix) are read at runtime in the Node.js environment [7][3]. While these do not require a rebuild if changed in your hosting environment, you must still restart your server process for them to be picked up if they were loaded from a local.env file or if the runtime environment process requires a refresh [1][3]. To avoid issues: - Always restart your development server after editing.env files [1][5]. - Only use the NEXT_PUBLIC_ prefix for variables that explicitly need to be accessible in the browser [6][2]. - Treat NEXT_PUBLIC_ variables as build-time constants rather than runtime configuration [1][7].
Citations:
Restart the Next.js dev server after copying the keys.
app.keylessToEnv() updates .env, but the running Next.js process does not reload environment variables after five seconds. Replace the delay with await app.restart() before navigating to the claimed-key scenario.

In development, missing Clerk keys no longer activate keyless mode. When `NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY` and `CLERK_SECRET_KEY` are not set, the SDK now throws an error directing you to run `npx clerk@latest init`, which provisions a Clerk application and writes the keys to `.env.local`. Keyless credentials stored in the development keyless cookie are no longer read. Existing apps with configured or claimed keys are unaffected.

Next.js 15 environment variables .env changes require restart NEXT_PUBLIC inlined client bundle
💡 Result:
In Next.js 15, handling environment variables involves two distinct behaviors depending on the environment and whether the variable is prefixed with NEXT_PUBLIC_ [1][2]. 1. Development Mode (next dev): Next.js reads.env files only once when the development server starts [1][3]. If you add, remove, or modify any environment variables in your.env files while the server is running, you must manually restart the server (Ctrl+C and run npm run dev again) for the changes to take effect [4][1][5]. Hot Module Replacement (HMR) does not automatically update environment variables [1][3]. 2. Production (next build): Variables prefixed with NEXT_PUBLIC_ are inlined into the client-side JavaScript bundle at build time [6][7][2]. Because these values are replaced with hard-coded strings during the build process, they are "frozen" and cannot be updated at runtime [6][1][8]. If you change a NEXT_PUBLIC_ variable in your environment (e.g., in a dashboard like Vercel or in a Docker container), you must trigger a new build and redeploy the application to update the client bundle [1][7][3]. Server-only variables (those without the NEXT_PUBLIC_ prefix) are read at runtime in the Node.js environment [7][3]. While these do not require a rebuild if changed in your hosting environment, you must still restart your server process for them to be picked up if they were loaded from a local.env file or if the runtime environment process requires a refresh [1][3]. To avoid issues: - Always restart your development server after editing.env files [1][5]. - Only use the NEXT_PUBLIC_ prefix for variables that explicitly need to be accessible in the browser [6][2]. - Treat NEXT_PUBLIC_ variables as build-time constants rather than runtime configuration [1][7].
Citations:
Restart the Next.js dev server after copying the keys.
app.keylessToEnv() updates .env, but the running Next.js process does not reload environment variables after five seconds. Replace the delay with await app.restart() before navigating to the claimed-key scenario.

In development, missing Clerk keys no longer activate keyless mode. When `NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY` and `CLERK_SECRET_KEY` are not set, the SDK now throws an error directing you to run `npx clerk@latest init`, which provisions a Clerk application and writes the keys to `.env.local`. Keyless credentials stored in the development keyless cookie are no longer read. Existing apps with configured or claimed keys are unaffected.

Next.js 15 environment variables .env changes require restart NEXT_PUBLIC inlined client bundle
💡 Result:
In Next.js 15, handling environment variables involves two distinct behaviors depending on the environment and whether the variable is prefixed with NEXT_PUBLIC_ [1][2]. 1. Development Mode (next dev): Next.js reads.env files only once when the development server starts [1][3]. If you add, remove, or modify any environment variables in your.env files while the server is running, you must manually restart the server (Ctrl+C and run npm run dev again) for the changes to take effect [4][1][5]. Hot Module Replacement (HMR) does not automatically update environment variables [1][3]. 2. Production (next build): Variables prefixed with NEXT_PUBLIC_ are inlined into the client-side JavaScript bundle at build time [6][7][2]. Because these values are replaced with hard-coded strings during the build process, they are "frozen" and cannot be updated at runtime [6][1][8]. If you change a NEXT_PUBLIC_ variable in your environment (e.g., in a dashboard like Vercel or in a Docker container), you must trigger a new build and redeploy the application to update the client bundle [1][7][3]. Server-only variables (those without the NEXT_PUBLIC_ prefix) are read at runtime in the Node.js environment [7][3]. While these do not require a rebuild if changed in your hosting environment, you must still restart your server process for them to be picked up if they were loaded from a local.env file or if the runtime environment process requires a refresh [1][3]. To avoid issues: - Always restart your development server after editing.env files [1][5]. - Only use the NEXT_PUBLIC_ prefix for variables that explicitly need to be accessible in the browser [6][2]. - Treat NEXT_PUBLIC_ variables as build-time constants rather than runtime configuration [1][7].
Citations:
Restart the Next.js dev server after copying the keys.
app.keylessToEnv() updates .env, but the running Next.js process does not reload environment variables after five seconds. Replace the delay with await app.restart() before navigating to the claimed-key scenario.

In development, missing Clerk keys no longer activate keyless mode. When `NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY` and `CLERK_SECRET_KEY` are not set, the SDK now throws an error directing you to run `npx clerk@latest init`, which provisions a Clerk application and writes the keys to `.env.local`. Keyless credentials stored in the development keyless cookie are no longer read. Existing apps with configured or claimed keys are unaffected.

Next.js 15 environment variables .env changes require restart NEXT_PUBLIC inlined client bundle
💡 Result:
In Next.js 15, handling environment variables involves two distinct behaviors depending on the environment and whether the variable is prefixed with NEXT_PUBLIC_ [1][2]. 1. Development Mode (next dev): Next.js reads.env files only once when the development server starts [1][3]. If you add, remove, or modify any environment variables in your.env files while the server is running, you must manually restart the server (Ctrl+C and run npm run dev again) for the changes to take effect [4][1][5]. Hot Module Replacement (HMR) does not automatically update environment variables [1][3]. 2. Production (next build): Variables prefixed with NEXT_PUBLIC_ are inlined into the client-side JavaScript bundle at build time [6][7][2]. Because these values are replaced with hard-coded strings during the build process, they are "frozen" and cannot be updated at runtime [6][1][8]. If you change a NEXT_PUBLIC_ variable in your environment (e.g., in a dashboard like Vercel or in a Docker container), you must trigger a new build and redeploy the application to update the client bundle [1][7][3]. Server-only variables (those without the NEXT_PUBLIC_ prefix) are read at runtime in the Node.js environment [7][3]. While these do not require a rebuild if changed in your hosting environment, you must still restart your server process for them to be picked up if they were loaded from a local.env file or if the runtime environment process requires a refresh [1][3]. To avoid issues: - Always restart your development server after editing.env files [1][5]. - Only use the NEXT_PUBLIC_ prefix for variables that explicitly need to be accessible in the browser [6][2]. - Treat NEXT_PUBLIC_ variables as build-time constants rather than runtime configuration [1][7].
Citations:
Restart the Next.js dev server after copying the keys.
app.keylessToEnv() updates .env, but the running Next.js process does not reload environment variables after five seconds. Replace the delay with await app.restart() before navigating to the claimed-key scenario.

In development, missing Clerk keys no longer activate keyless mode. When `NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY` and `CLERK_SECRET_KEY` are not set, the SDK now throws an error directing you to run `npx clerk@latest init`, which provisions a Clerk application and writes the keys to `.env.local`. Keyless credentials stored in the development keyless cookie are no longer read. Existing apps with configured or claimed keys are unaffected.

Clarify the missing-key condition.
The release note states that the error occurs when both variables are absent. The PR objective states that either missing variable triggers the shared error. Change and to or, or state that the error occurs when either variable is missing.

Next.js 15 environment variables .env changes require restart NEXT_PUBLIC inlined client bundle
💡 Result:
In Next.js 15, handling environment variables involves two distinct behaviors depending on the environment and whether the variable is prefixed with NEXT_PUBLIC_ [1][2]. 1. Development Mode (next dev): Next.js reads.env files only once when the development server starts [1][3]. If you add, remove, or modify any environment variables in your.env files while the server is running, you must manually restart the server (Ctrl+C and run npm run dev again) for the changes to take effect [4][1][5]. Hot Module Replacement (HMR) does not automatically update environment variables [1][3]. 2. Production (next build): Variables prefixed with NEXT_PUBLIC_ are inlined into the client-side JavaScript bundle at build time [6][7][2]. Because these values are replaced with hard-coded strings during the build process, they are "frozen" and cannot be updated at runtime [6][1][8]. If you change a NEXT_PUBLIC_ variable in your environment (e.g., in a dashboard like Vercel or in a Docker container), you must trigger a new build and redeploy the application to update the client bundle [1][7][3]. Server-only variables (those without the NEXT_PUBLIC_ prefix) are read at runtime in the Node.js environment [7][3]. While these do not require a rebuild if changed in your hosting environment, you must still restart your server process for them to be picked up if they were loaded from a local.env file or if the runtime environment process requires a refresh [1][3]. To avoid issues: - Always restart your development server after editing.env files [1][5]. - Only use the NEXT_PUBLIC_ prefix for variables that explicitly need to be accessible in the browser [6][2]. - Treat NEXT_PUBLIC_ variables as build-time constants rather than runtime configuration [1][7].
Citations:
Restart the Next.js dev server after copying the keys.
app.keylessToEnv() updates .env, but the running Next.js process does not reload environment variables after five seconds. Replace the delay with await app.restart() before navigating to the claimed-key scenario.

In development, missing Clerk keys no longer activate keyless mode. When `NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY` and `CLERK_SECRET_KEY` are not set, the SDK now throws an error directing you to run `npx clerk@latest init`, which provisions a Clerk application and writes the keys to `.env.local`. Keyless credentials stored in the development keyless cookie are no longer read. Existing apps with configured or claimed keys are unaffected.

Next.js 15 environment variables .env changes require restart NEXT_PUBLIC inlined client bundle
💡 Result:
In Next.js 15, handling environment variables involves two distinct behaviors depending on the environment and whether the variable is prefixed with NEXT_PUBLIC_ [1][2]. 1. Development Mode (next dev): Next.js reads.env files only once when the development server starts [1][3]. If you add, remove, or modify any environment variables in your.env files while the server is running, you must manually restart the server (Ctrl+C and run npm run dev again) for the changes to take effect [4][1][5]. Hot Module Replacement (HMR) does not automatically update environment variables [1][3]. 2. Production (next build): Variables prefixed with NEXT_PUBLIC_ are inlined into the client-side JavaScript bundle at build time [6][7][2]. Because these values are replaced with hard-coded strings during the build process, they are "frozen" and cannot be updated at runtime [6][1][8]. If you change a NEXT_PUBLIC_ variable in your environment (e.g., in a dashboard like Vercel or in a Docker container), you must trigger a new build and redeploy the application to update the client bundle [1][7][3]. Server-only variables (those without the NEXT_PUBLIC_ prefix) are read at runtime in the Node.js environment [7][3]. While these do not require a rebuild if changed in your hosting environment, you must still restart your server process for them to be picked up if they were loaded from a local.env file or if the runtime environment process requires a refresh [1][3]. To avoid issues: - Always restart your development server after editing.env files [1][5]. - Only use the NEXT_PUBLIC_ prefix for variables that explicitly need to be accessible in the browser [6][2]. - Treat NEXT_PUBLIC_ variables as build-time constants rather than runtime configuration [1][7].
Citations:
Restart the Next.js dev server after copying the keys.
app.keylessToEnv() updates .env, but the running Next.js process does not reload environment variables after five seconds. Replace the delay with await app.restart() before navigating to the claimed-key scenario.

In development, missing Clerk keys no longer activate keyless mode. When `NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY` and `CLERK_SECRET_KEY` are not set, the SDK now throws an error directing you to run `npx clerk@latest init`, which provisions a Clerk application and writes the keys to `.env.local`. Keyless credentials stored in the development keyless cookie are no longer read. Existing apps with configured or claimed keys are unaffected.

Next.js 15 environment variables .env changes require restart NEXT_PUBLIC inlined client bundle
💡 Result:
In Next.js 15, handling environment variables involves two distinct behaviors depending on the environment and whether the variable is prefixed with NEXT_PUBLIC_ [1][2]. 1. Development Mode (next dev): Next.js reads.env files only once when the development server starts [1][3]. If you add, remove, or modify any environment variables in your.env files while the server is running, you must manually restart the server (Ctrl+C and run npm run dev again) for the changes to take effect [4][1][5]. Hot Module Replacement (HMR) does not automatically update environment variables [1][3]. 2. Production (next build): Variables prefixed with NEXT_PUBLIC_ are inlined into the client-side JavaScript bundle at build time [6][7][2]. Because these values are replaced with hard-coded strings during the build process, they are "frozen" and cannot be updated at runtime [6][1][8]. If you change a NEXT_PUBLIC_ variable in your environment (e.g., in a dashboard like Vercel or in a Docker container), you must trigger a new build and redeploy the application to update the client bundle [1][7][3]. Server-only variables (those without the NEXT_PUBLIC_ prefix) are read at runtime in the Node.js environment [7][3]. While these do not require a rebuild if changed in your hosting environment, you must still restart your server process for them to be picked up if they were loaded from a local.env file or if the runtime environment process requires a refresh [1][3]. To avoid issues: - Always restart your development server after editing.env files [1][5]. - Only use the NEXT_PUBLIC_ prefix for variables that explicitly need to be accessible in the browser [6][2]. - Treat NEXT_PUBLIC_ variables as build-time constants rather than runtime configuration [1][7].
Citations:
Restart the Next.js dev server after copying the keys.
app.keylessToEnv() updates .env, but the running Next.js process does not reload environment variables after five seconds. Replace the delay with await app.restart() before navigating to the claimed-key scenario.
