Release Notes: v3.2.0

What's New

EnableTestMode() — Switch to test endpoints (sms/testsend, sms/teststatus, sms/testlist). No real SMS are sent and no charges apply.
DisableTestMode() — Switch back to production mode.
IsTestModeActive() — Check whether test mode is enabled.

Useful for development and debugging without affecting your account balance.

New fat JAR artifact: smsaero-3.2.0-cli.jar with ru.smsaero.CommandLine as main class.

Send SMS from the command line:

java -jar smsaero-3.2.0-cli.jar --email YOUR_EMAIL --api_key YOUR_API_KEY --phone 70000000000 --message "Hello"

Supports environment variables: SMSAERO_EMAIL, SMSAERO_API_KEY, SMSAERO_PHONE, SMSAERO_MESSAGE, SMSAERO_SIGN.
Options: --sign (sender signature), --debug (test mode).

Run CLI in a container:

docker run --rm smsaero/smsaero_java:latest --email YOUR_EMAIL --api_key YOUR_API_KEY --phone 70000000000 --message "Hello"

Thread safety — Instance fields are now thread-local where needed; client is safe for concurrent use.
Retry logic — Automatic retry on transient network errors (timeouts, connection refused, etc.).
Validation — Constructor validates email and apiKey (non-null, non-blank); throws IllegalArgumentException on invalid input.
Timeouts — Configurable connect (10s) and read (30s) timeouts.
Javadoc — Added documentation for public API.

Minimum Java version: 11 — Java 8 is no longer supported. Use v3.1.0 for Java 8 projects.

Update Maven/Gradle dependency to 3.2.0.
Ensure your project uses Java 11+.
No API changes for existing SmsAero usage; new methods (EnableTestMode, etc.) are additive.
