CloudScale Backup & Restore

3.2.592

• FIX: Fatal-error-handler drop-in now written via the WordPress Filesystem API instead of raw copy() (resolves Plugin Check PluginDirectoryWrite)
• FIX: Crash Recovery config and notification lock moved from the wp-content root into uploads/cloudscale-backup/ per WordPress.org guidelines; old files removed on upgrade
• FIX: Removed wp_prime_option_caches() (WordPress 6.4+) so the plugin stays compatible with its declared minimum of WordPress 6.0
• CHANGE: Drop-in notifications now use the non-blocking wp_remote_post() HTTP API instead of cURL
• CHANGE: Dev-only crash-test harness and clone module excluded from the release build; removed duplicate Plugin URI header

3.2.421

• FIX: Remove four dead wp_ajax_csbr_do_sync_job_* handlers that called undefined function csbr_do_async_sync(), legacy loopback architecture replaced by register_shutdown_function() in v3.2.257
• FIX: Automatic Crash Recovery Explain modal and How It Works list now correctly document all notification channels (email, Twilio SMS, ntfy push) instead of only Twilio
• ADD: DocBlocks added to csbr_set_job(), csbr_get_job(), csbr_delete_job(), csbr_find_rclone(), csbr_find_aws(), csbr_list_tables_in_dump(), csbr_list_backups()
• CLEANUP: Remove unused csbr_verify_nonce() helper (all handlers use check_ajax_referer() directly)

3.2.257

• FIX: PCP compliance: cs_admin_page() now independently checks current_user_can(‘manage_options’)
• FIX: PCP compliance: wp_unslash() added to $_POST[‘cs_action’] and $_POST[‘schedule_enabled’]; phpcs:ignore annotations added
• FIX: PCP compliance: data-free-bytes attribute annotated with phpcs:ignore EscapeOutput.OutputNotEscaped
• FIX: uninstall.php: Dropbox options now cleaned up on plugin delete
• FIX: Dropbox history pane infinite reload loop resolved
• FIX: AMI Save/Create buttons now show feedback message correctly
• UX: Copy buttons on all Explain modal code blocks; Dropbox setup wizard guide; italic placeholders

3.2.1

• Renamed internal constants with CS_BACKUP_ prefix to avoid collisions with other plugins
• Replaced @unlink(), @copy(), @rmdir() with wp_delete_file(), copy(), rmdir() per WordPress coding standards

3.2.0

• NEW: Split backup scheduling into two independent cron events: file backup and AMI snapshot each have their own day picker and time selector
• NEW: Configurable backup filename prefix (default: bkup), set in the Retention card
• NEW: S3 sync auto-retry: on failure a single cron event fires 5 minutes later; UI shows pending state and a manual Retry button
• FIX: Scheduled backup run hour never saved due to missing name attribute on the hour select
• FIX: Full+ backup type badge now renders distinctly from Full (separate CSS rule)
• AMI explain modal updated to document the two-schedule architecture; reboot defaults clarified (off = crash-consistent, no downtime)

2.74.2

• FIX: AMI creation failed with “Character sets beyond ASCII are not supported” due to em dash in description
• AMI description now stripped to printable ASCII only via regex
• AMI name now sanitised to AWS allowed characters (alphanumeric, hyphens, underscores, dots, slashes, parens) and capped at 128 chars
• Replaced sanitize_file_name with stricter AWS specific character filter

2.74.1

• FIX: AMI panel could vanish if IMDS endpoint was unreachable or curl failed during page render
• All IMDS calls now wrapped in try/catch with error suppression so failures cannot break the admin page
• Added curl_init availability check before attempting IMDS calls
• IMDS results cached in WordPress transients (1 hour TTL) to avoid repeated metadata calls on every page load
• AMI panel init block wrapped in top level try/catch, falls back to empty state on any error

2.74.0

• NEW: EC2 AMI Snapshot panel: create full machine images of the hosting instance directly from the plugin
• AMI name uses configurable prefix with automatic yyyyMMdd_HHmm timestamp suffix
• Optional instance reboot for filesystem consistent snapshots

• Check Status button to poll AMI state from AWS
