Processes v7.0.0

v7.0.0 (2026-06-20)

BREAKING CHANGE

• Task(channels=...) and the NotificationChannel API are removed;
  HTMLEmailStyle.style and traced_vars_frame_filter are removed (the latter moves
  to Task). Per-task email/webhook alerts are replaced by report.notify.

Feat

• add process name to report, email subject, and webhook payload
• normalize task names to lowercase for case-insensitive matching
• delegate notifications to ProcessExecutionReport, drop per-task channels
• replace notify_errors with notify(only_errors=...) and add task filter
• implement WebhookChannel and EmailChannel send_report
• add ReportChannel architecture for report notifications
• add ProcessExecutionReport.notify/.notify_errors stubs
• add ProcessExecutionReport.to_json
• add graph mutation methods to Process

Refactor

• group communication code into a comms/ package
• unify SMTP and webhook transport behind single classes
• extract task value types to leaf module, break import cycle

Perf

• cache palette CSS and report template loading
• cache language string loading
• add slots=True to frozen value types

v6.0.0 (2026-06-15)

BREAKING CHANGE

• Process.run() returns ProcessExecutionReport instead of
  ProcessResult. Use report.successes / report.errored / report.skipped
  instead of passed_tasks_results / errored_tasks / skipped_tasks, and
  report.entries[name].result / .error instead of
  passed_tasks_results[name] / failed_tasks_results[name].

Feat

• remove ProcessResult, have Process.run() return ProcessExecutionReport
• expand TaskStatus with PENDING and add status field to TaskResult
• add ProcessExecutionReport for per-task execution summaries
• track failed task results in ProcessRunner and ProcessResult
• promote ErrorData to public API and add timing/attempts to TaskResult

Fix

• make Task.run never propagate dependency-resolution failures

Refactor

• drop _is_unrunnable side effect and reuse TaskResult helpers

v5.0.0 (2026-06-14)

BREAKING CHANGE

• log_path and func swap positions; existing positional
  Task(name, log_path, func, ...) calls must be updated to
  Task(name, func, log_path, ...).

Feat

• add nest_under option to WebhookConfig for nested payload envelopes
• make Task.log_path optional, reorder constructor signature

v4.1.0 (2026-06-14)

Feat

• add extra_payload to WebhookConfig for service-specific routing keys
• include traced variables in task logfiles
• add generic WebhookChannel with optional HMAC body signing

Refactor

• make traced_vars a plain {name: repr(value)} dict

v4.0.0 (2026-06-14)

BREAKING CHANGE

• Task no longer accepts smtp_config or email_style.
  Pass channels=[EmailChannel(smtp_config, style)] instead.

Feat

• add NotificationChannel abstraction with file and email channels

Refactor

• configure email alerts via channels instead of Task smtp_config
• keep file and email channel implementations internal
• build task handlers through notification channels
