Marten 1.0.0 release notes

Under development.

Requirements and compatibility​

  • Crystal: 1.17, 1.18, 1.19, 1.20, and 1.21.
  • Databases:
    • MariaDB 10.11 and higher.
    • MySQL 8.4 and higher.
    • PostgreSQL 15 and higher.
    • SQLite 3.37.0 and higher.

New features​

Models and databases​

  • Query sets now provide a #each_batch method, allowing to iterate over large query sets in batches without loading all the matching records into memory at once. Records are fetched in batches using a primary key cursor and are always processed in ascending primary key order.

Backward incompatible changes​

Handlers and HTTP​

  • The default value of the trailing_slash setting is now :remove, so unresolved URLs ending with a trailing slash are permanently redirected to their slashless version by default. Applications that want to keep the previous behavior should explicitly set config.trailing_slash = :do_nothing.
