Version 26.0.0
--------------

*Released on February 18, 2026*

Improvements
^^^^^^^^^^^^

- **Asynchronous task execution**: Otter now supports both synchronous and asynchronous
  tasks, with improved run logic and better coordination by using pull-style workers and
  a more robust process pool management system (:commit:`086911a`, :commit:`b5d7dea`,
  :commit:`2c8f37e`, :commit:`f0e697e`)
- **Improved storage handling**: File operations are now handled through "StorageHandle"
  and "AsyncStorageHandle" classes which provide a consistent interface for local and
  cloud storage. (:commit:`aa6da20`, :commit:`7e84c40`, :commit:`dc2e4d2`, :commit:`0c37f92`,
  :commit:`6e62d59`)
- **New copy_many task for batch operations**: A new builtin task enables efficient copying
  of multiple files at once. This task is better suited for copying a large amount (100+) of
  relatively small (tens of MB) files. It avoids spawning a new process and a new client for
  each file. It supports passing a list of sources, a path to a file with a list of sources,
  or a glob (when copying from backends that can handle those, like cloud services).
