sh4lt 0.0.4 (2024-02-07)
---------------------------

---------------------------

New feature

Fix
* fix get_one_access resizes when resize is not needed

sh4lt 0.2.0 (2025-11-25)
---------------------------

Breaking changes:

* increase shtype max size from 4096 to 65536
* add speed in timeinfo structure

The port from sh4lt 0.1 to 0.2 requires to inform Sh4lt writers (`Writer` class) the speed when writing. An extra argument, `speed` (float), is required for the following methods:

* `copy_to_shm` now takes `float speed` as last argument. Normal speed is 1.0, and set as the default argument value for C++ and python. A speed of 2.0 is twice faster and a speed of 0.5 is twice slower. 0.0 is for offline, an negative values indicated a reversed playing. 
* same applies to `notify_clients`.

Breaking Changes:

* Python: simplification of `copy_to_shm`
* Rename pysh4lt into sh4lt
* Follower uses shared pointers on logger, and Python ctor has now optional arguments
