 ### Changed
 
-- `Property::setValue(float)` publishes the shortest decimal that reads back as the same float, laid out like python-sdk's float text: `21.4`, `40.0`, `1e-05`, `1e16` instead of `21.400000`. The formatters are `homie_format_float()` and `homie_format_double()` in `ebus/homie/homie_datatype.h`.

 ## Status
 
-Version 0.6.0, alpha. Known limits:
+Version 0.7.0, alpha. Known limits:
 
 - The POSIX demo build has no TLS; it connects to plain-TCP brokers only.
-- After a broker loses its retained messages, esp32-sdk's reconnect does not restore `$description`; it does not yet call `Device::forgetDescriptionHash()` ([After a reconnect](doc/core.md#after-a-reconnect)).
 - The driver contract (`NodeEntity`, `NodeProperty`) is still in esp32-sdk ([why](doc/core.md#still-in-esp32-sdk)).
 - The code-first API has rough edges found while writing the POSIX demo: registering a settable property needs a live connection, and the controller has no change callback.
 - esp32-sdk is not public yet; links to it will resolve once it is.
