Release Notes

v0.9.1b3

Issues: #304

Fix: MIC 2500-5500MTL-S entities all unavailable (Issue #304):
The inverter rejects Modbus reads of more than one register at a time (responds with
ExceptionResponse FC=132, exception_code=1 — Illegal Function for any block read).
Fixed by adding per-profile max_block_size support to the coordinator. When a profile
sets max_block_size: 1, the coordinator switches to sparse read mode: it reads only the
specific register addresses defined in the profile, grouped into consecutive runs of at most
max_block_size registers, skipping all gaps. This also eliminates unnecessary register reads
for registers not defined in the profile. All other profiles continue to use the original
dense read mode (contiguous 125-register block reads) unchanged.
