i see some fixes/improvements present in 8.5 but missing in 9.1  
why ?  
i example  
8.5 has

`decompiler: improved cfunc_t cache by introducing "saved_to_idb"; otherwise we were saving all decompiled functions upon each "save_database", again and again`

`BUGFIX: decompiler: value range optimization could lead to code being wrongly removed`

but in 9.1 missing

btw i wish option to disable store microcode into idb and doest use it anyway

It’s because those things were already fixed in [IDA 9.0 | Hex-Rays Docs](https://docs.hex-rays.com/release-notes/9_0).

It’s an internal flag used to avoid saving cached ctext repeatedly on each database save which was happening previously; it’s not intended to be controlled by the user.
