Bug with symbol library 5.99?

[BobZ]

Well…I just found that my pins were somehow set to “invisible”. This seems strange because I think I have used the symbol before. But anyway that was easy to fix…fingers crossed hoping that the below is resolved.

Also I get "This file was created by an older version of KiCad. It will be converted to the new format when saved. " But it was created with 5.99 from January.Bobs_Power_Switching_ICs.kicad_sym (31.6 KB)

I have attached the project folder. EDIT: I have also now uploaded my symbol library folder.

Also I get "This file was created by an older version of KiCad. It will be converted to the new format when saved. " But it was created with 5.99 from

I also have struck this warning more than once.
I just assumed that, being a development program, last weeks 5.99 was an older version than this weeks 5.99.

I , however, would not be at all perturbed if my assumption is corrected by anyone.

There was a couple of bug that needed fixed and the had to increase the file version:

[5.99] Has PCB file format changed in the last week?

There have been a few bug fixes that required bumping the file format version even though we passed the “freeze” point – the freeze mostly means that no new features will come in to the file formats.

Thank you, Ulises and Janek K.

I take this to mean that the new file formats are not backwards compatible to older 5.99 builds… I am not sure that it matters to me, but if there is such backwards incompatibility, does it apply to pcb only or schematic also?

There are some changes in the PCB format, but it can be hacked back to a previous version with a text editor.

Not so for the schematic. File format has been completely changed to a new “S-expression” format and is very much different from older versions.

I do not know about the library formats.

Thanks, paulvdh. With fingers crossed, I will say that for my purposes, forward compatibility ought to be adequate. Sometimes we need to let bygones be bygones. I did like the particular build that I was using.
