Head's Up: Follow-On Bug Fix Sigil 2.8.6 coming asap

[KevinH]

Hi All,

A few minor and one major bug has been reported and fixed for Sigil 2.8.5, so we are going to make a fast follow-on Sigil 2.8.6 bug fix only release as soon as possible.

The major bug only hits Sigil 2.8.5 when editing an epub3 and then changing the cover image. Adding an initial cover works, just not changing one. The bug does *not* hit when editing epub2. This bug can cause a random OPF manifest entry to be updated which unless a Checkpoint was made will most likely result in data loss. Therefore the fast follow on release of Sigil 2.8.6 will be made.

If you already have updated to Sigil 2.8.5, you have two choices:

1. downgrade by installing Sigil 2.8.1 over it

or

2. wait for Sigil 2.8.6 which is coming asap but you must refrain from changing the cover image under epub3 (and always use CheckPoints).

If you have already completed editing an epub3 and did change the cover of an epub3, then you should carefully examine that epub closely to see which if any manifest entry (and therefore chapter file, image, etc) might have been impacted and replace it from a Checkpoint or earlier saved version of the epub. If you did not change an existing cover of an epub3, you are completely safe from this bug.

We wanted you to know as soon as the bug was reported, verified, and diagnosed (which happened late yesterday).

And fwiw, this bug which was introduced in Sigil 2.8.5 and did not exist in earlier versions was entirely my fault which just means my age is beginning to show and that I need to be much more careful in the future (and I will). Even after extensive use and testing over weeks and weeks, because it only triggered when changing an existing cover of a epub3, it was missed. I apologize.

All the bug fixes are available in Sigil master right now. So if you build your own, you can update and build from Sigil master now and have exactly what will be released as Sigil 2.8.6 shortly.

I have removed the Sigil 2.8.5 binaries from our release page for increased safety.

Thank you!
