The work on Persy as now, is mainly around stabilization, there are a set of new features that I would love to add, but crash testing and fixing relative discovery is taking the priority.

Between the last minor and this there have been 7 patch releases, that solved a bunch of issue reported by the users, but some problems required major re-work and could not be fixed in a patch release, so changes are included in this release. Checking the diff with the previous release on git, the stats are 47 files changed, 3552 insertions(+), 903 deletions(-), this amount of changes is comparable with the previous minor releases so everything looks fairly normal, even though the complexity of some changes has been quite higher, so it took additional time to get done.

]]>http://perys.rs/posts/persy-0.5.htmlMon, 20 May 2019 21:00:30 -0500What's wrong with the colors of this website?http://perys.rs/posts/wrong-colors.htmlSo the truth is that I'm really bad designing something that look decent, and at the same time I don't want to get down to a preset design from a css framework I want something unique, In the process to get out something that look decent, every new release I try a new color style hoping that after some attempts statistically I will get something that look decent, or someone with better skill than me get so upset that he does it for me.

✓ Internal refactor to split transaction recover logic from transaction runtime logic. ✓ Add new method for inspect journal without actually executing a recover.
