Since raising the version of the 'Likes and Replies' plugin to 0.9.0 and calling it a release candidate I don't think I've come across any problems. It's hard to believe that the last commit logged on GitHub was 17 days ago.
Where does the time go?
There might be some tidying up I could do to the code but, on the whole, I think it's achieved exactly what I was after and reached its natural conclusion.
That's not to say there won't be future updates if I think of new functionality, find problems or want to do things differently. But, for now, I think it's safe to put down a marker and bump it to a 1.0 release.
Although the plugin is reasonably simple I've learnt some good techniques which can be applied again and again while also learning from mistakes that, hopefully, won't be repeated.
It's been fun to go through the process of documenting this publicly, with nowhere to hide, and am glad I could contribute something to those who may use it.
