Hi there!
I just want to know how can I remove post history? For example my post have 6 revision. But I want to remove 5 of them. They waste my disk usage. OK, I know maybe it is not too much. But if you think about total 10k post with 6 revision that makes 60k. Depends to your editing, it could be waste too much disk for sure. Actually it is not important either it waste too much disk or not. We should be able to delete post revisions anyway in my opinion.
Thoughts?
It is possible to hide revisions, look for the trash icon on the edit history dialog.
I don’t believe that is that @bek is asking. He mentioned disk usage, hiding a revision doesn’t do that, it just removes it from the client view for non-staff users.
That being said, I don’t believe this would be possible without accessing the database.
Yes, you right. I don’t talking about hiding revisions, I want to remove them. Who actually need a dozen of revision all the time? Don’t you think this is waste of resources @codinghorror ?
Anyway, as I said before take it waste or not, we should be able to remove these revisions… If there is no feature request like this, let me make one here 
(Forgive me if I say something rude, I’m not native speaker)
Also interested in this…
I wish there was a setting to disable the ability for the public to see revisions, as in, disable the pencil…
Is there a setting to turn off the ability to review past revisions?
Mahalo!
You’re looking for the edit history visible to public site setting. Disabling that will hide it.
Thanks, that did it!
It’s too bad it doesn’t remove the pencil too, but you’re right, it did disable the ability to click and view.
Mahalo!

您可以通过点击铅笔图标，然后逐一隐藏所有修订版本来将铅笔隐藏起来，但工作人员除外：
还需要将“对公众可见的编辑历史记录”设置也进行设置。
这个问题从未得到答复，但与帖子修订相关的磁盘或其他资源使用量可以忽略不计。
在快速发展的操作系统生态系统中，回应一篇 3 年前的帖子很少有用。
而且这也是自动三年晋升……可能不是个好主意的原因之一？
如果有人有足够强大的工具想把它移到别处并关闭这个话题，我完全没问题（而且我知道你们不需要我的许可 
这只是礼貌地告诉版主我们可能离题了）。
也许在没有回复的情况下自动删除帖子 x 年😂 这仍然是我一直不同意的一点。
总的来说，在网络论坛的使用中，我多年来从非常古老的帖子（以及非常古老的博客文章）中找到了许多解决方案，但也在那些帖子中发现了许多无用的臃肿和死胡同……用户和版主抱怨顶帖和/或不使用搜索，而不是保持帖子的质量或将其导向正题。
我们应该欢迎讨论，如果帖子不相关，它自然会湮没。
哎呀，编辑：
关于原始问题，对于任何通过搜索来到此帖的人：也许有，或者可能有一个插件来处理这个问题。（只保留最后 x 个修订版本）或者在管理面板中有一个官方设置来只保留最多 # 个修订版本。或者，删除 x 天前的修订版本。
如果此功能很重要，将来可能会实现。我们拭目以待。

以防将来有人有同样的问题并找到这个话题。
