，开源系统有写推送功能嘛？

sitemap.xml 中有一些连接是过期失效的，开源系统有写推送功能嘛？

sitemap.xml 如何生成？

哦哦，谢谢，v2.9.4 什么时候发布

请教一下，使用 injigen 主题的时候，点击首页的动态会报一个错误。我没有找到解决办法。、
[ERROR]-[2018-09-03 10:49:11]-[org.b3log.latke.servlet.renderer.freemarker.AbstractFreeMarkerRenderer:138]: FreeMarker renders error
FreeMarker template error:
An error has occurred when reading existing sub-variable "isReply"; see cause exception! The type of the containing value was: extended_hash+string (org.json.JSONObject wrapped into f.e.b.StringModel)

FTL stack trace ("~" means nesting-related):
- Failed at: #if comment.isReply != "" && comment... [in template "common-comment.ftl" at line 28, column 13]
- Reached through: #include "common-comment.ftl" [in template "dynamic.ftl" at line 44, column 17]

应该是前台退出后，后台再进行系统操作的时候不存在登录用户所以一直未响应吧！

某些模板切换不成功，某个模板返回动态页面的时候会报 500.（有没有交流群 = =～）

刚刚重新拷了一次源码，只是下载了依赖，什么都没有改动。
