logback 1.0.10 发布了，Logback是由log4j创始人设计的又一个开源日志 组件。logback当前分成三个模块：logback-core,logback- classic和logback-access。logback-core是其它两个模块的基础模块。logback-classic是log4j的一个 改良版本。此外logback-classic完整实现SLF4J API使你可以很方便地更换成其它日志系统如log4j或JDK14 Logging。logback-access访问模块与Servlet容器集成提供通过Http来访问日志的功能。
主要改进记录包括：
Upgraded the (optional) groovy dependency to version 2.0.7 (from 2.0.0).
The logger cache field in LoggerContext now uses a ConcurrentHashMap instead of a regular HashMap. This dramatically improves the speed of logger retrieval and incidentally fixes LOGBACK-142.
In SyslogAppender allow suffixPattern to begin with literal text. This issue was reported Bruno Polaco in LOGBACK-782 who also provided the relevant patch.
In order to reduce unnecessary boilerplate several common types and packages are now imported automatically. This feature was contributed by Joris Kuipers.
Computation of caller information now takes into account Groovy frames (if nunning under Groovy). This fixes LOGBACK-811.
