Announcement: Log4CL 1.1.0 - Logging library for Common Lisp

[Max Mikhanosha]

A new development version of Log4CL Common Lisp logging library had
been released on https://github.com/7max/log4cl

QuickLisp will continue to pull the "stable" version for a few months,
to give anyone enough time to check out the new version and migrate.

Major differences from the previous version are:

* Log4CL now includes Slime integration, which is available in a
package :log4slime. It provides log statement fortification in REPL,
ability to directly set log levels via right-click menu on the
category of the log message, and clicking on the log message going
to the source code for the log statement, and more.

* Default category separator changed to dot.

* The old CLOS method of setting option is depreciated in favor of new
(LOG:PACKAGE-OPTIONS) macro

* LOG package namespace was cleaned up, and its now an actual
package named LOG. The LOG4CL package is now nickname for
LOG4CL-IMPL

* Loggers now retain information about source file and package they
were instantiated from, with corresponding PATTERN-LAYOUT formats
to print them

As a consequence to pass a dynamically determined logger object to a
log statement, now requires (log:debug :logger
(form-that-returs-a-logger))

* (log:info a b c) and such now automatically do (log:expr) like processing
if they don't detect a format control string as first argument.

* Automatic category naming implemented on Clozure Common Lisp (CCL),
working exactly like SBCL one.

* Pattern layout extended with control of pretty printing and other enhancements

* Much more robust error handling in standard appenders, better reporting
of errors.

* It is possible to set a log level for the source file, it takes precedence
over the package category.

* On SBCL Log4CL hierarchy watcher thread that is used for flushing, a
is automatically terminated on exit, and before SAVE-LISP-AND-DIE.

* Added API to flush all appenders, LOG4CL:FLUSH-ALL-APPENDERS, which
is automatically called on SBCL from exit hooks. This prevents

* (LOG:CONFIG) now has many new pattern layout related options
:pretty, :nopretty, :file, :file2, :nofile, :time, :notime, :package
:nopackage, :ndc, :thread

These options change the built-in pattern used for :sane, :console
and other options that add new appender

* (LOG:CONFIG) with only the pattern options, will change existing console
appender instead of adding a new one.

* (LOG:CONFIG) appender displays a number next to each appender, and allows
removing of appenders via :REMOVE <n> option
