14) 2017.12.22
14.1) bugfix: master_conf.cpp 中 master_add_service 在调用 acl_master_ent_find
时，应该使用 entry->conf (配置文件路径) 而不是 entry->path 程序路径
14.2) bugfix: master_api.cpp 远程调用 restart 命令时，没有重新读取配置文件，
所以造成无法启动服务程序改名后的服务

13) 2017.11.21
13.1) feature: add master_config command for getting the configure of master

12) 2017.11.12
12.1) bugfix: master should not fork child process after starting service failed.

11) 2017.11.11
11.1) feature: master can start services which are specified in file.

10) 2017.11.7
10.1) feature: master can start one service with the specified path

9) 2017.10.26
9.1) feature: when starting one or more services remotely, sync or async can be used.

8) 2017.9.22
8.1) workaround: restructure the manage module of acl_master.

7) 2017.9.9
7.1) feature: master can wait callback from children when reloading the specific children

6) 2017.9.5
6.1) feature: master can wait children to exit with sync or async
6.2) feature: master can kill SIGTERM children when reloading
6.3) bugfix: master_params.cpp 中的 init_conf_str_vars 函数在 master reload 时
有内存泄露

5) 2017.8.11
5.1) safety: master can't fatal for some configure error of any app service.

4) 2017.7.7
4.1) feature: master can stop or kill one service, stopping service is graceful
by closing the IPC pipe, and killing service is rude by signal SIGTEM children.
4.2) feature: add graceful stop API in master's web management interface.

3) 2017.6.26
3.1) protocol: changed the web management protocols.

2) 2017.6.25
2.1) feature: acl_master uses kernel event mode

1) 2017.6.18
1.1) feature: In Docker's running time, the master's pid was set to 1; When
stopping master by sending TERM singal to master's pid, master_sigdeath func
will be called and which'll send TERM to -pid that's the master's pid group,
but in docker the pid is 1, so we should stop the children in the other way.
