　　ECL (Embeddable Common-Lisp) 是一个嵌入式的 Common-Lisp 语言解析器。
　　ECL 16.0.0 发布，此版本改进了现有 CL 库生态系统的各种互操作性，遵从 ANSI，提升跨平台的便捷性。
　　最显著的改进是提升常规代码质量 – 移除了死锁和接口，重构了部分代码库。同时还重做了测试框架，改进和更新了文档。
已知 issues

• 　　In Windows, ECL comes with the bytecode compiler by default,because C compilers are normally not available. Unfortunatelyseveral libraries out there are not prepared for this.  If youplan to use quicklisp and have a C compiler accessible to ECL,you may use (ext:install-c-compiler) to switch back to theLisp-to-C compiler.
  
• 　　In order to test a package, programmer has to install ECL on adesired destination (specified with "–prefix" parameter givento the configure script).
  

API 改进

• 　　There is no UFFI nickname for the FFI package - we piggyback oncffi-uffi-compat for UFFI dependent systems (our UFFI wasn'tversion 2.0 compatible and there were problems with ADSFdependencies on UFFI - it wasn't a system)
  
• 　　CLOS has the new nickname "MOP"
  
• 　　The new ext:run-program :error argument can automatically create aseparate stream if provided with the :stream keyword.The external-process structure also has a new field to hold thatstream.
  
• 　　ext:run-program accepts new arguments::if-input-does-not-exist,:if-error-exists,:external-format
  
• 　　ext:system no longer binds standard-input andstandard-output and now ignores input and output (useext:run-program for more control)
  
• 
  　　methods can be specialized on both single-float and double-float(built-in>
  
• 　　LET/FLET/LABELS will signal an error if the parameter of thesame name appears multiple times
  
• 　　lambda lists with repeated required parameters name areconsidered invalid
  
• 　　deprecated configure options "–with-system-boehm=x" and"–enable-slow-config" removed
  

功能增强

• 　　Verification if manual is up-to-date, providing corrections foroutdated parts
  
• 　　Documentation is now included in the main repository under thetop-level directory `doc'
  
• 　　Update libffi to version 3.2.1
  
• 　　Update asdf to version 3.1.5.4
  
• 　　Update Boehm-Demers-Weiser garbage collector to version 7.4.2
  
• 　　Pathname string-parts internal representation is now character, notbase-char
  
• 　　Dead code removal, tabulators were replaced by spaces
  
• 　　Better quality of generated code (explicit casting when necessary)
  

解决 issues 列表

• 　　Various fixes of bogus declarations
  
• 　　Remove deprecated GC calls
  
• 　　ROTATEF, SHIFTF, PSETF reworked to conform to the ANSI standard.Places were handled improperly in regard of multiple values.
  
• 　　Improved Unicode support in character handling
  
• 　　Format handles floats and exponentials correctly (major format rework)
  
• 　　Stack limits refinements and cleanup, inconsistency and bug fixes
  
• 　　Duplicate large block deallocation with GMP 6.0.0a fixed
  
• 　　ECL builds on OpenBSD with threads enabled
  
• 　　Closures put in mapcar work as expected in both compiled andinterpreted code
  
• 　　Improved readtable-case handling (:invert and character literals nowconform)
  
• 　　Library initialization functions have unique names - no risk ofclashing symbol names in object files
  
• 
  　　Format float bug fixed, when>
  
• 　　`logical-pathname-translations' now signals an error if logicalpathname wasn't defined yet, to conform with ANSI (it used toreturn NIL)
  
• 　　Wildcards in logical pathname translations are replaced correctly
  
• 　　Regression testing framework and unit tests cleanup
  
• 　　deftype ANSI conformity fix (deftype accepts macro labda-lists)
  
• 　　ECL built with MSVC doesn't crash when Control-C is pressed
  
• 　　Other minor tweaks
