CQL version 6.1 release notesFor CQL version 6.1 features, see what's new in CQL 6.1. For CQL version 6.0.5, see CQL 6.0.5 documentation
CQL version 6.0.5 release notes
- We thank Robert Gamble generally for developing a meticulously programmed code suite, which has improve CQL greatly throughout.
- An command line option
-outputbufferhas been added. This option must be followed by a positive integer denoting the maximum number of bytes in a single output PGN game (the current default is 105000). This option is experimental and not supported.
- The two-piece-cycle.cql CQL file, which illustrates regular expression usage in line , was added to the examples.
CQL version 6.0.4 release notes
CQL version 6.0.3 release notes
- (bug fixes)
This version is primarily a bug-fix release. We thank Robert Gamble for his assistance with this release.
- When a transform's argument is a numeric filter, then the transform filter itself is numeric with value equal to the maximum of the values of the matching transforms of its argument.
- The transform documentation has been substantially rewritten. In addition to the introduction to transforms, there is now a more formal description. Each transform filter now has its own page.
- comment and message now accept filters that have no value as argument. If the filter has no value, then
<false>is output, depending on whether the filter matches. For example
comment ("check is: " check)
- max and min now accept more than two arguments.
- Some generic improvements to smart comments were made.
- Transform filters are more efficient in many cases, and are much better at avoiding the generation of redundant transforms.
- Transforms are now documented as supporting the
countkeyword. The use of range parameters to transform filters is now deprecated.
- The notransform filter was added.
currenttransformkeyword in message and comment was added.
CQL version 6.0.2 release notes
- persistent variables can be declared without assigning to them in their declaration.
- The experimental
-guipgnstdoutcommand line options have been added.
Release Notes for CQL version 6.0This table below is a partial list of changes from CQL version 5.2 to CQL version 6.0. It is not complete due to the large number of changes that were made.
We thank Robert Gamble for his assistance in finding and fixing numerous bugs in version 6.0.
Note that there were also some important changes from CQL version 5.1 to CQL version 5.2. If you are still using CQL version 5.1, read the release notes for CQL 5.2 before reading these release notes. CQL 6 also runs much faster than previous versions, particularly on complex CQL files. (On an 8-core machine, we typically see speedups of a factor of between 10 and 80 compared to CQL 5.2, depending on the exactly CQL file and PGN database). CQL 6 is also substantially more expressive and compact than previous versions of CQL.
