## Change log

* Version 2.1 (this)
    - fixing `show_def` and `show_term`, fixing [\#9](https://github.com/alceu-frigeri/starray/issues/9)
    - using tokglobalstack (while iterating)

* Version 2.0
    - full re-factoring, based on _base_st, _term_st and _ref_st (better context control, lesser use of cs-names)
    - new package option: iter cascade
    - added series of _iparsed commands (alike _uparsed ones) for iterate_over
    - code cleanup: removing redundant tmp variables and no longer need lkernel3 variants.
    - readme fix (hash marks).
    - documentation update
    
* Version 1.12a
    - using ```\pkginfograbProvidesExplPackage```
    - internals: better expansion  control. Reduced dependency on internal variables context
    - deprecation: all commands related to user saved references renamed, to avoid name crashing
    - new package option to easy the commands `migration`
    - removed a package option: prefix

* Version 1.11
    - code cleanup (variants) and a bit of optimization
    - removing references to expl scratch variables (like `\l_tmpa_tl`, `\l_tmpa_int`...) 
    - deprecating `\starray_term_syntax:` in favour of `\starray_term_parser:` (issues  warnings)
    - added a new set of \starray_parsed_ commands
    - re-factoring the `parsed` commands generation
    - using `pkginfograb` for package's info


* Version 1.10
    - fixing issue [\#8](https://github.com/alceu-frigeri/starray/issues/8).
    - typos in documentation
    - an example of use added (finally 'fixing' [\#5](https://github.com/alceu-frigeri/starray/issues/5)),
      in [demo](https://github.com/alceu-frigeri/starray/tree/main/demo)
    
* Version 1.9b
    - fixing issue [\#7](https://github.com/alceu-frigeri/starray/issues/7) 
      ( related to [\#1189](https://github.com/latex3/latex3/issues/1189) ) 
      and removing the (unneeded) ```predicate``` in variant generation of ``` \starray_(g)set_prop:nnn```.

* Version 1.9 
    - Removing some internal structures (_base_prop, _def_prop) deprecated by the last three updates.

* Version 1.8
    - code speedup thanks to 'linked' property lists. Code now relies on a more recent l3kernel.

* Version 1.7
    - code cleanup. Still related to issues: [\#6](https://github.com/alceu-frigeri/starray/issues/6), 
      [\#1460](https://github.com/latex3/latex3/issues/1460) and 
      [\#1466](https://github.com/latex3/latex3/issues/1466)
    - documented \starray_get_uniqueID (helper function, see documentation)

* Version 1.6
    - removing all V-expansion of property/sequence lists to avoid further issues with l3kernel 
      issues: [\#6](https://github.com/alceu-frigeri/starray/issues/6), 
      [\#1460](https://github.com/latex3/latex3/issues/1460) and 
      [\#1466](https://github.com/latex3/latex3/issues/1466)
    - Remarks: code is operational but needs further cleanup!

* Version 1.5
    - added \starray_term_syntax:nNN variant and friends (\starray_parsed_ ... :NN ) the _parsed_ ones being expandable

* Version 1.4
    - added a few functions _set_iter_from_hash:nn and _iterate_over:n.

* Version 1.3 
    - Fixed issue [\#4](https://github.com/alceu-frigeri/starray/issues/4), where (in some instances) _set_from_keyval could render a quark loop.

* Version 1.2
    - Issues [\#3](https://github.com/alceu-frigeri/starray/issues/3)
    - added expandable versions of some commands (see manual)
    - documentation

* Version 1.1
    - Issues [\#1](https://github.com/alceu-frigeri/starray/issues/1)/[\#2](https://github.com/alceu-frigeri/starray/issues/2)
    - most/all commands are protected now
    - removed predicate version of conditionals
    - documentation


* Version 1.0
    - Initial release  by CTAN.
