## 0.2.22

Relax text fixture to account for new `objectNotFoundError` error class.

## 0.2.21

R 4.6.0 makes `Rf_findVar*` inaccessible from package C code.  This update
replaces those uses with `R_getVar`.

## 0.2.20

R 4.6.0 makes `ATTRIB` inaccessible from package C code.  The following changes
stem from this:

* Replace `ATTRIB` usage with `R_getAttributes`, and adjust code for difference
  in return values between those two.
* `abstract.ts` now creates an R object with a "tsp_vetr" attribute to replace
  the "tsp" attribute in the template (see `?abstract`).
* Pairlist name error messages are slightly different.

Additionally:

* Fixed corner case bugs for e.g. `dimnames` with S4 attributes, and
* Refactored code to reduce probability of bugs like the above.

## 0.2.19

* Fix non C API access.
* [#109](https://github.com/brodieG/vetr/issues/109) fix namespaced function
  calls in template when the call does not reference `.`.
* Streamline vetting expression parsing.

## 0.2.17-18

* Fix bad C API accesses uncovered by new R-devel checks.

## 0.2.16

* Fix -Wformat warnings.

## 0.2.15

* [#109](https://github.com/brodieG/vetr/issues/109) allow for substituted
  arguments to contain objects (e.g. as might happen when a function is invoked
  with `do.call`).
* Address fun(void) declarations.
* Swap `snprintf` for `sprintf` (and fix off by one allocations).

## 0.2.14

* [#106](https://github.com/brodieG/vetr/issues/106) force promises prior to
  comparison to avoid accidentally accessing during comparisons.
* [#104](https://github.com/brodieG/vetr/issues/104) document need for
  `utils::globalVariables(".")`.
* Fix `grep` usage in tests for R 4.3 upcoming changes.
* Work-around `utf8toucs` issues on Solaris CRAN check farm.

## 0.2.13

* Tests no longer attempt to create S4 class definitions in base namespace.
* Fix UCRT warnings.

## 0.2.11-12

* [#102](https://github.com/brodieG/vetr/issues/102) `vetr()` now explicitly
  does not support vetting of `...`; previously it would allow it, but then fail
  ugly in internal code.
* [#100](https://github.com/brodieG/vetr/issues/100) Vetting expressions
  containing package qualified function calls (e.g. `base::sum(...)`) would
  fail.
* Update tests for new r-devel warnings for `sprintf`.

## 0.2.10

* Banish ghosts of `stringsAsFactors`.

## 0.2.9

* `stringsAsFactors` in tests explicitly set to TRUE due to r-devel change
  to the default.
* Addresss segfaults under gcc-10.0.1.  See discussion on
  [SO](https://stackoverflow.com/q/60406042/2725969).  Special thanks to Nate
  Eldredge for helping confirm this was indeed a [compiler
  bug](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93982).

## 0.2.8

* Correctly define/declare global symbols as per WRE 1.6.4.1, (h/t Professor
  Ripley, Joshua Ulrich for example fixes).

## 0.2.7

* Fix new `rchk` warnings.
* Set `RNGversion()` due to changes to sampling mechanism.

## 0.2.6

* [#96](https://github.com/brodieG/vetr/issues/96) Fix r-devel test failures
  that started with r75024.
* [#94](https://github.com/brodieG/vetr/issues/94) Properly credit `vapply` for
  template concept.

## 0.2.5

* Address CRAN warnings about packages used in tests not in suggests.

## 0.2.4

* As per [#93](https://github.com/brodieG/vetr/issues/93), ensure that attribute
  comparisons are always done in the same order.  We now sort the attribute
  lists prior to comparison.  This may result in slightly different output than
  previously as which attribute is declared incorrect or missing may change as a
  result of the sort since the first such attribute is reported.  Additionally,
  there is now more explicit handling of missing attributes so the error
  reporting for them will be slightly different.
* Fix memory problems reported by valgrind.

## 0.2.3

* [#92](https://github.com/brodieG/vetr/issues/92) `vetr` evaluated expressions
  in wrong environment.
* [#89](https://github.com/brodieG/vetr/issues/89) Zero length vetting token
  results pass; this is to align with `all(logical(0))` and consequently
  `stopifnot`.
* [#88](https://github.com/brodieG/vetr/issues/88) Extra space in deparsed
  vetted language.

## 0.2.2

* Test errors on Solaris.

## 0.2.1

* Fix Solaris compilation issue.
* Fix new `rcheck` warnings.
* Change R dependency to 3.3.2 to avoid problems with CRAN osx R-devel build.

## 0.2.0

* [#48](https://github.com/brodieG/vetr/issues/48): Implement `all_bw`, a
  more efficient version of `!anyNA(.) && all(. < x) && all(. > y)`.
* [#65](https://github.com/brodieG/vetr/issues/65)
  [#51](https://github.com/brodieG/vetr/issues/51): Check expressions that
  return character vectors will have part of the first element of that vector
  included in the error message.
* [#69](https://github.com/brodieG/vetr/issues/69): Vetting expressions that
  use the symbol of the object being vetted are no longer valid.  This avoid
  confusion caused by intended standard tokens being treated as template tokens
  because they use the object symbol instead of `.` to refer to the object.
* [#64](https://github.com/brodieG/vetr/issues/64): Rewrite result handling
  for multi token expressions to avoid unnecessary slow downs
* [#43](https://github.com/brodieG/vetr/issues/43): Fix rchck, rcnst, UBSAN,
  valgrind (ht @kalibera).
* [#76](https://github.com/brodieG/vetr/issues/76): Standardize defined
  terms (e.g. Standard vs Template Tokens)
* [#77](https://github.com/brodieG/vetr/issues/77): Replace `SIZE_T_MAX`
  with `SIZE_MAX` for portability
* [#70](https://github.com/brodieG/vetr/issues/70): Feedback from Richie
  Cotton and Michel Lang re: comparison "vignette"
* [#45](https://github.com/brodieG/vetr/issues/45): Cleanup error messages
  for objects that should be NULL.
* [#73](https://github.com/brodieG/vetr/issues/73): Cleaner protection stack
  handling
* [#56](https://github.com/brodieG/vetr/issues/56): Over-aggressive
  detection of infinite recursion in symbol substitution
* [#81](https://github.com/brodieG/vetr/issues/81): Remove test that attached
  attribute to symbol (illegal in R-devel now).
* [#59](https://github.com/brodieG/vetr/issues/59): Add a `CONTRIBUTING.md`
* Assorted typos (@franknarf1, @DasonK)

* [#39](https://github.com/brodieG/vetr/issues/39): `type_alike` return
  values structured like `alike`, doc fixes.

* [#36](https://github.com/brodieG/vetr/issues/36): Fix INTEGER C bug
* [#34](https://github.com/brodieG/vetr/issues/34): allow substitution of

  setting control.
