### explcheck v0.19.1

#### Fixes

This version of explcheck has fixed the following problems:

- Fix malformed context for issue E505 (Calling an undefined function).
  (reported by @muzimuzhi in #191, fixed in #193)

- Do not capture a newline after expl3-like material. (#193)

  This excludes the newline from the context messages and byte ranges for
  issues like E102 (Expl3 material in non-expl3 parts).

- Only put argument specifiers in the context of issue E201 (Unknown argument
  specifiers), not the whole control sequence name. (#193)

  This makes the context of issue E201 consistent with issue E427 (Comparison
  conditional without signature `:nnTF`).

- Fix the context of issue W200 ("Do not use" argument specifiers) missing
  characters when the name of the control sequence ends with double-superscript
  characters, like `\tex_let:^^44`. (#193)

- Report resolved control sequence names (like `\tex_let:D`) instead of the raw
  input text (like `\tex_let:^^44`) for issues W200 and W202 (Deprecated
  control sequences). (#193)

- Fix an incorrect assertion in code that reports issues E500 (Multiply defined
  function) and W501 (Multiply defined function variant). (reported by
  @muzimuzhi in #192, fixed in #194)

- Do not consider a definition being reached by itself a redefinition.
  (reported by @muzimuzhi in #192, fixed in #194)

  This prevents false positive detections of the issues E500 and W501.

- Do not report issue E505 (Calling an undefined function) when calling empty
  functions. (reported by @muzimuzhi in #192, fixed in #194)

- Weaken the confidence of incoming reaching definitions when the in-degree is
  greater than one. (reported by @muzimuzhi in #192, fixed in #194)

- Do not report issues for uninteresting macro-statements that are skipped
  during flow analysis and therefore have incomplete or unreliable information
  recorded. (#194)

- Only require definite reaching definitions for issues E500 and W501, not
  issues E504 (Function variant for an undefined function), E506 (Indirect
  function definition from an undefined function), and W507 (Setting a function
  before definition). (#194)

#### Continuous integration

This version of explcheck has made the following changes to our continuous
integration:

- Check issue context in tests. (reported by @muzimuzhi in #191, added in #193)
