documented in this file.

## [Unreleased] ##
- Added command-line option `l` (Display the legal notice and exit.)
- Fixed unusual struct allocations.
- Made functions and variables private where possible.
- Replaced `bcopy()` with `memmove()`.
- Replaced calls to `rand()` with `brand()` which uses
  `arc4random_uniform()`.
- Replaced unbounded string handling functions. Multiple occurrences.

## [1.4.1] - 2024-05-26 ##
- **Added** command-line option `a` to the addplayer program. If given, it
  adds a player with admin privileges.
- **Added** usage of `time_t`.
- **Fixed** out of bounds array access in `match_command()`.
- **Fixed** resource leaks, i.e. missing calls to `fclose()`.
- **Fixed** usage of possibly uninitialized variables.

## [1.4] - 2024-05-20 ##
- **Added** usage of `time_t`. Multiple occurrences.
- **Changed** the program to create news index files even if no old ones
  are existent on the disk.
- **Fixed** clang warnings.
- **Fixed** sign compare (`-Wsign-compare`). Multiple occurrences.
- **Reformatted code** according to OpenBSD's KNF. Whole tree completed.
- **Replaced** unbounded string handling functions.

## [1.3] - 2024-05-05 ##
- **Added** parameter lists to many function declarations.
- **Added** usage of `ARRAY_SIZE()`.
- **Added** usage of `reallocarray()`. Multiple occurrences.
- **Added** usage of the functions from `err.h`.
- **Changed** the make install target to not overwrite the data messages
  in case they're already present.
- **Deleted** unused includes.
- **Fixed** passing argument 2 of `ReadGameAttrs()` from incompatible
  pointer type in `jsave_history()`.
- **Made** functions and variables private where possible.
- **Reformatted code** according to OpenBSD's KNF:
  - `algcheck.c`
  - `command.c`
  - `gamedb.c`
  - `movecheck.c`
  - `obsproc.c`
  - `talkproc.c`
  - ...
- **Replaced** unbounded string handling functions. _Multiple_
  occurrences.

## [1.2] - 2024-04-14 ##
- **Added** parameter lists to many function declarations.
- **Added** usage of `reallocarray()` which handles multiplication
  overflow.
- **Added** usage of `msnprintf()`, `mstrlcpy()` and `mstrlcat()` which
  detects and logs truncation.
- **Added** usage of the functions from `err.h`.
- **Checked out** the following files by tag 1.0, because the previous
  changes made to them possibly introduced game bugs:
  - `algcheck.c`
  - `algcheck.h`
  - `board.c`
  - `movecheck.c`
  - `movecheck.h`
- **Cleared** sensitive data with `explicit_bzero()`.
- **Fixed** an empty hostname in the addplayer program.
- **Fixed** bogus type for storing the return value of `time()`. It should
  really be `time_t`. Multiple occurrences.
- **Fixed** non-ANSI function declarations of functions. (Multiple
  occurrences.)
- **Made** functions and variables private where possible.
- **Reformatted code** according to OpenBSD's KNF:
  - `ratings.c`
  - `variable.c`
  - ...
- **Replaced** unbounded string handling functions. _Multiple_
  occurrences.

## [1.1] - 2024-03-30 ##
- **Added** `PRINTFLIKE()` and fixed many format errors.
- **Added** argument lists to many function declarations.
- **Added** initialization of many variables.
- **Added** newly written manual pages.
- **Added** usage of `ARRAY_SIZE()`
- **Changed** the addplayer program to generate passwords that are 8
  characters long (was 4).
- **Deleted** non-existent functions from the header files.
- **Deleted** obsolete and unused code
- **Deleted** unused includes.
- **Fixed** format strings that weren't string literals. Potentially
  insecure. (_Multiple_ occurrences.)
- **Fixed** incorrect buffer sizes
- **Fixed** unchecked return values
- **Made** functions and variables private (aka static) where possible.
- **Marked** functions that doesn't return `__dead`.
- **Marked** unused function parameters.
- **Redefined** `ASSERT()`
- **Reformatted code** according to OpenBSD's KNF.
- **Replaced** `rand()` calls with arc4random.
- **Replaced** _multiple_ `sprintf()` calls with `snprintf()` + truncation
  checks.
- **Replaced** _multiple_ occurrences of `strcpy()` and `strcat()` with
  size-bounded versions.
- **Switched to** the usage of the functions from `err.h` in multiple
  places for error handling.

## [1.0] - 2023-12-28 ##
- Added a new build system (and deleted the old).
- Added argument lists to many function declarations.
- Added auto-generation of the header file `ficspaths.h` and included
  it in `config.h`.

  of `int`.
