Problems with Data Types, Medium Severity (1)

	Change	Effect
1	Field timestamp has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

history.h
[+] struct _hist_entry (1)

to the top

Problems with Symbols, Medium Severity (1)

	Change	Effect
1	This global data became non-const.	This data will be copied to applications at compile time. Any attempts to change this global data by library functions may result in crash of applications.

readline.h, libreadline.so.4.3
[+] rl_completer_word_break_characters [data] (1)

to the top

Problems with Data Types, Low Severity (1)

	Change	Effect
1	Size of this type has been changed from 8 bytes to 12 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

history.h
[+] struct _hist_entry (1)

to the top

Problems with Symbols, Low Severity (1)

	Change	Effect
1	Type of this global data has been changed from char const* to char*.	Replacement of data type may indicate a change in semantic meaning.

readline.h, libreadline.so.4.3
[+] rl_completer_word_break_characters [data] (1)

to the top

Other Changes in Constants (1)

	Change	Effect
1	The constant RL_STATE_TTYCSAVED with value 0x40000 has been added.	No effect.

readline.h
[+] RL_STATE_TTYCSAVED
