-queue.7
-    Alejandro Colomar
-        Create summary page for 'queue' APIs
-            The former queue(3) page was rather unwieldy, as it attempted to
-            describe too many APIs. After splitting that content out into a
-            number of smaller pages ( circleq.3, list.3, slist.3, stailq.3,
-            and tailq.3) move the much-reduced queue(3) page, which is now
-            essentially a summary of those APIs, from Section 3 to Section 7.

 Global changes
 --------------
 
-Various pages
-    Alejandro Colomar
-            Use ``sizeof`` consistently through all the examples in the
-            following way:
-
-            - Use the name of the variable instead of its type as argument for
-              ``sizeof``.
-
-Various pages
-    Alejandro Colomar
-        Use sizeof() to get buffer size (instead of hardcoding macro name)
-
-Various pages
-    Michael Kerrisk
-        Use \(aq instead of ' inside monospace fonts
-            Use \(aq to get an unslanted single quote inside monospace code
-            blocks. Using a simple ' results in a slanted quote inside PDFs.
-
-Various pages
-    Michael Kerrisk, Alejandro Colomar
-        Use C99 style to declare loop counter variables
-            Rather than:
-
-                sometype x;
-
-                for (x = ....; ...)
-
-            use
-
-                for (sometype x = ...; ...)
-
-            This brings the declaration and use closer together (thus aiding
-            readability) and also clearly indicates the scope of the loop
-            counter variable.
-
-Various pages
-    Alejandro Colomar
-        Switch printf() casts to use [u]intmax_t + %ju / %jd
-            Let's move to the 21st century. Instead of casting system data
-            types to long/long long/etc. in printf() calls, instead cast to
-            intmax_t or uintmax_t, the largest available signed/unsigned
-            integer types.
-
-Various pages
-    Alejandro Colomar
-        Omit 'int' keyword for 'short', 'long' and 'long long' types
-
-Various pages
-    Alejandro Colomar
-        Remove unneeded casts
-
-Various pages
-    Alejandro Colomar
-        In printf(): s/0x%/%#/ except when followed by X instead of x
-            Use printf()'s '#' flag character to prepend the string "0x".
-
-            However, when the number is printed in uppercase, and the prefix
-            is in lowercase, the string "0x" needs to be manually written.
-
-Various pages
-    Michael Kerrisk
-        Use C99-style declarations for readability
-            Rather than writing things such as:
-
-                struct sometype *x;
-                ...
-                x = malloc(sizeof(*x));
-
-            let's use C99 style so that the type info is in the same line as
-            the allocation:
-
-                struct sometype *x = malloc(sizeof(*x));
-
-Various pages
-    Alejandro Colomar
-        Cast to 'unsigned long' rather than 'long' when printing with "%lx"
-
-stdarg.3
-    Alejandro Colomar
-        Declare variables with different types in different lines
-        In particular, don's mix a variable and a pointer declaration
-        on the same line: TYPE x, *p;
-
 
 Changes to individual pages
 ---------------------------
 
-memusage.1
-    Michael Kerrisk
-        EXAMPLES: remove doubled calculations
-            The same calculations are repeated in malloc() and printf() calls.
-            For better readability, do the calculations once.
-    Michael Kerrisk
-        Use %zu rather than %zd when printing 'size_t' values
-
-clock_getres.2
-    Alejandro Colomar
-        EXAMPLES: use 'const' when appropriate
-    Alejandro Colomar  [Jakub Wilk]
-        Cast 'time_t' to 'int' for printf() and fix the length modifiers
-    Michael Kerrisk  [Tony May]
-        Fix type and variable name in dynamic clock code example
-
-clone.2
-    Michael Kerrisk
-        CAP_CHECKPOINT_RESTORE can now be used to employ 'set_tid'
-
-epoll_ctl.2
-    Michael Kerrisk
-        epoll instances can be nested to a maximum depth of 5
-            This limit appears to be an off-by-one count against
-            EP_MAX_NESTS (4).
-    Michael Kerrisk
-        Move some version info from CONFORMING TO to VERSIONS
-

-
-mprotect.2

-
-mq_getsetattr.2

-        Use 'const' when appropriate
-
-msgop.2
-    Yang Xu

-    Michael Kerrisk  [henrik@optoscale.no]
-        ERRORS: add EBUSY
-
-openat.2
-    Alejandro Colomar
-        SYNOPSIS: return long
-            The Linux kernel uses long as the return type for this syscall.
-            As glibc provides no wrapper, use the same type the kernel uses.
-
-open_by_handle_at.2
-    Alejandro Colomar
-        Use "%u" rather than "%d" when printing 'unsigned int' values

-        Update to include changed size semantics
-
-seccomp.2
-    Michael Kerrisk  [Jann Horn]
-        Warn reader that SECCOMP_RET_TRACE can be overridden
-            Highlight to the reader that if another filter returns a
-            higher-precedence action value, then the ptracer will not
-            be notified.
-    Michael Kerrisk  [Rich Felker]
-        Warn against the use of SECCOMP_RET_KILL_THREAD
-            Killing a thread with SECCOMP_RET_KILL_THREAD is very likely
-            to leave the rest of the process in a broken state.
-    Michael Kerrisk  [Rich Felker]
-        EXAMPLES: use SECCOMP_RET_KILL_PROCESS rather than SECCOMP_RET_KILL
-    Alejandro Colomar
-        Use ARRAY_SIZE() macro instead of raw sizeof division

-        Move system calls from discontinued ports out of main syscall list
-            Various ports that had their own indigenous system calls have
-            been discontinued. Remove those system calls (none of which had
-            manual pages!) to a separate part of the page, to avoid
-            cluttering the main list of system calls.
-    Michael Kerrisk
-        Add close_range (Linux 5.9)
-
-timerfd_create.2
-    Alejandro Colomar
-        Use 'PRIxN' macros when printing C99 fixed-width integer types

-        Use 'PRIx64' rather than "%llx" when printing 64-bit fixed-width types
-
-argz_add.3
-envz_add.3
-    Michael Kerrisk  [Jonny Grant]
-        Point out that 'error_t' is an integer type
-
-bsearch.3
-    Alejandro Colomar
-        Fix intermediate type and remove unneeded casts
-
-bswap.3
-    Jakub Wilk
-        Use strtoull() for parsing 64-bit numbers
-
-dlopen.3
-    Michael Kerrisk
-        Clarify DT_RUNPATH/DT_RPATH details
-            It is the DT_RUNPATH/DT_RPATH of the calling object (not the
-            executable) that is relevant for the library search. Verified
-            by experiment.
-
-errno.3

-    Michael Kerrisk
-        Under CAP_SYS_ADMIN, group "sub-capabilities" together
-            CAP_BPF, CAP_PERFMON, and CAP_CHECKPOINT_RESTORE have all been
-            added to split out the power of CAP_SYS_ADMIN into weaker pieces.
-            Group all of these capabilities together in the list under
-            CAP_SYS_ADMIN, to make it clear that there is a pattern to these
-            capabilities.
-    Michael Kerrisk
-        CAP_SYS_ADMIN implies CAP_CHECKPOINT_RESTORE
-            But the latter, weaker capability is preferred.

+
+New and rewritten pages
+-----------------------
+
+circleq.3
+    Alejandro Colomar
+        New page with 'circleq' content extracted from queue(3)
+
+list.3
+    Alejandro Colomar
+        New page with 'list' content extracted from queue(3)
+
+
+pthread_attr_setsigmask_np.3
+    Michael Kerrisk
+        New page for pthread_attr_setsigmask_np() + pthread_attr_getsigmask_np()
+            Add a page documenting the pthread_attr_setsigmask_np(3) and
+            pthread_attr_getsigmask_np(3) functions added in glibc 2.32.
+
+slist.3
+    Alejandro Colomar
+        New page with 'slist' content extracted from queue(3)
+
+stailq.3
+    Alejandro Colomar
+        New page with 'stailq' content extracted from queue(3)
+
+tailq.3

+
+queue.7
+    Alejandro Colomar
+        Create summary page for 'queue' APIs
+            The former queue(3) page was rather unwieldy, as it attempted to
+            describe too many APIs. After splitting that content out into a
+            number of smaller pages ( circleq.3, list.3, slist.3, stailq.3,
+            and tailq.3) move the much-reduced queue(3) page, which is now
+            essentially a summary of those APIs, from Section 3 to Section 7.

+Global changes
+--------------
+
+Various pages
+    Alejandro Colomar
+            Use ``sizeof`` consistently through all the examples in the
+            following way:
+
+            - Use the name of the variable instead of its type as argument for
+              ``sizeof``.
+
+Various pages
+    Alejandro Colomar
+        Use sizeof() to get buffer size (instead of hardcoding macro name)
+
+Various pages
+    Michael Kerrisk
+        Use \(aq instead of ' inside monospace fonts
+            Use \(aq to get an unslanted single quote inside monospace code
+            blocks. Using a simple ' results in a slanted quote inside PDFs.
+
+Various pages
+    Michael Kerrisk, Alejandro Colomar
+        Use C99 style to declare loop counter variables
+            Rather than:
+
+                sometype x;
+
+                for (x = ....; ...)
+
+            use
+
+                for (sometype x = ...; ...)
+
+            This brings the declaration and use closer together (thus aiding
+            readability) and also clearly indicates the scope of the loop
+            counter variable.
+
+Various pages
+    Alejandro Colomar
+        Switch printf() casts to use [u]intmax_t + %ju / %jd
+            Let's move to the 21st century. Instead of casting system data
+            types to long/long long/etc. in printf() calls, instead cast to
+            intmax_t or uintmax_t, the largest available signed/unsigned
+            integer types.
+
+Various pages
+    Alejandro Colomar
+        Omit 'int' keyword for 'short', 'long' and 'long long' types
+
+Various pages
+    Alejandro Colomar
+        Remove unneeded casts
+
+Various pages
+    Alejandro Colomar
+        In printf(): s/0x%/%#/ except when followed by X instead of x
+            Use printf()'s '#' flag character to prepend the string "0x".
+
+            However, when the number is printed in uppercase, and the prefix
+            is in lowercase, the string "0x" needs to be manually written.
+
+Various pages
+    Michael Kerrisk
+        Use C99-style declarations for readability
+            Rather than writing things such as:
+
+                struct sometype *x;
+                ...
+                x = malloc(sizeof(*x));
+
+            let's use C99 style so that the type info is in the same line as
+            the allocation:
+
+                struct sometype *x = malloc(sizeof(*x));
+
+Various pages
+    Alejandro Colomar
+        Cast to 'unsigned long' rather than 'long' when printing with "%lx"
+
+stdarg.3
+    Alejandro Colomar
+        Declare variables with different types in different lines
+        In particular, don's mix a variable and a pointer declaration
+        on the same line: TYPE x, *p;
+
+
+Changes to individual pages
+---------------------------
+
+memusage.1
+    Michael Kerrisk
+        EXAMPLES: remove doubled calculations
+            The same calculations are repeated in malloc() and printf() calls.
+            For better readability, do the calculations once.
+    Michael Kerrisk
+        Use %zu rather than %zd when printing 'size_t' values
+
+clock_getres.2
+    Alejandro Colomar
+        EXAMPLES: use 'const' when appropriate
+    Alejandro Colomar  [Jakub Wilk]
+        Cast 'time_t' to 'int' for printf() and fix the length modifiers
+    Michael Kerrisk  [Tony May]
+        Fix type and variable name in dynamic clock code example
+
+clone.2
+    Michael Kerrisk
+        CAP_CHECKPOINT_RESTORE can now be used to employ 'set_tid'
+
+epoll_ctl.2
+    Michael Kerrisk
+        epoll instances can be nested to a maximum depth of 5
+            This limit appears to be an off-by-one count against
+            EP_MAX_NESTS (4).
+    Michael Kerrisk
+        Move some version info from CONFORMING TO to VERSIONS
+
+eventfd.2
+    Alejandro Colomar
+        Use 'PRIxN' macros when printing C99 fixed-width integer types
+
+futex.2
+    Alejandro Colomar
+        Use appropriate types
+
+getdents.2
+    Alejandro Colomar

+
+intro.2
+intro.3
+credentials.7
+feature_test_macros.7
+standards.7
+    Michael Kerrisk
+        SEE ALSO: add system_data_types(7)
+
+ioctl_ns.2
+stat.2
+    Alejandro Colomar  [Konstantin Bukin]
+        Fix signedness of printf specifiers
+
+membarrier.2
+    Alejandro Colomar
+        Note that glibc does not provide a wrapper
+
+mprotect.2
+    Alejandro Colomar
+        Use "%p" rather than casting to 'long' when printing pointer values
+
+mq_getsetattr.2
+    Alejandro Colomar
+        Use 'const' when appropriate
+
+msgop.2
+    Yang Xu
+        Add restriction on ENOSYS error
+
+open.2
+    Michael Kerrisk  [henrik@optoscale.no]
+        ERRORS: add EBUSY
+
+openat.2
+    Alejandro Colomar
+        SYNOPSIS: return long
+            The Linux kernel uses long as the return type for this syscall.
+            As glibc provides no wrapper, use the same type the kernel uses.
+
+open_by_handle_at.2
+    Alejandro Colomar
+        Use "%u" rather than "%d" when printing 'unsigned int' values
+
+perf_event_open.2
+    Alexey Budankov
+        Update the man page with CAP_PERFMON related information
+
+recv.2
+send.2
+    Michael Kerrisk
+        Add cross references to pages with further info about ancillary data
+
+sched_getattr.2
+    Aleksa Sarai
+        Update to include changed size semantics
+
+seccomp.2
+    Michael Kerrisk  [Jann Horn]
+        Warn reader that SECCOMP_RET_TRACE can be overridden
+            Highlight to the reader that if another filter returns a
+            higher-precedence action value, then the ptracer will not
+            be notified.
+    Michael Kerrisk  [Rich Felker]
+        Warn against the use of SECCOMP_RET_KILL_THREAD
+            Killing a thread with SECCOMP_RET_KILL_THREAD is very likely
+            to leave the rest of the process in a broken state.
+    Michael Kerrisk  [Rich Felker]
+        EXAMPLES: use SECCOMP_RET_KILL_PROCESS rather than SECCOMP_RET_KILL
+    Alejandro Colomar
+        Use ARRAY_SIZE() macro instead of raw sizeof division
+
+setns.2
+    Michael Kerrisk
+        Correct the version for time namespace support
+
+sigaction.2
+    Michael Kerrisk  [Alejandro Colomar]
+        Use correct POSIX type for siginfo_t.si_value
+
+syscalls.2
+    Michael Kerrisk
+        Move system calls from discontinued ports out of main syscall list
+            Various ports that had their own indigenous system calls have
+            been discontinued. Remove those system calls (none of which had
+            manual pages!) to a separate part of the page, to avoid
+            cluttering the main list of system calls.
+    Michael Kerrisk
+        Add close_range (Linux 5.9)
+
+timerfd_create.2
+    Alejandro Colomar
+        Use 'PRIxN' macros when printing C99 fixed-width integer types
+
+userfaultfd.2
+    Michael Kerrisk
