Starting with Python 3.11, Pythons gzip might delegate to zlib.
Depending on the OS, i.e Ubuntu vs Fedora, the underlying zlib
implementation might differ, resulting in different output.
For now, or until a better solution exists, disable compression. This
results in the SDK increasing in size to ~157mb. Which is not
unreasonable, to regain determinism (and would be significantly worse
without the previous commit).

2594d5a189 build: Remove CMAKE_SKIP_BUILD_RPATH and SKIP_BUILD_RPATH settings (Henry Romp)
Pull request description:
Remove CMAKE_SKIP_BUILD_RPATH and SKIP_BUILD_RPATH settings that are no longer needed after reordering the Guix build script to perform binary checks after installation.
This PR also removes the unused CMake maintenance targets (`check-security` and `check-symbols`) and updates the Guix security checks to include binaries in the `libexec/` directory (added in PR #31679).

Also removes unused CMake maintenance targets (check-security and check-symbols) and updates security checks to include libexec/ directory binaries (see PR #31679).
This causes issues when building against newer glibcs (i.e 2.42), and isn't needed
in any case.

b4d0288c46 doc: update Guix INSTALL.md (fanquake)
Pull request description:
It's somewhat annoying that Guix is falling out of being packaged by distros. For some more context, see https://lwn.net/Articles/1035491/.
> However, it is likely that the [Guix](https://guix.gnu.org/en/) package manager will soon be removed from the repositories for Debian 13 and Debian 12 ("bookworm", also called oldstable).
This seems to be happening. You can't `apt install guix` using the current release of Debian. https://packages.debian.org/search?keywords=guix. Guix is not going to be included in next release of Ubuntu (`25.10`): https://packages.ubuntu.com/search?keywords=guix.
Looking at https://aur.archlinux.org/packages/guix, comments over the last few months seem to indicate that the build is broken.
A 1.5.0 release is planned for sometime in January 2026: https://codeberg.org/guix/release-planning/wiki/release-1.5.0-project/. So hopefully the situation is going to improve in future.

Pull request description:
5cb84f2013 isn't super recent, but it's enough to get access to some newer packages, such as LLVM 19, and avoids having to add any further work arounds for things that we know are fixed later (i.e nsis). Once things upstream have stabilized a bit more (the `core-updates` branch was fairly recently merged), we could look at bumping to something newer.
Package updates:
(base) glibc 2.35 -> 2.39
binutils 2.38 -> 2.41
diffutils 3.8 -> 3.10
gawk 5.2.1 -> 5.3.0
git-minimal 2.45.2 -> 2.46.0
grep 3.8 -> 3.11
gzip 1.12 -> 1.13
linux-headers 6.1.106 -> 6.1.119
make 4.3 -> 4.4.1
xz 5.2.8 -> 5.4.5
CMake 3.30 becomes available.
Clang/LLVM 19 becomes available.
Could be used for #32764.

Pull request description:
### Background
As part of the release process we often run *contrib/devtools/headerssync-params.py* and increase the values of the constants `HEADER_COMMITMENT_PERIOD` and `REDOWNLOAD_BUFFER_SIZE` in *src/headerssync.cpp* as per *doc/release-process.md* (example: 11a2d3a63e). This helps fine tune the memory consumption per `HeadersSyncState`-instance in the face of malicious peers.
(The `REDOWNLOAD_BUFFER_SIZE`/`HEADER_COMMITMENT_PERIOD` ratio determines how many Headers Sync commitment bits must match between PRESYNC & REDOWNLOAD phases before we start permanently storing headers from a peer. For more details see comments in *src/headerssync.h* and *contrib/devtools/headerssync-params.py*).
### Problem: Not feeding back headers until completing sync
During v30 release process #33274 made `REDOWNLOAD_BUFFER_SIZE` exceed the `target_blocks` constant used to control the length of chains generated for testing Headers Sync (`15000`, *headers_sync_chainwork_tests.cpp*).
The `HeadersSyncState::m_redownloaded_headers`-buffer now does not reach the `REDOWNLOAD_BUFFER_SIZE`-threshold during those unit tests. As a consequence `HeadersSyncState::PopHeadersReadyForAcceptance()` will not start feeding back headers until the PoW threshold has been met. While this will not cause the unit test to start failing on master, it means we have gone from testing behavior that resembles mainnet (way more than `REDOWNLOAD_BUFFER_SIZE` headers to reach the PoW limit), to behavior that is not possible/expected there.
### Solution
Avoid testing this unrealistic condition of completing Headers Sync before reaching `REDOWNLOAD_BUFFER_SIZE` by making tests able to define their own values through the new `HeadersSyncParams` instead of having them hard-coded for all chains & tests.
### Commits
* First 6 commits refactor and improve the unit tests in order to clarify latter changes.
* We then add checks for the behavior around the `REDOWNLOAD_BUFFER_SIZE` threshold.
* The main change: we extract the section from *headerssync.cpp* containing the constants to *kernel/chainparams.cpp*, making `HeadersSyncState` no longer hard-coded to mainnet.
### Notes
This PR used to be called "headerssync: Preempt unrealistic unit test behavior".

1aaaaa078b fuzz: Drop unused workaround after Apple-Clang bump (MarcoFalke)
fadad7a494 Drop support for EOL macOS 13 (MarcoFalke)
Pull request description:
Now that macOS 13 is EOL (https://en.wikipedia.org/wiki/MacOS_Ventura), it seems odd to still support it.
(macOS Ventura 13.7.8 received its final security update on 20 Aug 2025: https://support.apple.com/en-us/100100)
This patch will only be released in version 31.x, another 6 months out from now.
So:
* Update the depends build and release note template to drop EOL macOS 13.
* As a result, update the earliest Xcode to version 16 in CI.
* Also, bump the macOS CI runner to version 15, to avoid issues when version 14 will be at its EOL in about 1 year.
This also allows to drop a small workaround in the fuzz tests and unlocks libcpp hardening (https://github.com/bitcoin/bitcoin/pull/33462)

7b5261f7ef contrib: fix using macdploy script without translations. (amisha)
Pull request description:
**Description**
From what I deciphered reading the line https://github.com/bitcoin/bitcoin/blob/master/contrib/macdeploy/macdeployqtplus#L390 is that qt translations are optional to have hence we should be able to build without it but the case where the flag translations_dir falls back to its default Null value it raises this error.
The config comments also mentioned that adding translation file is optional.
```
./macdeployqtplus --help
usage: macdeployqtplus [-h] [-verbose [VERBOSE]] [-no-plugins] [-no-strip] [-translations-dir path] [-zip zip] app-bundle
Improved version of macdeployqt. Outputs a ready-to-deploy app in a folder "dist" and optionally wraps it in a .zip file. Note, that the "dist" folder will be deleted before deploying on each run. Optionally, Qt translation files
(.qm) can be added to the bundle.
```
**Steps to reproduce**
So I was following the general steps to set up app on macos however I didn't download any qt translations presuming it was optional from the comment linkedin in PR, so to reproduce if you have translation directories in place ull need to delete them and then try to build the file, otherwise don't download it at all and try to build it. It should fail on that flag as translations dir was never downloaded.
**Approach taken**
I have moved the code which adds language files under the if statement that first checks if the value of the flag is not Null before referencing it.

QT translations are optional, but the script would error when
'translations_dir' falls back to its default value NULL.
This PR fixes it by moving the set-up of QT translations under
the check for 'translations_dir' presence.

Move calculated constants from the top of src/headerssync.cpp into src/kernel/chainparams.cpp.
Instead of being hardcoded to mainnet parameters, HeadersSyncState can now vary depending on chain or test. (This means we can reset TARGET_BLOCKS back to the nice round number of 15'000).
Signet and testnets got new HeadersSyncParams constants through temporarily altering headerssync-params.py with corresponding GENESIS_TIME and MINCHAINWORK_HEADERS (based off defaultAssumeValid block height comments, corresponding to nMinimumChainWork). Regtest doesn't have a default assume valid block height, so the values are copied from Testnet 4. Since the constants only affect memory usage, and have very low impact unless dealing with a largely malicious chain, it's not that critical to keep updating them for non-mainnet chains.
