Fedora Linux 45 will be formally released on Tuesday, 3 November, according to Phoronix, which reported that the distribution is ready to ship and that the final release is now just days away.
The date caps the usual Fedora release cycle: a beta period, a freeze on major package updates, and a final push to polish the desktop and toolchain stacks before the code is declared stable. Exact version numbers for the kernel, GNOME, KDE Plasma and GCC in Fedora 45 have not been confirmed in the reporting so far — those details are expected to be published alongside the official release notes when the distribution goes gold.
What's landing
As with recent Fedora releases, the headline changes centre on the desktop and core toolchain. Fedora's policy is to carry the current upstream releases of GNOME and KDE Plasma, plus a recent Linux kernel and compiler toolchain, so Fedora 45 is expected to be one of the first mainstream distributions to ship this cycle's desktop releases out of the box.
Fedora Workstation continues to target GNOME as its default experience, while the KDE Plasma spin remains available for users who prefer that stack. Beyond the desktop, Fedora has historically been the upstream proving ground for changes that later propagate to Red Hat Enterprise Linux and its derivatives — a point worth noting for anyone tracking where RHEL-bound technology comes from.
Upgrading
Fedora's standard in-place upgrade path is dnf system-upgrade, which downloads and stages the new release while the system is still running, then reboots into the transaction. GNOME Software also offers a graphical upgrade route for Workstation users.
Conventional Fedora practice — and the guidance that applies to Fedora 45 in the absence of anything to the contrary — is to wait a short while after general availability before upgrading production or business-critical machines. Early post-release days sometimes surface packaging regressions, mirror load or third-party repository conflicts (particularly RPM Fusion and vendor-provided GPU or conferencing packages). Users who prefer to avoid that entirely can do a clean install, which remains the simplest path for machines where local configuration is easy to rebuild.
Who should be watching
Fedora occupies an unusual position in the ecosystem: it is the community distribution that sits directly upstream of Red Hat Enterprise Linux, and its release content often previews what will eventually land in RHEL and CentOS Stream. For administrators and packagers working in RHEL-adjacent environments, Fedora 45 is a useful early read on what the enterprise line may pick up over the next cycle.
It is also the point where new packaging conventions, systemd revisions and compiler defaults become broadly visible — meaning the post-GA window after 3 November is typically when downstream rebuilds and third-party packagers start adapting. Anyone maintaining Fedora-based infrastructure, or tracking upstream changes that feed into RHEL estates, will find the release notes worth a look once they are published.
The date to watch is 3 November, when Fedora 45's final package set, release notes and download images go live. Reporting by Phoronix on the schedule is available at phoronix.com.
據 Phoronix 報導，Fedora Linux 45 將於 11 月 3 日（星期二）正式發布。該報導指發行版已準備就緒，最終版本距離推出僅剩數日。
此日期為 Fedora 一貫的發布週期畫上句號：包括 beta 測試期、主要套件更新凍結，以及在程式碼宣告穩定之前對桌面環境及工具鏈作最後一輪完善。截至目前的報道，Fedora 45 中 Linux kernel、GNOME、KDE Plasma 及 GCC 的確切版本號尚未確認——這些細節預計將隨官方 release notes 一同在發行版正式推出時公布。
主要變更內容
與近期的 Fedora 發布一樣，重點改動集中於桌面環境及核心工具鏈。Fedora 的政策是採用 GNOME 及 KDE Plasma 的最新上游版本，以及較新的 Linux kernel 和編譯器工具鏈，因此 Fedora 45 預計將是首批開箱即搭載本週期桌面環境正式版本的主流發行版之一。
Fedora Workstation 繼續以 GNOME 作為預設體驗，而 KDE Plasma 版本則繼續提供予偏好該技術組合的用戶。除桌面環境外，Fedora 一直是上游測試場，多項改動先在此驗證，其後才推廣至 Red Hat Enterprise Linux 及其衍生版本——這一點值得任何追蹤 RHEL 相關技術來源的人士留意。
升級方式
Fedora 的標準就地升級途徑是 dnf system-upgrade，該指令會在系統仍在運行期間下載並準備新版本，隨後重新啟動完成升級程序。GNOME Software 亦為 Workstation 用戶提供圖形化升級途徑。
Fedora 的慣常做法——以及在沒有相反指示下適用於 Fedora 45 的指引——是於正式發行（general availability）後等待一段短時間，才升級生產或業務關鍵機器。發布後的最初數日有時會出現 packaging regression（套件回歸錯誤）、鏡像站負載過高或第三方 repository 衝突（尤其涉及 RPM Fusion 及廠商提供的 GPU 或視像會議套件）。希望完全避開這些問題的用戶可以進行全新安裝；對於本機配置容易重建的機器，這仍是最簡單的途徑。
哪些人士需要留意
Fedora 在生態系統中佔據一個獨特位置：它是直接處於 Red Hat Enterprise Linux 上游的社群發行版，其發布內容往往預示日後將納入 RHEL 及 CentOS Stream 的功能。對於在 RHEL 相關環境中工作的管理員及 packager 而言，Fedora 45 是了解企業級產品線下一個週期可能引入哪些技術的有用早期參考。
它同時是新的 packaging 慣例、systemd 修訂版本及編譯器預設值開始廣泛為人所知的節點——這意味著 11 月 3 日之後的 GA 後期，通常是下游重新建置及第三方 packager 開始作出適應的時候。任何維護 Fedora 基礎設施，或追蹤流入 RHEL 系統的上游變更的人士，在 release notes 發布後都值得一看。
需要留意的日期是 11 月 3 日，屆時 Fedora 45 的最終套件組合、release notes 及下載映像將同步上線。Phoronix 對此時間表的報導可參閱 phoronix.com。
