December 31, 2026 End-of-Life Day: PHP 8.2, Spring Boot 4.0 and More

By Scott Bissett  ·  Published: October 11, 2026  ·  EOL Watch — deadline analysis  ·  Every date on this page is served from our data layer, which is re-read against each vendor's own source at every build; upgrade targets are the ones named in our existing guides and product notes, not ours.

More dated lifecycle milestones land on December 31, 2026 than on any other day of our 2026 calendar. The reason is mundane: PHP, Spring, Oracle, Cloudera, SAP, Micrometer and kernel.org all publish support windows by month, and a window that ends "December 2026" is served, under each vendor's own last-day convention, as the last day of December. The result is one date shared by a web runtime, a Java application stack, five Oracle middleware products, a Microsoft server, two hyperconverged-platform releases, an enterprise Linux service pack, a Kubernetes distribution, a Hadoop platform, a print server, four NAS models, a line of access points, a reporting suite, two kernel branches and a service mesh. One day later, on January 1, 2027, Oracle Solaris 10 and 11.3 leave Extended Support and four Check Point Scalable Platform models leave engineering support. This page is the hub for the day: every row we serve, its date as served, and where each vendor or our existing guide says to go. The detail lives in the per-product guides linked from each section.

Why one day carries so much

Most of the rows on this page share the date because of how their vendors write policy, not because anything was coordinated. Every PHP branch we serve ends its active and security phases on a December 31. Spring's generations table (the data behind spring.io's support pages for Spring Boot, Spring Security, Spring Cloud and Micrometer) states every open-source and commercial end as the last day of a month. Oracle's Fusion Middleware Lifetime Support Policy prints months and says each stage of support is provided through the last day of the month. Cloudera's support lifecycle policy prints months, which its own page reads as the end of the month. SAP's maintenance schedules print months, and SAP's own knowledge base article for BI 4.3 renders its December 2026 as an exact last day. kernel.org projects the end of a longterm branch as a month. For all of these, the day we serve is the last day of the stated month, and we say so on each product page.

Two vendors land a day apart. Microsoft's lifecycle page gives Office Online Server a retirement instant of 1/1/2027 6:59:59 AM Pacific, which is the same moment as the end of December 31, 2026 in that time zone, so it joins the December list. Check Point prints its appliance milestones as months with no day convention; our Check Point page records a month as its first day, the conservative reading, which is why the 44000 and 64000 chassis appear under January 1, 2027 and not December 31. Oracle Solaris 10 and 11.3 are served with an Extended Support end of January 1, 2027, the date our Solaris guide verified against Oracle's Lifetime Support Policy brochure for Oracle and Sun system software.

Every row on the day

Grouped by what a team should do about it. The Date column is the value we serve; the last column is the guide that carries the detail where one exists, otherwise the product page.

One row the horizon lists is deliberately absent: HAProxy 3.3. HAProxy prints its end-of-life as a quarter, and since October 2026 our data serves the branch as not yet announced rather than as a day, so it has no date to put in this table. Its live status is on the HAProxy page.

The web runtime: PHP 8.2 ends, PHP 8.4 changes phase

Two PHP rows share the day and mean different things. PHP 8.2, released December 8, 2022, left active support on December 31, 2024 and reaches end of life on December 31, 2026: PHP's supported-versions table lists no phase for the branch after that date. PHP 8.4 leaves active support on the same December 31, 2026, but its end-of-life date is December 31, 2028, so an 8.4 application is not facing a cliff; it is entering the second half of its window.

Where to go. Our PHP 8.2 end-of-life guide puts it plainly for an application whose framework allows it: upgrade PHP in place to 8.3, 8.4 or 8.5, with no framework jump needed. The three targets' own dates, as served: 8.3 ends on December 31, 2027, 8.4 on December 31, 2028, and 8.5, in active support to December 31, 2027, on December 31, 2029. The guide's framework table is the part to read if the application is on Laravel, Symfony or a CMS, because the framework's own PHP ceiling decides which of the three is reachable. A year-end date also means the real change window closes before December's freeze; the guide says the same.

The Java stack: Spring Boot, Spring Security, Spring Cloud and Micrometer version together

Spring's projects move as a set. A Spring Boot generation binds a Spring Security and a Spring Cloud release train and a Micrometer line, and their open-source and commercial windows end on the same days. On December 31, 2026 that produces six rows from one policy table:

Where to go. For the open-source rows the destination is the next generation: Spring Boot 4.1, released June 10, 2026, with open-source support to July 31, 2027 and commercial support to July 31, 2028; Spring Security 7.1 and Spring Cloud 2025.1, both to July 31, 2027; and Micrometer 1.17, the line Spring's table ties to Boot 4.1, to July 31, 2027. Within a major these are version bumps; our Spring Boot guide covers every line from 1.5 to 4.1 with what changes between versions and how to plan the upgrade. The commercial rows are different: a team paying for Spring Boot 3.4 support loses it on the day, and the 3.x generation Spring marks for long commercial support is 3.5, whose open-source window closed on June 30, 2026 but whose commercial window runs to June 30, 2032; Spring Security 6.5 and Spring Cloud 2025.0 carry the same June 30, 2032. Our Spring June 30 wave guide explains why the whole stack moves on one day and what the commercial window does and does not include.

Oracle: five Fusion Middleware 12.2 products, APEX 24.1, and Solaris one day later

Oracle's Fusion Middleware Lifetime Support Policy gives Fusion Middleware 12c (12.2.x) Premier Support ending December 2026 and Extended Support ending December 2027, and says the 12c releases of its other middleware products follow that row. We serve those as December 31, 2026 and December 31, 2027 for WebLogic Server 12.2, ADF 12.2, Forms and Reports 12.2, HTTP Server 12.2 and SOA Suite 12.2. After Extended Support, Oracle's Sustaining Support continues indefinitely but, per our product notes, delivers no new security fixes. Three of these products already appear in CISA's Known Exploited Vulnerabilities catalog: ADF through CVE-2022-21445, whose Oracle advisory names the 12.2.1.3.0 and 12.2.1.4.0 releases, and WebLogic Server and HTTP Server through CVE-2026-21962, covered in our WebLogic CVE-2026-21962 guide.

Where to go. Our Fusion Middleware 12c guide names Fusion Middleware 14c (14.1.x), which Oracle lists with Premier Support to December 31, 2030 and Extended Support to December 31, 2033, covering the same product set. For WebLogic Server alone Oracle also lists WebLogic 15, Premier Support to October 31, 2030. The guide carries the per-product tables and the policy quotes.

Oracle APEX 24.1, released June 17, 2024, reaches end of life on December 31, 2026. Nothing on file names a target; the Oracle APEX page lists every release with its date.

One day later, on January 1, 2027, Oracle Solaris 10 and 11.3 leave Extended Support under Oracle's Lifetime Support Policy for Oracle and Sun system software. Our Oracle Solaris guide calls this the real Solaris deadline, because the estates still running "supported Solaris" are disproportionately on those two releases, and names Solaris 11.4, Premier Support to November 1, 2031 and Extended Support to November 1, 2037, as the release with the runway.

Microsoft: Office Online Server is retired

Office Online Server, released May 4, 2016 as the successor to Office Web Apps Server, is retired on December 31, 2026. It is serviced under Microsoft's Modern Lifecycle Policy as a single product line, which is why it appears on none of Microsoft's year-by-year end-of-support lists; the only public date is on its own lifecycle page, which states the retirement as 1/1/2027 6:59:59 AM Pacific. After that it receives no security updates, bug fixes or technical support. It is a dependency rather than a headline product: the server that renders browser-based Word, Excel, PowerPoint and OneNote for SharePoint Server, Exchange Server and Skype for Business farms, installed once and forgotten.

Where to go. Our Office Online Server retirement guide gives Microsoft's stated paths: Microsoft 365 (Office for the web) for browser editing, desktop Office for on-premises servers, and SharePoint Embedded for in-app co-authoring. Excel workbooks hosted in Power BI Report Server through Office Online Server lose that function entirely.

Infrastructure platforms: Nutanix, SLES, OpenShift, Cloudera and the kernel

Nutanix AOS 7.0 and Prism Central pc.2024.3

Nutanix AOS 7.0, released December 4, 2024, left maintenance on March 31, 2026 and reaches End of Support Life on December 31, 2026. Prism Central pc.2024.3, released December 5, 2024, runs the same two clocks: maintenance ended March 31, 2026, End of Support Life December 31, 2026. Where to go. Our Nutanix AOS 6.10 guide rules 7.0 out as a landing point for exactly this reason and names AOS 7.5, maintained to March 31, 2027 with End of Support Life December 31, 2027, as the conservative target and 7.6, End of Support Life July 31, 2028, as the longer one. For the matching Prism Central release, see the Nutanix Prism page.

SUSE Linux Enterprise Server 15 SP4

SLES 15 SP4, released June 21, 2022, left general support on December 31, 2023; its Long Term Service Pack Support ends on December 31, 2026. A system still on SP4 has been running on the long-term extension since general support ended and loses it on the day. Nothing on file names the service pack to move to; the SLES page lists every service pack with its general and long-term dates. The SP4 kernel is a distribution kernel, so the kernel.org dates below do not apply to it; our kernel guide explains the distinction.

Red Hat OpenShift 4.22

This one is a calendar note, not a cliff. OpenShift 4.22, released June 9, 2026, leaves full support on December 31, 2026; maintenance support runs to December 31, 2027, and as an even-numbered release its Extended Update Support term runs to June 30, 2028. Our OpenShift 4.18 guide explains the even/odd EUS rhythm and which subscriptions include the EUS term.

Cloudera Platform 7.3.1

Cloudera 7.3.1, released in December 2024, reaches End of Support on December 31, 2026, after which Cloudera's policy says it no longer supports the release, including bug fixes and security patches. Where to go. Our Cloudera 7.3.1 guide names 7.3.2, the release that carries Cloudera's Long Term Support mark, supported to March 31, 2032, and notes that Cloudera certifies in-place upgrades from 7.3.1 and its service packs.

Linux 5.10 and 5.15

kernel.org projects the end of both the 5.10 and 5.15 longterm branches in December 2026; it prints the month, calls the date projected, and we serve the last day, December 31, 2026. Where to go. Our Linux 5.10 and 5.15 guide names 6.12 and 6.18, both projected to December 31, 2028, and is explicit that distribution kernels (RHEL, Ubuntu, Debian, SLES) run on the distribution's dates, not kernel.org's. The branch matters most for appliances and embedded systems that build from upstream.

Service mesh: Istio 1.30 and the Kiali versions tied to it

Istio 1.30, released May 14, 2026, is served with an end of life of December 31, 2026; Istio prints the month and marks it expected, because its rule is six weeks after the release two minors later. Kiali publishes no dates of its own: its rule is that supported Kiali versions are the ones associated with supported Istio versions, and its compatibility table lists Istio 1.30 with Kiali 2.26 and higher, so Kiali 2.26 through 2.31 leave support with Istio 1.30 on December 31, 2026. Where to go. Our Istio 1.29 guide names 1.31, released August 27, 2026 and expected to end on February 28, 2027. For Kiali, our Kiali guide notes that Kiali's table had no Istio 1.31 row when it was read; when Kiali adds one, the versions in it stay supported for as long as Istio 1.31 is.

Appliances and devices: PaperCut, QNAP, Meraki, Check Point, Intel

PaperCut NG/MF 23

PaperCut NG/MF 23, released October 30, 2023, has two end dates on PaperCut's policy page: September 30, 2026 for customers without current Maintenance and Support, and December 31, 2026 for customers with it. PaperCut's own security advisory draws a narrower line: it says there are no emergency patches or maintenance releases for version 23 or earlier. Where to go. Our PaperCut advisory guide quotes PaperCut's instruction to upgrade to a currently supported version line: 24, 25 or 26.

QNAP ES1686dc, ES2486dc, TDS-16489U R2 and TS-2888X

Four QNAP NAS models reach the end of Technical Support and Security Updates on December 31, 2026 per QNAP's Product Support Status page: the ES1686dc and ES2486dc dual-controller enterprise units, the TDS-16489U R2 dual-processor server and the TS-2888X. Where to go. Our QNAP NAS guide records that QNAP names one successor, the ES1686dc R2 for the ES1686dc; the other three have none listed. The guide also explains why a QNAP appliance past its security-update date should not stay reachable from the internet.

Cisco Meraki MR36, MR36H, MR44, MR46 and MR46E

This row is an end of sale, not an end of support. Meraki's End-of-Life Products and Dates page lists the MR36, MR36H, MR44, MR46 and MR46E access points with an End-of-Sale date of December 31, 2026 and an End-of-Support date of December 31, 2031. After the first date the units can no longer be ordered; Meraki's policy says it typically supports a product for five years after the end-of-sale date. Nothing on file names a replacement; the Cisco Meraki page and our Cisco Meraki guide carry every model's dates.

Check Point 44000 and 64000 chassis, SSM440 and SGM400

On Check Point's Support Life Cycle Policy page the 44000 Chassis, 64000 Chassis, SSM440 and SGM400 reach End of Engineering Support in January 2027, served as January 1, 2027 under the first-day rule our Check Point page applies to month-only cells, and End of Support in January 2029, served as January 1, 2029. In Check Point's words, engineering support means maintenance releases are supplied; after it, software upgrades and bug fixes continue to the End of Support date. Check Point's page lists Maestro as the successor for the two chassis. The Check Point appliances page has every model.

Intel Ice Lake

Intel's Ice Lake generation, launched in 2019, carries an end date of December 31, 2026 in our data. This is a hardware row with no upgrade target on file; the Intel processors page lists every generation.

SAP BusinessObjects BI 4.3

SAP's knowledge base article 3763590 gives BI 4.3 an exact day for the end of mainstream maintenance, which we serve as December 31, 2026; SAP's strategy document describes it as a one-year extension. SAP's strategy document says 4.3 will be supported beyond 2026 in Customer Specific Maintenance, with security fixes for high-severity issues during the first twelve months of that phase, but prints no date for the end of it, so our page shows no end-of-life date for 4.3. Where to go. The next line SAP lists is BI 2025, mainstream maintenance to December 31, 2027 and its last security-fix phase ending December 31, 2028. The SAP BusinessObjects page carries SAP's phase definitions.

The order of work

1. Separate the cliffs from the phase changes. PHP 8.2, Spring Boot 4.0 open-source, Cloudera 7.3.1, Nutanix AOS 7.0 and Prism pc.2024.3, SLES 15 SP4 LTSS, the four QNAP models, PaperCut 23 and the Oracle 12.2 products without Extended Support are cliffs. PHP 8.4, OpenShift 4.22, SAP BI 4.3 and the Meraki MR36 line are phase changes with a later date still ahead.
2. Buy or decline the paid windows deliberately. Spring Boot 3.4, Spring Security 6.4, Spring Cloud 2024.0 and Micrometer 1.14 commercial support ends on the day; Oracle 12.2 Extended Support runs to December 31, 2027 at a price. A line item in a support contract decides whether a December date is a deadline or a reminder.
3. Move the year-end work into November. Every date here is December 31, inside most organizations' change freeze. The PHP and Spring upgrades are version bumps that fit a sprint; the Oracle, Nutanix and Cloudera moves are projects that do not.
4. Check the inventory for the quiet ones. Office Online Server, the Check Point SSM and SGM modules, a 5.10 kernel inside an appliance and an Ice Lake server fleet are the rows least likely to be on anyone's list.
5. Watch the pages, not this hub. Each product page re-reads its vendor source at every build; a date that moves shows up there first. The 2026 EOL calendar lists every tracked product's dates for the year, and EOL Watch carries what comes after.
