¶1OPINION
¶2delivered the opinion of the Court
¶3We file and set this habeas corpus case to decide whether applicant’s previous first-degree-felony burglary conviction makes him ineligible for release on mandatory supervision for his 2002 second-degree-felony burglary conviction. We find that it does not, and, therefore, we grant relief.
¶5Applicant is currently serving a four-year sentence for a second-degree-felony burglary committed on October 10, 2002. Applicant alleges that the Texas Department of Criminal Justice, Correctional Institutions Division (TDCJ-CID) is wrongly denying him consideration for release on mandatory supervision under Section 508.149 of the Government Code on this present or holding offense due to his prior conviction for first-degree-felony burglary. TDCJ-CID states that applicant is “not eligible for mandatory supervision due to prior conviction of 1st Degree Burglary of a Habitation under Cause # 18,704 as set out in [Tex. Gov’t Code § 508.149(a) ].” The trial court agreed with TDCJ-CID’s position.
¶6II.
¶7The statute in effect when the holding offense is committed determines an inmate’s eligibility for release on mandatory supervision or parole.
¶8The question presented here, left unanswered by this Court in Ex parte Mabry,
¶9Furthermore, at the time applicant committed his holding offense in 2002, only those burglaries of a habitation which in*460volved the intent to commit (or actual commission of) some felony other than theft were classified as first degree felonies.
¶10As stated above, the mandatory supervision statute that applies to applicant’s holding offense provides: “An inmate may not be released to mandatory supervision if the inmate is serving a sentence for or has been previously convicted of ... a first degree felony under Section 30.02, Penal Code.” But the offense of burglary of a habitation with intent to commit theft is not included in the 2002 Section 508.149(a) list of offenses which render an inmate ineligible for release on mandatory supervision.
¶11Thus, the following question arises: Does “a first degree felony under Section 30.02, Penal Code” on the list of prior convictions ineligible for release on mandatory supervision mean “first degree felony” at the time the prior conviction was committed in 1987 (applicant would be ineligible for release) or at the time he committed the present offense in 2002 (applicant would be eligible for release)? In Ex parte Mabry,
¶12Literally applying the words of Section 508.149(a) — “[a]n inmate may not be released to mandatory supervision if the inmate is serving a sentence for or has been previously convicted of ... a first degree felony under Section 30.02” — applicant would be ineligible for release on mandatory supervision based on criminal conduct which itself has never been classified as “mandatory supervision ineligible.”
¶13As we explained in Ex parte Ervin,
¶14In Ervin, we held that the legislature could not have reasonably intended to make inmates convicted under the predecessor statute to the present sexual assault law eligible for mandatory supervision release, while making ineligible those convicted of the same conduct under the current statutory title.
¶15As in Ervin, we look to whether the essential characteristics (the criminal conduct, mental state, and accompanying circumstances) of the previous conviction, not the mere title, are on the current list.
¶16Applicant is entitled to relief.

¶41concurring.
¶42The question we confront today is whether a prior 1987 conviction for the offense of “burglary of a habitation with the intent to commit theft,” a first degree felony at that time, renders applicant ineligible for mandatory supervision on the new offense for which he is currently incarcerated. I agree with the Court that it does not, but I would analyze the issue a little differently.
¶43A person’s eligibility for mandatory supervision is determined by the statute in effect at the time the inmate’s holding offense was committed.
¶44We have already decided that for a prior conviction to render an inmate ineligible for mandatory supervision, the prior conviction must be on the current list of ineligible offense.
¶45The answer to that question is found in Government Code § 311.027, which states: “Unless expressly provided otherwise, a reference to any portion of a statute or rule applies to all reenactments, revisions, or amendments of the statute or rule.”
¶46*463So, the legislature has specifically prescribed how to treat one statute’s reference to another statute. The referencing statute is essentially “updated” by any changes to the referenced statute. Deciding which version of a reference statute applies is a simple matter of determining which version of the referencing statute applies.
¶47Here, the 2002 version of the referencing statute (§ 508.149(a)) applies because applicant committed his holding offense in 2002. So the 2002 version of the referenced statute (Penal Code § 80.02) is the applicable statute. In 2002, burglary of a habitation with intent to commit theft was not a first degree felony; rather, it was a second degree felony. Consequently applicant’s offense is not on the list of ineligible offenses, and he is entitled to relief.
